论文摘要
硅传感器是粒子物理学高精度传感器的首选技术。但是,只有最近才能使用内部放大的低噪声硅传感器。所谓的低增益雪崩检测器(LGAD)传感器已开发用于高能物理学的应用,但缺乏测量低能质子(<60 KEV)所需的两个特征:一个薄的入口窗口(按NM的tens顺序)和在传感器表面附近产生的信号的有效放大(在最高下方的1 um下)。在本文中,我们介绍了所谓的质子低增益雪崩检测器(PLGAD)传感器概念,以及传感器第一原型的表征的一些结果。 PLGAD专门设计用于检测低能质子和其他低渗透颗粒。它的检测效率将比非硅技术更高,并且有望比竞争硅技术便宜很多。
Silicon sensors are the go-to technology for high-precision sensors in particle physics. But only recently low-noise silicon sensors with internal amplification became available. The so-called Low Gain Avalanche Detector (LGAD) sensors have been developed for applications in High Energy Physics, but lack two characteristics needed for the measurement of low-energy protons (<60 keV): a thin entrance window (in the order of tens of nm) and the efficient amplification of signals created near the sensor's surface (in a depth below 1 um). In this paper we present the so-called proton Low Gain Avalanche Detector (pLGAD) sensor concept and some results from characterization of the first prototypes of the sensor. The pLGAD is specifically designed to detect low-energy protons, and other low-penetrating particles. It will have a higher detection efficiency than non-silicon technologies, and promises to be a lot cheaper and easier to operate than competing silicon technologies.
