phase2 ME design meeting minutes 4_14_2021
Danny, Shaun, Gary, Grames, Marcy, Poelker, Reza, Alicia
Gary presented a "vacuum tight" layout, nice
- wider girder, based on phase1 experience, although there won't be as many pumps hanging from side
- that said, we want ion pump connected to side of dif pump can, rather than below (less chance of ion pump growing a whisker when mounted to side. This is a busy region, need to visit tunnel to make sure the side-mounted ion pump won't interfere with anything
- green solenoid downstream of chopper2 cavity:
- water lines oriented other way?
- get with Neil and feel confident the old solenoid can be removed (I assume we cut off 2.75" flange, slide solenoid off)
- Danny points out, we can't have flanges inside bore of green solenoid, imagine a custom nipple with bellows, welded to chopper cavity pipe...
- green solenoids include option to water-cool but we won't need cooling for 200 keV beam
- replace ion pumps on today's model with those used for phase1, 25 L/s pumps with pump out port
- Mount pumps "beam right"
- Decide YAG vs Chromox view screens
- make three more antenna style BPMs
