Radiation tests and production test strategy for the ALICE TOF readout upgrade board
The readout board for the ALICE TOF detector named DRM2 is now in the production phase: 88 boards are being produced (72 are needed in the experiment). Since the boardwill operate in a radiation environment (0.13 krad total dose expected in 10 years and a flux of 0.26 KHz/cm$^2$ of hadrons with ener...

Sumario: | The readout board for the ALICE TOF detector named DRM2 is now in the production phase: 88 boards are being produced (72 are needed in the experiment). Since the boardwill operate in a radiation environment (0.13 krad total dose expected in 10 years and a flux of 0.26 KHz/cm$^2$ of hadrons with energy above 20 MeV), a complete irradiation campaign at the component level was performed. In this paper the focus is on the irradiation tests on a Microsemi Igloo2 FPGA and two different types of Avago SFP optical transceivers using a 100 MeV proton beam, available at the facility operated byINFN-TIFPA at the Centro di Protonterapia in Trento. This paper also focuses on the board production test strategy. |
