Mating 200kV chamber with existing Prep, Bake and NEG lines media:170602_HV_IP.pptx

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

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

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
