Timing and gain performance of Teledyne e2v's LGADs before and after irradiation

LGAD devices from Teledyne e2v (a long-established commercial manufacturer of scientific imaging sensors) have been fully characterised before and after irradiation. Irradiations were performed with 27 MeV protons at the MC40 cyclotron in Birmingham to deliver a fluence from 5.6 × 1013 up to 8.3 × 1014 1 MeV neq/cm2 to seven LGADs. Te2v LGADs were shown to exhibit the expected trends in breakdown voltage, gain and time resolution as seen in literature. Time resolution and gain performance before and after irradiation are reported here and compared with published results for other manufacturers of such devices.
