Comprehensive technology study of radiation hard LGADs

Towards radiation tolerant sensors for pico-second timing, several dopants are explored. Using a common mask, CNM produced LGADs with boron, boron + carbon and gallium gain layers are studied, under neutron and proton irradiation. With fluences ranging from 1014 to 6 × 1015 neq/cm2 on both particle...

description Towards radiation tolerant sensors for pico-second timing, several dopants are explored. Using a common mask, CNM produced LGADs with boron, boron + carbon and gallium gain layers are studied, under neutron and proton irradiation. With fluences ranging from 1014 to 6 × 1015 neq/cm2 on both particle species, results focus on acceptor removal, gain reduction via electrical characterization, timing performance and charge collection. An emphasis is placed on stability via dark rate and operating voltage studies.

Using a common mask, CNM produced LGADs with boron, boron + carbon and gallium implanted gain layers are studied under neutron and proton irradiation. With fluences ranging from $10^{14}$ to $6\times 10^{15} n_{eq}/cm^{2}$ on both particle species, reported results focus on acceptor removal and gain reduction via electrical characterization. Timing performance, charge collection, gain and relative efficiency are treated through charged particle measurements, including signal analysis and noise characterization. An accent is placed on stability, via dark rate and operating voltage studies while, radiation related gain reduction mechanisms are examined comparing gain estimations through different approaches.arXiv:2111.06731oai:cds.cern.ch:27907392022
