Problems: a) Strip Detector Requires 8 Coupling Capacitors with Size of 10 x 4 x 5 mm b) Certain Distance between the Crystal and the Bonding Plate (3 mm) c) Detector Enclosure and the Cold Stage of the Preamplifier d) Detector Stack Cooling – PA 1.2 W <Power< 1.2 W + Radiative Heating 1.2 W ?

d) Flexibility to Fit to Various Setup Configurations e) Separate Vacuum Space for the Dewar, Cold Finger and Detector Head

Options:a) Pixel Drift Detector (Disadvantage – Higher Operational Voltage)

b) Alternative Cooling – He, Ne, X-Cooler II
