| Abstract: This paper describes the mechanical design of the KMOS pick-off arms and the way in which the design is driven by combinations of requirements. The use of a recirculating linear bearing in a cryogenic environment is novel and the qualification of this component is described. Novel use is made of a single leadscrew with two leads to move optical components at different speeds to maintain the optical path length. Cryogenic flexure, repeatability and torque tests are described. | |||||

| Abstract: KMOS is a second generation near infrared multi-object spectrograph instrument for the VLT. It is a highly complex astronomical instrument with over 60 cryo-mechanisms deploying pickoff arms, moving filter wheels and detector focus stages. The instrument houses three identical sections each consisting of 8 pickoff arms, 2 filter wheels, 8 integral field units feeding a spectrograph and its detector systems. The housekeeping electronics provides a semi-automation of the cryostat functions such as pump down, cool down and warm up sequences, vacuum and temperature measurement and control etc. The infrastructure electronics is responsible for the safe operation of the instrument. It monitors the various cryostat conditions, takes automatic corrective actions under faulty conditions and raises alarms when a manual intervention is needed. This semi-automation design is aimed at not only minimising the risk of instrument damage, but also takes into account the safety of instrument manual handling. This paper describes the design of the instrument infrastructure electronics and details its functions such as semi-automation of the cryostat procedures, housekeeping diagnostics, automatic corrective actions under faulty conditions, scheme of alarm and warnings, detector thermal protection etc. and presents the associated interfaces to the control electronics and the cable co-rotator. | |||||

| Abstract: KMOS is a 2nd generation instrument under development for the VLT. It is a near-infrared multiple integral field spectrograph which captures 24 fields of 2.8Prime times 2.8Prime anywhere within a 7.2prime field to feed 24 IFUs at a resolution of 0.2Prime. It is made up of three stages: the pickoff system which captures the 24 images, the slicer system and the spectrographs. The slicer system is then the optical link between the 24 images captured by the pickoff system and the three slits in front of the three spectrographs. It is made of 24 Advanced Image Slicer systems similar to the IFU which the Centre for Advanced Instrumentation built for the Gemini Near-Infrared Spectrograph (GNIRS) except for two modifications. The fore-optics of each system is made of three toroidal mirrors that accomplish a series of tasks: transfer of the field image, positioning of the pupil, and magnification of the image, resulting in anamorphic magnification, high image quality, and the possibility of rotating the image. | |||||

| Abstract: KMOS is a 2nd generation instrument in project for the VLT. It is an NIR multi-object integral-field spectrograph capturing 24 fields of 2.8'' times2.8'' anywhere on a 7.2' field. The 24 fields are fed to 24 IFUs with a resolution of 0.2''. KMOS is made of 3 stages: the pickoff system which captures the 24 images, the slicer system and the spectrographs. The slicer system is then the optical link between the 24 images captured by the pickoff system and the 3 slits in front of the 3 spectrographs. It is made of 24 Advanced Image Slicer systems similar to the GNIRS IFU except for 2 modifications: there are 3 mirrors with power in the fore-optics instead of 2 and there are 2 lines of pupil mirrors instead of one. The fore-optics of each system is made of 3 off-axis aspheric mirrors that accomplish a series of task: transfer the field image, position the pupil, magnify the image, give an anamorphic magnification to the image, and give a high image quality. The possibility of rotating the image with the fore-optics has also been studied. | |||||

inproceedings | DOI |
| Abstract: KMOS is a multi-object near-infrared integral field spectrometer with 24 deployable pick-off arms. Data processing is inevitably complex. We discuss specific issues and requirements that must be addressed in the data reduction pipeline, the calibration, the raw and processed data formats, and the simulated data. We discuss the pipeline architecture. We focus on its modular style and show how these modules can be used to build a classical pipeline, as well as a more advanced pipeline that can account for both spectral and spatial flexure as well as variations in the OH background. A novel aspect of the pipeline is that the raw data can be reconstructed into a cube in a single step. We discuss the advantages of this and outline the way in which we have implemented it. We finish by describing how the QFitsView tool can now be used to visualise KMOS data. | |||||

