摘要
比萨国际核研究所（INFN Pisa）一直致力于优化低压（低至 100 毫巴）气体检测器。MICROMEGAS 技术具有可调节的雪崩体积，本质上适合这些条件。然而，最初的标准模拟预测在这些压力下增益较低。利用 X 射线源进行的广泛测试活动以及根据实验结果进行的改进模拟，使我们对探测器在不同气体压力下的性能有了更好的了解。
The operational principles of MICROMEGAS gas detectors at low pressure: A comprehensive exploration
Extensive efforts at INFN Pisa have focused on optimizing a gas detector for low pressures down to 100 mbar. MICROMEGAS technology, with its tunable avalanche volume, is inherently suited for these conditions. However initial standard simulations predicted low gain at these pressures. An extensive test campaign with X-ray sources and refined simulations based on experimental results have provided a better understanding of the detector’s performance across different gas pressures.
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.
