Spider (polarimeter)
text:
Spider is a balloon-borne experiment designed to search for primordial gravitational waves imprinted on the cosmic microwave background (CMB). Measuring the strength of this signal puts limits on inflationary theory. The Spider instrument consists of six degree-resolution telescopes cooled to liquid Helium temperature (4 K) which observe at frequencies of 100 GHz, 150 GHz, and 280 GHz. Each telescope is coupled to a polarisation-sensitive transition-edge bolometer (TES) array cooled to 300 mK. S
