It is anticipated that 4000 hours of the 12-m Array time and 3000 hours of the Atacama Compact Array (ACA) time, also known as the Morita Array, will be available for successful proposals from Principal Investigators (PIs) in Cycle 6.  Proposals must be prepared and submitted using the ALMA Observing Tool (OT), which is available for download from the ALMA Science Portal. Proposals will be assessed by competitive peer review by a single international review committee.

The ALMA Cycle 6 proposal submission deadline is 15:00 UT on Thursday, 19 April 2018.

ALMA provides continuum and spectral-line capabilities for wavelengths from 0.32 mm to 3.6 mm, and angular resolutions from 0.018” to 3.4” on the 12-m Array. Cycle 6 will bring to ALMA several new observational capabilities, including full circular polarization observations, lifting of some restrictions for simultaneous observations with the 12-m Array and the ACA, Band 8 stand-alone ACA observations and an increase of the Band 6 Intermediate Frequency (IF) bandwidth. 

The ALMA Proposer’s Guide provides an overview of significant changes made in both the technical capabilities and observing strategies for Cycle 6, an overview of the ALMA organisation, the types of proposals offered in Cycle 6, information on proposal planning and submission, an overview of the offered technical capabilities, and guidelines for writing a Technical Justification .
