INTEGRATED SUPERCONDUCTING SPECTROMETER FOR ATMOSPHERE MONITORING V. P. Koshelets, P. N. Dmitriev, A. B. Ermakov, L. V. Filippenko, O. V. Koryukin, M. Yu. Torgashin, A. V. Khudchenko In this pap er the results of the development of submm Sup erconducting Integrated Receiver (SIR) for monitoring of the Earth atmosphere from the b oard of the high-altitude ballo ons are presented. The micro circuit of the sup erconducting integrated receiver comprising lo cal oscillator based on long Josephson junction (flux flow oscillator, FFO) has b een develop ed and successfully tested. The receiver noise temp erature as low as 200 K has b een measured at frequencies of ab out 650 GHz; a p ossibility to phase-lo ck FFO to the reference oscillator has b een demonstrated this is vitally imp ortant for sp ectrometer op eration. To ensure the p ossibility of remote tuning of a phase-lo cked (PL) SIR on the b oard of a ballo on a numb er of approaches for the PL SIR automatic computer control have b een develop ed and tested. New mo difications of the sup erconducting lo cal oscillator (FFO) have b een develop ed, fabricated and tested; an optimization of FFO design for integrated sp ectrometer has b een p erformed. Using a sp ecially develop ed technique FFO linewidth has b een studied at frequencies up . . , . . , . . . 7

to 700 GHz. A free-running linewidth b etween 9 and 2 MHz has b een measured in the frequency range 500 В 700 GHz. As a result the sp ectral ratio of the phased-lo cked FFO varies from 35 to 90 % corresp ondingly. The effect of FFO linewidth imp erfections on retrieval pro cedure of the atmosphere gas sp ectra is discussed.