inproceedings | DOI |
| Abstract: Durham University's Centre for Advanced Instrumentation (CfAI) are currently prototyping key components for the KMOS and JWST NIRSpec Integral Field Units (IFUs). These next-generation IFUs will make extensive use of complex monolithic multi-faceted metal mirror arrays, which are fabricated by means of freeform diamond machining. Using this technique, the inherent accuracy of the diamond machining equipment is exploited to achieve the required relative alignment accuracy of the facets, as well as obtain the necessary optical surface quality for each individual facet, thus facilitating the integration and subsequent testing of these complex systems. The CfAI have pioneered the use of such arrays in the IFU for the Gemini Near-InfraRed Spectrograph (GNIRS IFU), which was installed at Gemini South in April, 2004. The requirements for the next generation of IFUs, however, demand a considerable improvement in the optical performance of these components, e.g. alignment accuracy of the facets, surface form accuracy and roughness. In our paper we briefly discuss the optical designs of KMOS and JWST NIRSpec IFU, and summarise the requirements on the optical components. We then present details of the diamond machining techniques employed to fabricate these highquality components and discuss the latest results from our prototyping activities, which demonstrate our capability of producing optical components that meet the demanding specifications. | |||||

inproceedings | DOI |
| Abstract: The KMOS Instrument is built to be one of the second generation VLT instruments. It is a highly complex multi-object spectrograph for the near infrared. Nearly 60 cryogenic mechanisms have to be controlled. This includes 24 deployable Pick-Off arms, three filter and grating wheels as well as three focus stages and four lamps with an attenuator wheel. These mechanisms and a calibration unit are supervised by three control cabinets based on the VLT standards. To follow the rotation of the Nasmyth adaptor the cabinets are mounted into a Co-rotating structure. The presentation will highlight the requirements on the electronics control and how these are met by new technologies applying a compact and reliable signal distribution. To enable high density wiring within the given space envelope flex-rigid printed circuit board designs have been installed. In addition an electronic system that detects collisions between the moving Pick-Off arms will be presented for safe operations. The control system is designed to achieve two micron resolution as required by optomechanical and flexure constraints. Dedicated LVDT sensors are capable to identify the absolute positions of the Pick- Off arms. These contribute to a safe recovery procedure after power failure or accidental collision. | |||||

| Abstract: KMOS is a second generation instrument in construction for use at the European Southern Observatory (ESO) Very Large Telescope (VLT). It operates in the near-infrared (0.8 to 2.5 microns) and employs 24 deployable, image slicing integral field units (IFUs) feeding three spectrographs. The spectrographs are designed and built by a partnership of the University of Oxford and Rutherford Appleton Laboratories (RAL). We describe the assembly, integration and alignment procedures involved in the construction of these spectrographs in detail. We also present the results of the cryogenic optical tests, including the first data taken through the full spectrograph optical train and the details of the test facility and procedures involved. | |||||

| Abstract: When it is delivered to the VLT KMOS, will be the first near infrared (0.8-2.5 $m) spectrograph to use multiple integral fields units. Pick-off arms provide the optical relay to image objects selected from the patrol field at the Nasmyth focus onto 24 image slicing IFUs. The output from 8 IFUs forms a single slit which feeds one of three identical spectrometers. The calibration of such an instrument presents a number of challenges. Flat field and wavelength calibration for the instrument will be provided by an internal calibration system of unique design. External light sources are fed via integrating spheres and high transmission light pipes to a calibration sphere with 24 output ports addressed by the 24 arms. Obtaining a high degree of field flatness is key to the sensitivity of NIR instruments. The KMOS calunit is predicted to deliver flatnesses of tilde0.1% over the KMOS IFU fields. | |||||

| Abstract: The pick-off arm is the part of the KMOS instrument which re-images a sub-field of the VLT focal plane to a position outside of the main field where it can be used for integral field spectroscopy. In this paper we describe the optical alignment and test procedure developed to meet the challenging alignment requirements of the instrument. It is important to note that although the alignment is done at ambient temperature, the alignment of the optical components must be maintained at the instruments cryogenic operational temperature. This paper describes the methods used to achieve the absolute positioning accuracy and the test results obtained and discussed some of the practical difficulties that were encountered. | |||||

| Abstract: The heart of the KMOS instrument is a complex optical system with over 300 separate optical paths. The optical design is spread between 4 sub-systems which have been designed at three different institutions. In order that the end to end performance of the final design can be monitored and controlled it is necessary to specify the performance and interface requirements of each sub-system clearly. This paper describes the parameters that were necessary to control so that the sub-system designs could be carried out independently while maintaining visibility and control of the end to end performance. The method of apportioning the budgets between the sub-systems and the modeling performed to verify compliance is also described. | |||||

