Description
The ALMA Wideband Sensitivity Upgrade (WSU) is an ongoing partnership-wide initiative that will dramatically increase the ALMA system’s observing efficiency across ALMA’s entire wavelength range and for all observing modes. As part of the WSU, most of the observatory’s hardware elements will be replaced or upgraded, including key receivers and signal chain components; a new correlator, the Advanced Technology ALMA Correlator -ATAC) will be installed.
This comprehensive system rehaul will result in a transformational increase of the instantaneously correlated bandwidth, up to at least 16 GHz per polarization for all receivers, combined with significantly improved receiver and digital path efficiency. The entire instantaneously correlated bandwidth will be accessible at any spectral resolution, so that observers will not need to trade bandwidth for spectral resolution, significantly increasing the efficiency of spectral scans for redshift and chemical surveys. The large gain in continuum mapping speed (increased by a minimum factor of 3) directly translates in improved ability to efficiently detect and map fainter and farther sources, from asteroids to forming planets and dusty galaxies at high redshifts.
In this talk I will present the scope of the WSU, the status of the project and its impact on a variety of scientific cases.
