Intro:
- keep adding material to the spreadsheet
- also note the new tab for the e-beam only case
Maryna:
- added beampipe
- w/o bp + Kapton: signal comes from the air mostly
- w/ bp + Kapton: small signal but still larger than the bkg (too low stat)
- w/ bp + Tungsten foil (10 um): large signal again, small background
—> this is possible since we don’t need to terminate the vacuum in the bp case…
- make the w/o beampipe tab in the spreadsheet
- results for phase2
- need to understand why there are edge-like structures —> a priori we don’t expect these in this xi
Arka:
- showing the impact of manually removing the large sources of background (vacuum chamber exit window)
- check if in slide 7 the 2 strips on the top left plot are due to the stave fixations
- cut is sensible since the LANEX+Cherenkov were optimised
- for both setups, some bkg also comes from the joint between the vacuum chamber and the beampipe
- showing first results from the e-bam only for the e+laser setup
- 5 keV in 25 um of