| Abstract: We describe a proposed 2nd generation instrument (KMOS) for the ESO VLT which will deliver a unique multiple integral field capability in the near-infrared (1-2.5 $m). The science drivers for such an instrument are presented and linked to the functional specification. The overall instrument concept is discussed in the context of two proposed solutions for delivering a deployable integral field capability. Detailed discussions of these two approaches, and ongoing prototype studies, are described in separate papers. | |||||

inproceedings | DOI |
| Abstract: We present the optical and mechanical design of the KMOS spectrograph module together with a detailed analysis of its performance. KMOS is a cryogenic near-infrared multi-object spectrograph being developed as a second-generation instrument for the VLT by a consortium of UK and German institutes. Three identical spectrograph modules provide Nyquist sampled spectra in the wavelength range covering the atmospheric bands z, J, H, and K with a resolving power exceeding 3200. The spectrographs are fully achromatic over the bands and the single mirror collimator and six-element camera, together with six high efficiency gratings provide high throughput. The optical performance analysis includes amongst others the spectral resolving power and variation of the PSF as a function of the pupil illumination. | |||||

| Abstract: We present the results of a design study for the spectrograph module for KMOS - a cryogenic near-infrared multi-object spectrograph being developed as a second generation instrument for the VLT by a consortium of UK and German institutes. KMOS will consist of 24 deployable integral field units feeding three identical spectrograph units via image slicers. The spectrographs are designed to provide a resolving power greater than 3000, so as to provide adequate OH avoidance, whilst covering one of the J, H or K bands within a single exposure. We present the opto-mechanical layout of the spectrographs, together with an analysis of the impact of the image quality (and PSF uniformity) on the accuracy of sky background subtraction within each IFU's field of view. | |||||

inproceedings | DOI |
| Abstract: KMOS is a cryogenic multi-object near-infrared spectrograph for the VLT. It will be equipped with about 20 deployable integral field units (IFUs) which can be positioned anywhere in the 7.2 arcmin diameter field o the VLT Nasmyth focus by a cryogenic robot. We describe IFUs using micro lens arrays and optical fibers to arrange the two-dimensional fields from the IFUs on the spectrograph entrance slit. Each micro-lens array is mounted in a spider arm which also houses the pre-optics with a cold stop. The spider arms are positioned by a cryogenic robot which is built around the image plane. For the IFUs, two solutions are considered: monolithic mirco-lens arrays with fibers attached to the back where the entrance pupil is imaged, and tapered fibers with integrated lenses which are bundled together to form a lens array. The flexibility of optical fibers relaxes boundary conditions for integration of the instrument components. On the other hand, FRD and geometric characteristics of optical fibers leads to higher A$ accepted by the spectrograph. Conceptual design of the instrument is presented as well as advantages and disadvantages of the fiber IFUs. | |||||

inproceedings | DOI |
| Abstract: KMOS is a near-infrared multi-object spectrometer, which is currently being built by a British-German consortium for the ESO VLT. As for any other VLT instrument, the KMOS instrument software is based on the application framework given by the VLT Common Software, but faces particular design challenges in addition. As separate parts of the software require a similar functionality with respect to mechanical and optical permissibility checks, user interface, and configuration control, a number of tasks have to be implemented twice and slightly differently. It turns out that most of these issues can be tackled successfully by means of well-known object-oriented design patterns, providing for reusability and improving the overall software design. We present a set of sample problems along with their particular pattern solution. | |||||

inproceedings | DOI |
| Abstract: KMOS is a multi-object integral field spectrometer working in the near infrared which is currently being built for the ESO VLT by a consortium of UK and German institutes. It is capable of selecting up to 24 target fields for integral field spectroscopy simultaneously by means of 24 robotic pick-off arms. For the preparation of observations with KMOS a dedicated preparation tool KARMA (''KMOS Arm Allocator'') will be provided which optimizes the assignment of targets to these arms automatically, thereby taking target priorities and several mechanical and optical constraints into account. For this purpose two efficient algorithms, both being able to cope with the underlying optimization problem in a different way, were developed. We present the concept and architecture of KARMA in general and the optimization algorithms in detail. | |||||
