Energy spectra of a 55 Fe source, measured at room temperature (left) with 0.25μs shaping time and at -10°C (right) with 1μs shaping time. The longer shaping time used at -10°C is used thanks to the reduced leakage current (see also Fig. 4).
Fig. 5. ENC curve of the 30 mm 2 SDD measured at different temperatures. In this figure the shaping time range to be used with two different scintillators, due to their decay times, are also shown. Fig. 6. Graph of the Quantum Efficiency η measured with the 30 mm 2 SDD detector, with custom and standard anti-reflection coatings. Fig. 7. Picture of the circular SDD coupled to the LaBr 3:Ce module. The detector is placed on a ceramic substrate for biasing and signal extraction. 2x10 6 2x10 4 137 Cs spectrum 661.7 keV 6x10 4 661.7 keV 1x10 6 4x10 4 2.7% FWHM escape 5x10 5 32 keV Ba X-rays 0 200 400 600 E [k V] 600 650 700 Energy [keV]
