3. Single Jaw Thermal Test
Thermocouples measure temperature distribution
Reference bar, water cooled to maintain straightness (radiation shield ?)
Standoffs fix jaw distance to reference bar at center
Capacitive proximity sensors at ends
Flexible end mounts
Orientation: may be rotated 90o, or 180o or on end
2 x 5 kW heaters, coupled with thermal grease

4. Single Jaw Thermal Test
Purpose: measure cooling effectiveness and thermal deformations
Internal helical cooling channels
Jaw not rotatable
Central aperture stop with flexible jaw end supports
Commercial electric resistance heaters, coupled with thermal grease
SS power ~10 kW, evenly distributed
No transient testing
FE model test => validation of simulations
Water connections by conventional mechanical fittings
Tank purged with inert gas to protect the copper jaw (?)
Machine strain-relief grooves and re-test

5. RC1 Mechanical Prototype
FY06
RC1 consists of jaws, tank & actuators - evaluated for horizontal (shown), vertical (90o) and skew (+/- 45o) orientations.
FY07, RC2
Variant: use CERN vac tank, dummy jaws of correct weight
LARP LHC PHASE II COLL REVIEW – RC1 CONSTRUCT & TEST - E. Doyle 15 Dec No 5 /10

6. RC1 Mechanical Prototype
Purpose: bench top testing of the jaw actuating mechanism in all necessary orientations
lidded vacuum tank for easy access
Need CERN adjustment mechanism - no support stand for RC1
Realistic cooling water feed-throughs and flexible connections
no realistic connections to external world: no beam pipe aperture in tank, ad-hoc access to tank for cooling tubes, ad-hoc jaw aperture and rotation control, ad-hoc instrumentation connections for position, temperature, etc.
RC2 will incorporate LHC-compliant interfaces
Probably not possible to apply heat loading
Variant: use dummy jaws of correct weight => use actual CERN vacuum tank (modify: removable cover)
Use CERN Phase I components to the max extent possible
