(13/08/2011) P8 stop SEU signature..

(27/08/2012) P4 SEU signature… Rebooting (20s)…

SEU signature protocol… TE/CRG technical procedure for SEU signature identification: 1) Trend analyzing(20 s reboot) 2) AMB Test on TECRGCE test bench 3) Manufacture electronic stressing test In accord with TE/MPE (F. Formenti). TECRGCE M.PEZZETTI

SEU: Balance END CRG/OA-as

SEU: Balance Number of weeks with Stable Beam > 640 bunches: ~23 weeks ~15 weeks TS CRG/OA-as 640 bunches TS Courtesy A. Suraci TE-CRG-OA

SEU: Balance Actions taken to improve robustness : CV891: automatic reset implemented into PLC (action: cut off 24 Vdc). TT89x: modification of electronics card (capacitor removed), timer PLC: moved into better protected zone (P4-P6-P8 caverns) 24 Vdc: longer term, to be moved into a safer protected zone and better distribution of power consumption to be done. AMB (Magnetic bearing controlers): relocation 2 nd unit of P8 (Phase III), additional shielding required? CRG/OA-as Courtesy A. Suraci TE-CRG-OA
