380 GeV Klystron design compatible with upgrades. Double tunnel or single tunnel required.
Tunnel Optimisation Tool kick off meeting to be held on the 22nd of May
Civil Drawings are to be produced by Civil Draughtsmen - new drawings to be produced for the Klystron design and existing drive beam design drawings to be changed.
Next meeting on the 21st of July.
TO BE CONFIRMED WITH DANIEL
CEIS Working Group Meeting 16/06/2017 – Matthew Stuart & John Osborne

47. Low energy Klystron Klystron Layout
Double tunnel – one for the accelerator and one for the klystrons.
Accelerator tunnel How does this change?
Are the connections between the tunnels compatible with the current design?
ID of the accelerator to be 5.6m not 3m
Klystron tunnel – 4.5m ID
Section through tunnels
Which Caverns will be required?
Waveguide connections
Klystron Tunnel
Accelerator tunnel – How has the layout changed
Accelerator tunnel – 5.6m ID
Access for second tunnel?
TOT for double tunnel?
Surface buildings for Klystron machine remain the same except no drive beam requires
No turnarounds for initial stage?
