ALMA Wideband Sensitivity Upgrade

ALMA became operational in 2011. The ALMA Development Roadmap was released in 2018 to prioritize the development necessary to significantly expand ALMA’s capabilities and enhance its scientific reach in the coming decades. The top priority based on scientific merit and technical feasibility was defined as the broadening of the receiver Intermediate Frequency (IF) bandwidth by at least a factor of two and the upgrade of the associated electronics and correlator. This initiative to implement this priority is now known as the ALMA2030 Wideband Sensitivity Upgrade (WSU).
