RADIO SPECTROSCOPE ON GAS CELL Russian patent published in 1995 - IPC

FIELD: quantum electronics. SUBSTANCE: radio spectroscope on gas cell has magnetic screen, coil for creation of magnetic field, heat insulating chamber housing spectral lamp, filter and resonator with heater, temperature transducer, photodetector and gas cell. Resonator is inserted with two metal plates. Gas cell is mounted in resonator between two metal plates in thermal contact with the latter. SHF diode is located between one of plates and surface of resonator. Distance between them is not less than 3 mm. Gas cell has volume 0.8-1.2 qu. cm, is manufactured from alkali-resistant glass and is filled with rubidium in the amount of 0.005-0.02 mg. EFFECT: increased sensitivity. 2 cl, 1 dwg
