Calorimetric low temperature detectors (CLTD’s) for heavy-ion detection provide, as compared to conventional ionisation detectors, due to their detection principle, substantial advantages in detector performance, such as energy resolution and linearity, etc. The absence of any pulse height defect makes them an ideal tool for detection of low energetic heavy ions. CLTD’s have been frequently demonstrated to achieve an excellent relative energy resolution of ΔE/E = 1-2×10−3 in a wide range of ions and energies. The combination of CLTD’s as high resolution energy detectors with time-of-flight (ToF) detectors provides a detector system for high resolution mass identification of low energetic heavy ions. Possible applications are, among others, the mass identification of superheavy elements, of heavy fission products, or of reaction products in experiments with radioactive beams. Recent experiments with an array of 8 CLTD-pixels with a total active area of 12×6 mm2 combined with a ToF-detector have shown a mass resolution of Δm (FWHM) = 1.3 amu for 238U-ions in an energy range of 65 - 150 MeV. These and other results from experiments with various ions and energies will be presented and discussed.
