1. Prototype cavities development
Goal: test in HNOSS of one Double-Spoke prototype cavity equipped with a coupler
Status of cavities
Cavity GIULIETTA stand-by (waiting for CM assembly)
Cavity ROMEA + coupler
Finalisation of the Labview software implementation in the RF loop: DONE
RF conditioning of the 300K: DONE: Pmax=120 kW, 2.86 ms.
Cool down of the cavity: ON GOING
Test plan for the following weeks
W12: RF conditioning of the 4K
W13-14: RF test of the 4K, then 2K.
from Roger yesterday
Dear colleagues,
This morning we have started the cooldown of HNOSS and Romea with liquid helium. By the end of the week we expect to be cold and have the Romea (fundamental) power coupler re-conditioned. Next week we will then start with our testing programme. If you or any of your colleagues are interested to attend (part) of the testing programme you are very welcome. With best regards, Roger.

2. Prototype cryomodule development See Patxi’s presentation

Cavities
First set of drawing sent yesterday (74 drawings to be reviewed).
Technical points still under discussion: bi-metallic joint design for the Helium outlet, annealing of some Ti helium vessel parts (to relieve stresses)
Next video meeting: 24/03/2017
