ALMA2030 WSU
The Atacama Large Millimeter/submillimeter Array (ALMA) is the largest (sub)mm-wavelength ground-based telescope and has been producing ground-breaking science since it became operational in 2011. However, it was built using technology from the early 2000s to serve the top-level scientific goals defined by the Scientific Community at that time. 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 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).
