Status type 1 MBQ

Part: Status

Base

Prealignment stage

Alignment stage 80-90 % parts received

Interface (fixed to stabilisation stage)

To be designed

Stabilisation stage Concept designs available, construction design to be done

Type 1 MBQ Available

Alignment sensors/Fidu

To be integrated/studied

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
