The collaboration is to renew for the next years. 1 test per month?

PSI – Irradiated boards and cables

PSI – Irradiated boards and cables

The amount of boards and cables from previous irradiation start to become significant

Use a label on the DUT and on the cables to identify

Equipment Group/Responsible contact Date of the test

Specify if you want to recuperate or throw it away (once the activation levels are low). The material is under your responsibility

PSI - Note on Profibus controller

Anybus IC. Tested at PSI to implement the data communication from an acquisition board to a PLC

ASIC does not stand radiation (overcurrent consumption as soon as beam is on)

Work-around IP core for FPGA could be bought Use of ModBus. Require a rad tol RS485

transceiver. Good candidate?

CEA – 1 MeV facility Request of beam time for 2013 to be sent by

next week Test is advised for equipment in DS LHC areas

and SPS Passive test can be an option Send your request by specifying the

components and the location A brief communication is appreciated if you do

not consider such a test

Beam slots in October/ November

TID test for the future Use of external facility under

consideration GIF++. Dedicated source at

CERN Foreseen for the experiments Negotiations to get test slots and

have a Co60 source

News on NanoFip purchase Ordered 2 batches of 5000

A3P400-PQG208 each Batch 1 (non programmed)

expected on 03.09.2012 Batch 2 (programmed and marked

with logo) expected on 26.11.2012 ~10 components per batch will be

tested at PSI
