Mechanical design stabilisation system type 1: not easy...
1&2
Work in progress: T1 test module
M. Esposito, K. Artoos
Changed from universal joints with flanges to square joints(less space, increased axial stiffness)
Monolith design: advantages not so sure Some solutions to reduce parasitic roll, but increased stresses Solution found to decrease weight without changing stiffness 3 actuator solution studied: good solution but $$$ But possibility to make SiC girder continuous to save money. Integration sensors: inertial reference mass We have to deliver a prototype

Status design Main Beam Quad support: Alignment + stabilisation
Functional performance testing + development time: Study and try assemblyRequires controlled stable environment (Temperature, Vibrations, Access)Demonstration feasibility + ultimate performanceWater cooling + powering magnet
Test module location not adapted for this.
Magnetic measurements and fiducialisation
Installation Test moduleIntegration in test module, connections to other modules, robust show case, transport, …Demonstration alignment and stabilization but not representative for CLIC tunnel
ISR
Proposal: Build two MBQ modules, upgradable
4
For type 1 test module: Freeze some choices, simplifyand start construction drawings.
Construction second set mini CAM movers (+ possibility to implement upgrade)Construction stabilisation support
will be based on Rexroth profiles and aluminium stiffeners
Build second yoke (for test precision machining and assembly) + dummy coils (fast prototyping ?)Test assembly with dummy actuatorsConstruction can be upgraded.Ignore the parasitic roll at the beginning
Real inertial sensors will take longer to be developed with the help of industry

Tentative first planning Type 1
1&2
Test module:Alignment stage test-module, base, pre-alignment stage : two months : end July (t.b.c. by Hélène)Purchase more piezo actuators: ~ 3 monthsStabilisation test module version 1 space holder, dummy actuators: end July
Construction type 1 yoke + dummy coil : still to be estimated
ISR MBQ:Alignment stage cams: to be tested/ calibrated separately , available for ISR installation estimated: End July, interface stabilisation should be ready then as wellStabilisation stage: Ready end August
More detailed planning to be prepared for next meeting + progress reporting
