14:00 → 14:05 Current set-up

Use an arm with the optical fibre "mounted" above the detector hole.
Card board as shielding.

14:05 → 14:10 30ns exposure, with not completely working laser

30 ns pulses, ToT distribution is strange looking.
Outside spot centre is the average ToT decreasing, i.e the ToT depends on the deistance from centre.
the countrate is however the same.

14:15 → 14:20 Strange observation

fToA count number 15 seems to always be the preferred output value, no synchronization and different phaseshift from the current pulse generator.

14:20 → 14:30 Next steps

1st Step: Get the pulse generator:
- Name?
- Budget code? -- 33103

2nd Step: Set up and test

3rd Step: .... Approach final setup?

Other things to do:
- Read up for RD50.
- Other tasks?

• CERN can't sign NTNU's standard agreement.
• I'm contacting NTNU to find a way to solve this.
• How have you solved this before?
