Nanosecond Speed in Dual Threshold X-Ray Photon Counter
Voxtel strives to enable the world’s best next-generation opto-electronics systems, and the best systems start with the best research. To address the X-ray science community’s need for advanced X-ray detectors that can rapidly process scattered X-ray signals, we are developing a dual threshold X-ray photon counting detector (DT-XPC). Under SBIR Phase II funding from the Department of Energy, a Voxtel-led team designed and fabricated a dual-threshold X-ray photon counting ROIC that was confirmed to support the 10-MHz and 100-MHz count rates of the latest generation of X-ray synchrotron sources, like the accelerator at Argonne National Laboratory’s Advanced Photo Source. Senior CMOS Imager and Readout Design Engineer Jehyuk Rhee presented the team’s findings on October 29th local time at the 2013 Institute of Electrical and Electronics Engineers Nuclear Science Symposium and Medical Imaging Conference & Workshop on Room-Temperature Semiconductor X-Ray and Gamma-Ray Devices (2013 IEEE NSS/MIC/RTSD) in Seoul, Korea.
