7.3kfps Readout Solution for 65k Pixel X-Ray Camera Working in Zero Dead-Time Mode

A. Kozioł, P. Maj (AGH Univ. of Science and Techn., Poland)

We present the FPGA implementation of the zero dead-time mode operation for the Ultra Fast X-Ray Camera. The camera consists of two UFXC32k chips bump-bonded to a single silicon sensor incorporated in a stand-alone camera communicating with an external system via Ethernet or Camera Link interface. Commercially available controller sbRIO 9651 including Zynq FPGA was used for both chip communication and Camera Link data streaming. Single software platform used for FPGA, Linux RT and Windows programming allows for efficient memory utilization and a high functionality operation in single-clock cycle in FPGA target as well as a multithread RT application in a state-machine paradigm. Presented solution allows for 7.3 kfps – the fastest framerate among commercial single photon counting x-ray cameras.
