SEU signature protocol…

TE/CRG technical procedure for SEU signature identification:1) Trend analyzing (20 s reboot)2) AMB Test on TECRGCE test bench3) Manufacture electronic stressing test

In accord with TE/MPE (F. Formenti).

SEU: Balance 2011-2012

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 2nd unit of P8 (Phase III),

additional shielding required?
