Possibility of producing a bulky supersensitive thermal detector at a temperature close to absolute zero
The possibility is discussed of using a large-mass system, cooled to infralow temperatures (< or =1 K) and insulated, as an ultrasensitive detector of energy-releasing interactions with fields and particles. The detectors register the change of the system temperature. The necessary condition for the realization of high sensitivity (10/sup -22/ W/g at T<0.01 K) is a decrease of the inflow of parasitic heat due to mechanical vibrations, to electromagnetic induction, and to the cosmic and natural-radioactivity background. The principal results of an investigation at 1 K are reported. It is observed that the main obstacle to the development of the detector may be the reversible effect of thermal relaxation in the detector material after the cooling.
