Calorimetric low temperature detectors (CLTDs) for heavy-ion detection have been frequently demonstrated to achieve an excellent relative energy resolution of ΔE/E = 1-5×10−3 in a wide range of ions and energies. Such detectors were already successfully applied in accelerator mass spectrometry, and have the potential to be applied in superheavy element research where CLTDs as high resolution energy detectors combined with time-of-flight detectors may be used for identification of superheavy nuclei with Z ≥ 113. The CLTDs developed up to now have an active area of approximately 3×3 mm2, not sufficient to fully exploit their potential. To increase the active area, an array of CLTDs for heavy ion research is currently subject of design and investigation. As a first step, a 4×2 pixel prototype array with eight individually temperature controlled pixels and a total active area of 12×6 mm2 was realized and its performance under heavy ion irradiation was investigated. Results from a recent experiment performed with 4.8 MeV/u 132Xe-ions will be presented, and future perspectives will be discussed.
