Description

The results are presented for the gamma and neutron irradiation tests for SFP+ transceivers. The radiation tolerance of the electronics components used in the detector area is a key of the electronics systems at the LHC experiments. For example, the total ionising dose and the 1-MeV neutron equivalent flux estimated for the frontend electronics of the thin gap chamber of the ATLAS experiment are 14 Gy and 4 x 10^11 cm^-2 for an integrated luminosity of 4000 fb^-1. We tested several types of SFP+ transceivers from Broadcom and Finisar. Gamma ray was irradiated up to O(100) Gy at the Cobalt-60 facility of Nagoya University. Neutrons were irradiated up to O(10^12) cm^-2 using the tandem accelerator at Kobe University. The results can be referred to in designing the systems and selecting the SFP+ transceivers for the upgrades of the LHC experiments.
