SE-Service Equipment SE volume (LxWxH)

Max. distance SE – ME

Comments

Plasma Cell Power for heating (~10kW), vacuum, water cooling, misc. power for diagnostics and controls

Half an rack Few meters May require 360V, 3-phase connection

Laser for seeding ~10kW electrical power, temperature stabilization and clean room (+/- 0.5C for T:sapph), quiet EM environment

Power supplies1x3x1m3

Few meters Fiber laser may be simpler and the only option for CNGS

Mirrors Motorization, remote/feedback, tip/tilt 1-2 instruments in racks (~20cm)

Few meters 10-20 m upstream from plasma entrance

Plasma diagnostics None expected Take light out through optical fibers

RF-gun RF-klystron 20m

Laser for gun

Sec. beam diagnostics

OTR foil (few mum-thick Ti) in p+ beam path in vacuum tube + OTR system to collect light

1x1m2 on optical table (added to 3.6x1.2 table?)

Take light out through optical fibers to streak camera located where permanent access is possibleExtra size optical table?

Information available & missing

• For the West Area site, integration depends on the extraction line geometry chosen. An older option (trench in TT5) is shown, but any other option will not cause major modifications or show-stoppers on CDR level.

• The layouts shown further-on use all the information that we have available, but a lot of information is still missing. We urgently need more input from the collaboration for each element: footprint, services (power, cooling, gas, cables etc.), “geometrical” constraints…

West Area: Issues

• Trench in conflict with technical galleries at 450 GeV beam (see Chiara’s & John’s talks)

• Magnet storage in TT4/TT5• No beamline installed, needs new magnets• Needs new proton dump, radiation issues (see

Helmut’s talk)• Interference with nTOF (shielding, access)• But: easy access to experimental facility

CNGS: modeling

• 3D civil engineering tunnel model available. Keep end of beam line as for CNGS (tunnel&beam slopes 5.66% to Gran Sasso)

• Still to do: Combine 3D civil engineering model and 2D installation drawings (see what can stay, what must go)

CNGS: Issues

• Linked to CNGS future plans, only first stage Awake can be planned for the moment (leave rest in place)

• Radioactive area: interventions are more complex • Underground area: limited space available, civil

engineering & access procedures are more complex• But: proton dump available, some recuperation of

magnets possible, access independent from LHC/SPS, fairly new services already installed


25

From Edda’s talk:West Area vs CNGS – Incomplete!

E. Gschwendtner, AWAKE Collaboration Meeting, CERN, 18/10/2012

West Area CNGSProton beam line - To be done + Most of it exists

Prompt dose issues(muon dose)

- Consequences on beam energy and/or limited number of extractions!

+ OK, under control

Other radiation issues - Shielding to protect West Area - Target, horns! Need long cool-down

Civil engineering - Needed for trench -+ to be checked whether needed.

Size of experimental area + OK - Small

Access - New access system, + but experimental area nearby

+ Access system exists, - but long distance to experimental area

Electricity - A lot must be refurbished, renewed + Exists, - needs some modifications

Cooling, ventilation - A lot must be refurbished, renewed,… + Exists, - needs some modifications

Storage - TT4/TT5 full with stored magnets, etc… area needed in LS1. build new storage building.

+ No storage area

Beam dump - Must be newly built, - lot of shielding needed + Exists

… … …

Also More Information Needed!!
