| Popis: | We present the results of germanium and silicon ionization detectors tests at 20–100 mK. Such devices allow for particle identification when used in coincidence with bolometric detection in particular for dark matter search. We obtained 1.7 keV (FWHM) resolutions for 10–100 keV X-rays on 4–10 mm thick germanium and 3 mm thick silicon pin diodes. We also studied the performances of a “solid ionization chamber” with evaporated aluminium electrodes. We focused our attention on the carriers trapping which alter the detector performances |
