Calorimetric low temperature detectors (CLTDs) for heavy ion detection have been demonstrated to achieve an excellent relative energy resolution of ΔE/E=1−2x10−3 in a wide range of energies. Combined with time of flight detectors they were successfully applied in accelerator mass spectroscopy and stopping power measurements. They also have the potential to be applied for determination of fission fragment distributions as well as for mass identification of super heavy elements with Z ≥ 113. At present a CLTD array consisting of eight individually temperature controlled pixels with an active area of 12x6mm2 is used in different applications. To exploit the full potential of CLTDs in further experiments the active area has to be increased. The design of the new array with 25 individually temperature controlled pixels and an active area of 15x15mm2 will be discussed. Results from the first performance tests will be presented.
