Abstract
Highly granular calorimeters play a crucial role in the precision QED measurement, one of the most important parts of the calorimeter being the sensor. In 2022, two samples of silicon pad sensors and two samples of GaAs sensors were tested in a 5 GeV electron beam at DESY. A technological prototype has been developed to demonstrate the performance of the ECAL sensors. For the readout, a very low-power ASIC called FLAME was used. The raw data is pre-processed and deconvoluted using FPGAs. This article describes the results of the test beam measurements, together with a study of the edge effect and homogeneity of the sensor response.
期刊介绍：
Section A of Nuclear Instruments and Methods in Physics Research publishes papers on design, manufacturing and performance of scientific instruments with an emphasis on large scale facilities. This includes the development of particle accelerators, ion sources, beam transport systems and target arrangements as well as the use of secondary phenomena such as synchrotron radiation and free electron lasers. It also includes all types of instrumentation for the detection and spectrometry of radiations from high energy processes and nuclear decays, as well as instrumentation for experiments at nuclear reactors. Specialized electronics for nuclear and other types of spectrometry as well as computerization of measurements and control systems in this area also find their place in the A section.
Theoretical as well as experimental papers are accepted.
