Detection of single particles and quanta with a cryogenic calorimeter of high mass
Abstract
A status report is given on the development of a cryogenic particle detector. The elementary excitations are transitions between the two states of a Kramers doublet with a Zeeman splitting of the order of 10(superscript -7) eV. Results are given for a compound detector with a mass of 120 grams. The baseline energy resolution is 8 eV rms/(root) Hz, and it is shown that this resolution could be achieved with a very high absorber mass too. The signal rise time depends strongly on temperature, with the shortest signals found at the lowest temperature (35 ms at 30 mK). In addition a much shorter signal with 1 ms rise time can be superposed.
