AWAKE spectrometer meeting

Wednesday 22 Feb 2017, 16:30 → 17:30 Europe/Zurich

CERN

Present: Fearghus, Ishkhan, Lawrence, Matthew, Michele, Simon, Stefano 

 

Welcome to Ishkhan who has joined the CERN-BI group and will work on the spectrometer.

 

Stefano

- Can switch off lights in hall and no safety lights around that area.

  -> Will need to have some enclosure in the camera / mirror 3 area.

- Received filter specs from Lawrence today and can then order once has measurements of size.

- Manufacturer wants to increase mirror thickness to 40 mm.  Price stays same, so we are okay with this.

-> Ishkhan to find out about vibration in the hall.

 

Michele

- Software tests at the beginning of March.

  -> Need 'scope with 500 MHz; ask Stefano if they have a spare and if not get it from CERN pool.

  -> Meet with Lars afternoon on 2/Mar.

- E-mail from Simon on triggering camera ?  Fearghus said that Bart said that Lars should have ordered a trigger cable.

  -> Fearghus / Michele to discuss issue with Lars.

 

Lawrence

- Scintillator screen.

  - Different phosphor gives 25% light yield of previous versions.  So we can test and try it.

  - Also looking at DRZ screens from MCI Optonix screens which should give a high light output.

- BDSIM is now working after the upgrade and so can get back to work on it.

 

Fearghus

- Asked for quote for DRZ screen

- Asked for quote for cooling system from ANDOR company and US manufacturer ($2600)

-> Workpackage description done from his side.  Passed on to Michele as DAQ is out of date.

 

Matthew

To discuss talks at Collaboration Meeting with Edda.  Could have:

- Overall spectrometer status - Fearghus

- Performance and backgrounds - Lawrence

- Camera acquisition - Michele

but may need to compress if not enough time.

 

Many of us will meet at the Collaboration Meeting in Novosibirsk in 2 weeks.
