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.

Solution

BDI day 2003 8

Radiations damages (102963)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 9

Position signal with no beamPosition 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 10

Loading settingsLoading 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

Remote timing diagnosticRemote timing diagnostic

Already exists but requires expert

Solution has to be implemented for operators

ConclusionsConclusions

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
