W. Ootani et al., SENSITIVE GERMANIUM THERMISTORS FOR CRYOGENIC THERMAL DETECTOR OF TOKYO DARK-MATTER SEARCH PROGRAM, Nuclear instruments & methods in physics research. Section A, Accelerators, spectrometers, detectors and associated equipment, 372(3), 1996, pp. 534-538
Sensitive n-type and p-type germanium thermistors were fabricated by t
he melt doping technique and by the neutron transmutation doping (NTD)
technique, respectively, aiming at the use for cryogenic thermal dete
ctor, or bolometer of Tokyo dark matter search programme. We report on
the measurements of the sensitivities of these thermistors. In partic
ular, the p-type thermistors are sensitive enough to scale up our exis
ting prototype LiF bolometer and realize a multiple array of the bolom
eters with the total absorber mass of about 1 kg.
