Abstract

The low-penetrating particles low gain avalanche detector comprises a multi-layered structure and receives particles from a radiation source (13). It consists of a thin entry region that receives the particles from the radiation source (13); a low-penetrating particles detection region, with a p++ shallow field stop (1), positioned beneath the entry region, and a p absorption layer (3), positioned beneath the p++ shallow field stop (1), and an n multiplication layer (4); and a high-penetrating particles detection region positioned beneath the n multiplication layer (4), consisting of a n-- silicon substrate (5). Due to the chosen doping polarities, the primary electrons (created by the particles from the radiation source (13)) drift away from the entry region. That way, signals from low-penetrating particles or radiation experience amplification, while the noise is kept similar to a conventional PIN structure, thus increasing the signal-to-noise ratio.
