Abstract
1,130,564. Atomic resonance. VARIAN ASSOCIATES. 1 Oct., 1965 [5 Oct., 1964 (2)], No. 8033/68. Divided out of 1,130,563. Heading G6P. [Also in Division H1] In an atomic resonance apparatus including, an assemblage of gaseous atoms in a cavity resonator the cavity resonator is so constructed, dimensioned and arranged that its resonance frequency varies with temperature in a sense opposite to that in which the resonance frequency of the atoms varies with temperature. A rubidium maser comprises a cavity resonator having a hollow cylindrical stainless steel main body 21 containing Rb<SP>87</SP> and filled with a nitrogen buffer gas. The cavity is closed at one end by closing plate assembly 22 which includes a sealing membrane 24 which is deformable to tune the cavity. The other end wall of the cavity is defined by a perforated plate 26 which is transparent to pumping radiation from a Rb<SP>87</SP> lamp (not shown) and the main body 21 is sealed off by glass window 27. A hollow cylindrical envelope 32 is arranged as shown to displace Rb<SP>87</SP> gas which would occupy the space between window 27 and plate 26 and absorb the pumping radiation. In order to make the frequency of the maser insensitive to changes in temperature of the environment the temperature coefficient of the cavity resonator is arranged to be opposite to that of the buffer gas, nitrogen so that they compensate each other providing a stable frequency of the maser, Fig. 3 (not shown).
