AWAKE spectrometer meeting

→ Europe/Zurich

Spectrometer meeting - 10/11/2016


Present:
Stefano, Thomas (CERN)
Lawrence, Matthew, Michele, Simon (UCL)


Thomas

- See plots.
  - Aluminium only is uniform to 0.5%.
  - With quartz coating uniformity is 2%.
  - Quartz can be more easily cleaned, but will be more affected by radiation (browning).  Al can be easily re-coated, quartz not.  Reflectivity with quartz coating is a few % lower.
    -> Mirror samples in the AWAKE area and will see how they are affected.  Take out at end of run and measure their performance.
    -> For CERN to do coating, would need contribution of ~8000 CHF for 6 mirrors.

Stefano

- Gravity curvatures do not affect mirror perfomance.
- All agreed that Stefano’s simulations and report were complete and that we could proceed with purchasing mirrors as specified in his report.

-> To get a quote for 2, 3, ... per mirror and uncoated or Al coated.

Lawrence

- Presentation in TB next week on backgrounds.
- IEEE paper can be contribution or peer review; will go for peer review.
