The measured 57Co spectrum for the CZT A detector at a bias voltage of 2200 V. The spectrum was measured using the slow PSHA with ST = 9 µs. The Co γ-ray lines (122.1 and 136.5 keV), the W K X-ray lines (Kα1 = 59.3 keV, Kβ1 = 67.2 keV), the Cd–Te escape lines related to the 122.1 keV line (Cd Kα escape = 98.9 keV, Cd Kβ escape = 96 keV, Te Kα escape = 93.6 keV) and the Cd–Te escape lines related to the 59.3 keV line (Cd Kα escape = 36.1 keV, Cd Kβ escape = 33.2 keV, Te Kα escape = 31.8 keV) are clearly visible. |
