Summer 2017 SAD Update
200kV Gun
- Task and Timeline Gantt chart => media:170421_CHG.pdf
- Installing HV chamber
- Jim Dahlberg earmarking last week June, or first week July for as-found of HV chamber, will account minor diff w/ X/Y/PITCH/YAW w/ table
- Mating 200kV chamber with existing Prep, Bake and NEG lines media:170602_HV_IP.pptx
NEG Tube
- We are making 4 BPM's
- ...Shop has materials now and machining (#327755)
- ...then Phil will pick up for weld, 400C bake, leak check, clean, NEG coat
- ...then Pete will perform optical/electrical checks
- ...then John will perform Gabou map
- We are making 1 solenoid NEG tube
- ...MMF prep and magnet new MFH to +/- 2.5A
- ...then Phil will vacuum fire 4.5" NR + 2.5" pipe
- ...then shop will weld flanges w/solenoid on tube
- ...then Phil will clean/leak check
- ...then Phil will NEG coat
- Final NEG tube design => media:NEGTUBE_MAY03.pdf
- M20 Old Assembly Modification media:0990.pdf
- M20 New Assembly Can media:0991.pdf
- M20 New Assembly 6.00 x 4.500 reducer flangemedia:0.992.pdf
- Assembly of compound NEG tube
- Attach BPM #1 to Solenoid tube (axially symmetric)
- Rotate BPM #2 to align to BPM #1 and attach to Solenoid tube
- Now, the BPM #1 + Solenoid + BPM #2 is one piece
- Install compound NEG tube by aligning BPM #1/BPM #2 upright, use upstream ROT to Gun2 bellows flange and
Diagnostics Chamber Installation
- Second bake and activate week of May 30th => Remove and replace Gun3 ATLIS task
- Once Marcy/Phil give OK on 3I vacuum => John, you can remove VBV3I02 from special interlock and swap PLC for relays
