The CRESST experiment in its first phase is using sapphire detectors with tungsten phase transition thermometers to search for dark matter WIMPs. At present Four 262 g detectors are performing first measurements under low background conditions. Detec

A tungsten superconducting phase transition thermometer on a 32 g sapphire crystal has given an energy resolution of 100 eV (FWHM) for 1.5 keV X-rays, increasing to 440 eV at 14 keV. A possibility to obtain similar resolution in much larger crystals

Small concentrations of long-lived radioisotopes such as 59Ni are not necessarily easy to determine by AMS because of the background of stable isobars, in this case 59Co. The gas-filled Q3D magnetic spectrograph has been successfully used for isobari
