ALMA is implementing the Wideband Sensitivity Upgrade (WSU) to address the ALMA 2030 Development Roadmap and keep ALMA at the forefront of astronomical discovery. The WSU will bring major observing improvements, including increased instantaneous bandwidth (by at least 2x), improved sensitivity, and higher spectral resolution across wider bandwidths than is currently possible with ALMA. To help ALMA assess user support needs over the next decade we invite your input via the following ALMA user survey.
ALMA User Survey
Published: 29 Sep 2026
ESO encourages input from all current, past, and prospective ALMA users. The survey will remain open until 31 October, 2026.
Thank you in advance for your contributions to this important process!
