Paper Abstract

The kinestatic charge detector (KCD) built and researched at the University of Tennessee, Memphis, is now being studied as a possible dual-energy x-ray imager. The present study aims at quantifying the change in the arrival time spectrum (ATS) as a function of the detector's depth, i.e., in the x-ray direction. We measured the change in the full width at half maximum (FWHM) along the x-ray direction in the chamber using a segmented signal- collector board. The FWHM of the ionic signal exhibit a dependence on the x-ray beam intensity, and electric field strength. Furthermore, the average arrival time is almost constant along the detector depth.
