Modification to Log-Ampposition measurement in TT2-TT10 BDI day 2003 T Bogey AB/BDI-EM
Outline • TTPOS principle • Recall of problems • Solutions implemented in 2003 • Things to be done for 2004 • Conclusions BDI day 2003

Principle BDI day 2003
Recall of problems • Auto trigger BMU10T • Position • Lead ions (stripped) • Radiation damage (102963) • Position signal with no beam • Loading settings when SSC changes • Remote diagnostics BDI day 2003
Auto trigger BMU10Twith lead ions (stripped) • 2002: Auto trigger works with Pb53+ (unstripped) but does not work with Pb82+ (stripped) • 2003: A new electronics for the auto trigger module solved the problem. BDI day 2003
Autotrigger position for BMU10T • 2003 BMU10T • Problem 1013 1015 1019 1020 1023 1024 1025 1027 1029 1030 • 2004 • Solution BDI day 2003
Radiations damages (102963) • The monitor is very close to the dump • During 2002 run ~ 23 E+3 gray on the electronics module • We moved the electronics away from the BPM • No more radiation damage during 2003 (but still a problem on the vertical plane) BDI day 2003
Position signal with no beam • Without beam Log-Amp still gives an output signal • No information of intensity • Autotrigger module gives a hardware interrupt to validate the data • A software algorithm check the data BDI day 2003
Loading settings • When SSC changes MCR have to call experts to load settings • Stephen Jackson has implemented an option on the PCR Operational Software - BI applications web page to help operation • For a new SSC specialist still needed BDI day 2003
Remote timing diagnostic • Already exists but requires expert • Solution has to be implemented for operators BDI day 2003
Conclusions • TT2/10 experience helps us for TT40/41 CNGS electronics • Each Log-Amp will have its own autotrigger • Position and Intensity available • Possibility to use the same electronics in TT2/10 upgrade BDI day 2003
