Energy calibration measurements of MediPix2

Characterization of Medipix2 assemblies with CdTe sensor using synchrotron radiation

“…By differentiating of the threshold scan and attributing the threshold values to the respective energy values, one can obtain energy dependent spectra. [3] The CdTe detector has been processed at the FMF, Freiburg. The CdTe material was delivered by the commercial supplier ACRORAD.…”

A semiconductor radiation imaging pixel detector for space radiation dosimetry

“…The Timepix and related devices produced by the Medipix2 Collaboration are also capable of being configured to measure the properties of the incident neutron flux (Uher et al, 2005;Jakubek et al, 2006Jakubek et al, , 2009Greiffenberg et al, 2009;Vykydal et al, 2006a), but this paper will focus solely on the detection and measurement of incident charged particles. Each detector in use has been individually calibrated pixel-by-pixel to yield an accurate correlation between the TOT counts recorded and the energy deposited in the sensor volume that was responsible for that pixel's response (Fiederle et al, 2008).…”

Energy-discriminative performance of a spectral micro-CT system

“…In Table 3, we listed the estimated selectable threshold values corresponding to the K-edges of the tested materials. Because the relationship between the photon energy and the threshold value is a linear function [13,26,27], it can be approximated by a linear regression from the data in Table 3: E = −0.20 × T + 128.35, where E is photon energy and T is energy threshold (Fig. 4(d)).…”
