CDR Status information

• Much good progress by the authors since last meeting• Today’s (08-July 2011) state:

47 contributions needed40 received - 23 as draft only

- 17 as “final” submission• http://project-clic-cdr.web.cern.ch/project-CLIC-CDR• Can reasonably expect 4 more (draft) contributions in July.• IEB (Internal Editorial board) relaunched.• Only “received” contributions are compiled into the draft CDR.

We wish to get 5...10 authors, who convert in July their draft into a submission.• Most things agreed for the front-page layout. All volumes will have similar

appearance. Details (=matter of taste) still to be discussed.• Collection of CDR “signatories” through a web-page will

be tested in August and will be active for the period September-November

• Expect final document in time for December 2011 Council.

Test modules : last results

• Repeatibility in the installation of cWPS sensors on their interfaces: < 1 μm

• Repeatibility in the installation of inclinometers on their interfaces : < 2 μrad

Installation & validation of alignment systems

Validation of linear actuators on 1 DOF test bench (M. Sosin)

• Maximum backlash: 4 μm

• Repeatability < 1.5 μm

• Resolution < 0.2 μm

MB quad mock-up (with cam movers)

• Measurements concerning Eigen frequencies of the interface plate took place last Tuesday & Wednesday

• Pre-alignment sensors to be installed this Friday

• First tests concerning resolution over the whole range & 5DOF will take place next week

• Design under progress concerning a smaller cam mover (for module type 1)

Mock-up installed in 927

Geodesy studies

In collaboration with ETHZ, a deflectometer was installed in 839 (12 m long)

Deflectometer: relative measurements of deflection of vertical in tunnel

First results show that inclinometer installed is not adapted and will be replaced

MDI

• Good progress on 3 D anti-solenoid simulations• Progress on stabilization (CERN and SYMME)• Progress on muon background simulations• First parts of QD0 prototype are at CERN (next slide)
