Revised Planning

First Re-Baselining after C&S Review I US cavities delayed

CERN cavity production (DQW) for SPS is adopted as baseline

Impact on SPS is significant

Cavity String Assembly

26th LARP Hi Lumi Collaboration Meeting - Cryomodule Integration Plans 6

Assembled in SM18 ISO4 Clean Room

9 Cavity string components loaded on

to assembly trolley using manual crane

Components are individually positioned

and aligned

Sequential positioning with respect to

pervious flange

String is closed (aligned in Z direction)

Gate valves closed for Cryomodule
