Improvement of the detection efficiency calibration and homogeneity measurement of Si-SPAD detectors

BACKGROUND Silicon single-photon avalanche diodes (Si-SPADs) are the most used devices for measuring ultra-weak optical radiant fluxes in many quantum technology fields, such as quantum optics, quantum communication, quantum computing, etc. In all these fields, the detection efficiency is the main parameter, which has to be accurately known for achieving reliable measurements. In this paper we ...

Sensor simulation and position calibration for the CMS pixel detector

In this paper a detailed simulation of irradiated pixel sensors was used to investigate the effects of radiation damage on charge sharing and position determination. The simulation implements a model of radiation damage by including two defect levels with opposite charge states and trapping of charge carriers. We show that charge sharing functions extracted from the simulation can be parameteri...

A new multi-detector telescope calibration method

A new calibration method, applicable to multidetector telescopes, is presented. This method is based on the comparison between experimental data and the ones obtained from Monte-Carlo simulation. The method just needs a accurate knowledgment of the detector spectrum. To test the method, data obtained in GANIL accelerator, are used. Obtained results are presented and the method accuracy is concl...

Automatic Calibration of Multi-strip Position-Sensitive Detector

Calibration is the transformation of the output channels of a measuring device into the physical values (energies, times, angles etc.) It is a laborand time-consuming task even if only few detectors are used. However, the situation changes appreciably if the calibration of a multi-detector system is required, where the number of registering devices extends for hundreds [1]. Let us have a look a...

A method for small-animal PET/CT alignment calibration.

Small-animal positron-emission tomography/computed tomography (PET/CT) scanners provide anatomical and molecular imaging, which enables the joint visualization and analysis of both types of data. A proper alignment calibration procedure is essential for small-animal imaging since resolution is much higher than that in human devices. This work presents an alignment phantom and two different cali...
