Abstract

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 27MeV protons at the MC40 cyclotron in Birmingham to deliver a fluence from 5.6 × 10¹³ up to 8.3 × 10¹⁴ 1MeVn_eq/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.
