Radiotelescopes
I'm currently working at the
Cosmic Background Imager
(CBI) of the California Institute of Technology
Cryogenic Systems
At the CBI we're running Grifford-McMahon fridges to cool down our receivers to 6ºK, closed cycle He gas.
Low Noise Amplifiers
The LNAs of the CBI receivers are HEMTs operating in the 26-36 GHz frequency window.
Site testing for telescopes
I'm involved in the site testing for the
Cornell-Caltech Atacama Telescope
(CCAT) and the
CLOVER
(U. of Cardiff, UK).
Antennas
I did simulations of a 2D antenna with FDTD in Matlab.
