摘要：
Energy-dispersive detectors for photons and alpha particles have recently been built. They are based on designs for infrared bolometric detectors working at liquid helium temperatures. For 5. 5 Mev alpha particles the energy resolution (fwhm) has been published to be better than 35 keV in preliminary experiments, but thermodynamic limits to the resolution were calculated to be of the order of a few tens of ev. In the present paper limitations to the resolution caused by fluctuations in the processes converting particle energy to heat in the detectors are calculated.
