Abstract
A CdTe detector equipped with Timepix can work in both counting mode and time over threshold (TOT) mode. When it works in TOT mode, the count recorded in each pixel represents the amount of collected charge. TOT mode provides an easy and direct way to measure the spectra of sources. A pixelated detector in TOT mode also makes it possible to observe and analyze charge sharing between pixels. The energy calibration of detector working in TOT mode is usually performed under the assumption that an isolated pixel with a nonzero count is free from charge sharing. We studied the calibration procedure on our detector which has a relatively small 55μm pixel size. The results showed that the energies of peaks of the spectra after calibration were constantly bigger than expected. We believed that it was caused by the fact that the charge sharing is not negligible for the isolated pixels when the pixel size is small.
