Agenda

Present:

Before the review we need to have numbers for radiation shielding with new scattering chamber design
- Then make sure to go over with Alan to check for any show-stoppers
- Potential dates for the review is around early October
We need to have a collaboration meeting before the review
- The preferred dates are Aug 24th and half-a-day on 25th
- The backup dates are Sep. 18th and 19th
The other high priority issue is the Q1 collimator compatibility between PREX and CREX - Bob
- We would like to run CREX with PREX collimator to see compatibility
Add the collimator containment boxes to top and bottom of the collimator box. - Rakitha
- If we ended up using the same collimator for both experiments, the top box will hold the collimator move mechanism and the bottom one will eventually safely secure the collimator for disposal.
- If we need two collimators then they will be made as single unit one top of the other.
We also need to choose the material for the collimator box, now that collimator is well shielded for disposal, activation from the collimator box will be contributing factor.
- The interface between collimator box and septum + acceptance tubes needs to be properly designed if they are two different materials.
Since the collimator box will be a new design we still have some room to optimize it's size. - Rakitha, Kent, KK and engineering
- This can only be done with engineering input

It would be nice to have real-time viewer for optics studies in commissioning (disussed in 01/16/2014 meeting)
