Abstract
CZT drift strip detectors with Planar Transverse
Field (PTF) configuration are suitable for high energy astrophysics
instrumentation, where high efficiency, high energy and
position resolution are required from the sensors. We report on
experimental investigations on the DTU Space developed CZT
drift detector operated in PTF configuration with the purpose of
demonstrating that the good energy resolution of the CZT drift
detector can be combined with the high efficiency of the PTF
configuration. A CZT drift strip detector (10 mm x 10 mm x
2.5 mm) was characterized in PTF configuration at European
Synchrotron Radiation Facility (ESRF) using ID 15A beam with
its very fine collimations (beam spot size typically of 50μm and
energies up to 500 keV). The depth resolution is measured
to be 100μm FWHM @150keV and 200μm FWHM@500keV.
These are well agree with the theoretical values. With these
measurements, we demonstrated to achieve high efficiency due
to large effective thickness, high energy resolution due to small
electron drift lengths and sub mm position resolution using depth
information using CZT drift strip detectors with N+1 readout
channels in PTF configuration.
