Brief

The article examines the use of microchannel-plate (MCP) detectors in x-ray framing cameras, which are frequently deployed in laser plasma experiments. The authors calibrate the detectors with short and long pulse x-ray irradiation, as well as with deep UV laser irradiation.

Summary

The article "Gain Uniformity, Linearity, Saturation and Depletion in Gated Microchannel-Plate X-Ray Framing Cameras," published in 1994, examines the performance of gated microchannel-plate (MCP) detectors used in X-ray framing cameras. The authors, O. L. Landen, P. M. Bell, J. A. Oertel, J. J. Satariano, and D. K. Bradley, explore various aspects of these detectors, including gain uniformity, linearity, saturation, and depletion. The article presents calibration results, models for gain saturation and depletion, and discusses the practical implications of their findings. The authors find that while gain depletion is generally negligible for unsaturated data, it can impact image quality when some frames are heavily saturated, particularly in multi-frame X-ray imaging.
