Abstract


Characteristics of 14 m MM wave telescope of TRAO with a multibeam focal plane array (FPA) are considered. Simulation shows that 7x7 element tightly packed FPA at 85-115 GHz is a highly effective instrument for 14 m telescope. Expected beam spacing is 1.5-2*HPBW, the field of view is up to 12’x12’. Estimated FPA sensitivity with the suggested receiver scheme is 5-10 mK/s1/2 per beam per channel. 14 m TRAO telescope with 7x7 FPA and 1-20 GHz filterbank backends may be used for mapping in continuum and some spectral astrophysical tasks.
