Installing a Receiver on the GBT, March 2004
On a floating platform suspended from the 64-foot high feed arm on the Green Bank Telescope is the room that houses its eight receivers. In this photo, a large feed horn for a long wavelength receiver is being steadied so that a cryogenic pump can be attached. The supercooled receiver will collect the waves funneling down this horn and send them along fiber to the computers nearly two miles away in the noise-shielded control room.
