John, Hugh, Bubba and I agreed on path toward installation of the SEI support tubes, bellows and table. Please see list below. 1. Remove septum at HAM3/Inspect for identified leak/-Apollo-Cleanroom in place/Kyle worked on this yesterday 2. Test septum at HAM5/6-Kyle-Cleanroom in place 3. Move ion pump from HAM5 to HAM6-Kyle-Cleanroom in place/Kyle worked on this yesterday 4. Install all possible feedthroughs on BSC1/2/3 and HAM4/5/6; blank off as needed-Apollo-Appropriate purge needed/Hugh is working on this 5. Install support tubes, support table and bellows per E980268 at HAM6-SEI/Apollo-Cleanroom in place 6. Pump down and leak check volume-Kyle/Gerardo/John-No cleanroom needed
We plan to leak check between step 4 and 5 in order to avoid any ambiguity when testing the support tube bellows. So there will be two pump down/leak test cycles.
If leaks are found there may be additional pump/test cycles.
