CMB Research at UW-Madison

We develop and deploy instruments capable of high levels of sensitivity necessary to detect the extremely weak CMB signals.

Current Projects:

• Millimeter-Wave Bolometric Interferometer (MBI)

• Data Analysis
• Mount and Location Construction
• Phase Modulators

• Bolometers

• Superconducting Transition Edge Sensors (TES)
• Monolithic Silicon Bolometers
• Bismuth Microbolometers Neutron Detectors
