BOLOCAM is a large format, mm-wave camera used at the Caltech Sub-millimeter Observatory to achieve high mapping speed and 1' resolution.
BOOMERANG
The final flight of Boomerang is complete! In January of 2003, Boomerang flew an exact prototype of the polarized 143 GHz Planck HFI focal plane, resulting in the first bolometric detection of CMB polarization. The first round of analyses of the B03 data are complete, papers and spectra have been made public 7/21/05.
BICEP2 builds on the small aperture telescope design of BICEP1, but greatly increases the number of detectors to increase mapping speed. The BICEP2 detectors are polarization sensitive bolometers made from a pair of transition edge sensors coupled to orthogonal phased antenna arrays. The transition edge sensors provide background-limited sensitivity at the observing frequency of 150 GHz while antenna arrays improve the scalability of the design. BICEP2 operated from the Dark Sector Lab at Amundsen-Scott South Pole Station from January 2010 through December 2012. Read more about this project here.
