Numerous ALMA staff worldwide remain actively involved in the preparation of the ALMA Wideband Sensitivity Upgrade (WSU). Regarding the advancement of development projects within the ALMA regions, the Data Transmission System successfully completed its Preliminary Design Review in Japan in October. Additionally, the Conceptual Design Review and the System Requirement Review for the Total Power GPU Spectrometer were also passed in October.
Update on the Wideband Sensitivity Upgrade
Published: 28 Nov 2024
A significant European contribution to the WSU, the Wideband IF Processor, conditionally passed its Preliminary Design Review in Bordeaux a few days ago. This project is essential within the WSU signal chain, as it aims to digitize the analog receiver signals across a broad IF bandwidth, thereby providing up to four times the current IF bandwidth to the new correlator.
Alongside these WSU development initiatives, considerable effort has been dedicated to designing the Assembly, Integration, Verification, and Commissioning process. This plan outlines in detail how the various components of the WSU will be integrated in Chile to collectively deliver the capabilities of the WSU.
