In this paper, the optical performance of the ALMA Band 8 (385–500 GHz) cartridge receiver (S/N 01), which is the first one of 80 shipments, was investigated. ALMA Band 8 cartridge receiver consists of a corrugated horn, an Ortho-Mode Transducer, an elliptical mirror, a local oscillator, IF amplifiers, and superconducting-insulator-superconducting (SIS) mixers which cover IF frequency range from 4 to 8 GHz. The amplitude and phase of electric field at near-field were probed, and then the far… CONTINUE READING
