[Pansophy] Mircea: VTA test results D5 HH-R031/HE-R094/HE-R135 8 May 2024

[Mircea Stirbet]

Good morning John,

Do not understand why these two travelers have no data... once I have the data processing, I filled up the travelers, and if needed generate the NCR... the NCR is based on Performance limit, I just copy what I have written in this box and paste in the NCR.

This morning, for HE-R135 the performance is empty
[cid:0a5d0789-1d1b-4b7f-bd22-dca0b65a550c]
But.. the NCR 613 has text input on 9 May 2024:
[cid:e2cd787d-cdc1-4564-a709-db7fa98ec3cb]
Something related  with Pansophy ?!

Had , as requested updated data for the two travelers:

Take care,
Mircea

Mircea,



Could you please fill out the corresponding travelers below. I accidentally closed the one for HE-R031 but already asked the Pansophy-team to reopen it for you.





Cheers,

John V

Good afternoon,



D5, TS34-002 had low vacuum readings up to the right angle valve (about 2.5e-5 mbar). Usually this value is one or two orders of magnitude higher.

  1.  HE-R031 (Pos1) quench limited at 16.7 MV/m. No FE onset up to Emax.

  1.  HE-R094 (Pos2) radiation onset at low cavity gradient (6-7 MV/m). Qo drop bellow HE project specification at 19.5 MV/m

  1.  HE-R135 (Pos3). In the morning, measured all passbands  frequency  with the Network Analyzer. However, was not able to find the lock frequency during attempted high RF power tests. Suspect lambda leak.



D5 has enough liquid for more testing. This afternoon, Peter will have a look on HE-R135.  Thanks Peter!



See attached screen copies for HE-R031 and HE-R094.



Mircea
