Description
We report on the first results of a mortality campaign on the Low Gain Avalanche Detectors (LGAD) produced by Hamamatsu (HPK) as prototypes for the High-Granularity Timing Detector (HGTD) in ATLAS. The study was conducted at the ELI Beamlines site during the ELI RD50 campaign as part of the ELI User Experiment that has been recently selected from the ELI User Call proposals. The HPK-P2 (WF25) sensors from the most recent run production were irradiated with neutrons in the JSI research reactor of TRIGA type in Ljubljana on the four fluences, (4, 8, 15, 25) x 1014neq cm-2, and subjected upon the carefully designed fs-laser based mortality study. The research strategies and applied methodology will be explained, and the results discussed. The preliminary results will be opened to conversation and feedback from the RD50 collaboration. The plans will be discussed too.
