Calibration methods for charge integrating detectors

نویسندگان

چکیده

Since the introduction of extremely intense X-ray free electron lasers, need for low noise, high dynamic range and potentially fast charge integrating detectors has increased significantly. Among all problems that research development groups have to face in such detectors, their calibration represents one most challenging collaboration between detector user is fundamental importance. The main challenge develop a suite capable test over wide range, with granularity very linearity, together certain radiation tolerance possibility well define timings synchronization detector. Practical considerations also be made like calibrate reasonable time, availability source at experimental place so on. Such often not represented by single but several sources can cover different parts cross calibrated final curve. In this respect an essential part mathematical model allows calibrating entire taking into account features are and/or specific. aim contribution compare AGIPD using as internal current source, backside pulsing, IR pulsed laser, LED light mono-energetic protons. procedure used will discussed great detail showing how take few shortcomings (like pixel coupling) common many detectors. This work been carried out frame project European Free Electron Laser.

Calibration procedures for charge-coupled device x-ray detectors

Calibration procedures are described for use with electronic x-ray detectors, with an emphasis on detectors based on fiber-optically coupled charge-coupled devices. Methods are detailed for removing spurious events, pixel pedestals, dark-current, spatial distortion, and intensity response variations for both small-angle and wide-angle applications. The accuracy of the calibration procedures is ...

Calibration and post-processing for photon-integrating pixel array detectors

We have developed calibration and data processing techniques optimized specifically for photon-integrating pixel array detectors (PADs). Primary effects to be calibrated are pixel gain variation and pixel area variation. Gain variations originate in pixel electronics and may be corrected for via a multiplicative factor. In contrast, area variations result from doping inhomogeneities in the sens...

New approach for calibration of pixelated scintillation detectors of intraoperative gamma cameras

Introduction:SURGEOSIGHT is a dedicated intra-operative hand-held gamma camera designed and manufactured by our team to be used for lymphoscintigraphy. Although conventional gamma cameras are widely used, they lack the capability of the sentinel lymph node (SLN) imaging in the operation room. Like conventional gamma cameras it is necessary to calibrate SURGEOSIGHT for linearity...
