X-γ ray spectra of 241Am acquired with the SiC detector operated at 27 °C and 100 °C, respectively. Noise levels of 415 eV FWHM at 27 °C and 1 keV FWHM at 100 °C have been measured. The energy resolution is limited by the front-end silicon JFET, expecially at 100 °C. The detector is biased at 200 Volts.
