Saverio MINUTOLI2 T1 detector in H8 TIG meeting, 10 February 2011

Saverio MINUTOLI T1 minus side  Minus side prepared for installation during Christmas  Installed on 10 th January 2011  2 quarters moved from H8 to IP5 on 16 th Dec  Moved to –HF platform on 2 risers, in the next days  Preliminary mechanical test  Temporary connections to the services –DAQ, LV, HV, DCS, DSS, Gas, Cooling  DAQ Readout and Slow Control test  Water leak detection cable installed. 3TIG meeting, 10 February 2011

Saverio MINUTOLI T1 minus side  Insertion of the two quarters, one by one –CSC and BP clearances verification and adjustment –Frames and CMS envelope clearances verification and adj. –Truss position checked and aligned after survey.  Both quarters inserted into CMS endcaps  No interference of T1 on the alignement lasers  Gas and cooling connections  Cabling and grounding with final cables.  DAQ Readout and Slow Control test  Cabling off  - HF platform moved to 4 risers  Final cabling and readout test 4TIG meeting, 10 February 2011

Saverio MINUTOLI DSS LV OPFCs test 14  Each T1 quarter is powered independently. 4 electro-mechanic breakers installed Tested and deployed within DSS. Electrical drawing updated OPFCs AC input and DC output tested 385V DC connections tested on both sides (rack and platform). TIG meeting, 10 February 2011

Saverio MINUTOLI T1 services rack on HF platform 15 4 minirack installed on HF platform Safety smoke detector and Thermostat installed and tested (DSS) All cables from the Counting Room traced and tested Cooling circuit tested on –side, +side. TIG meeting, 10 February 2011

Saverio MINUTOLI ¼ T1 DCS and DSS systems 16  DCS system 3 PT100 temperature sensors installed and checked 2 on electronic boards and 1 on cooling plate 2 active Radiation Monitor sensors installed and checked 1 on 1 st plane internal and 1 on 5 th plane external On the adjacent quarter the RadMon sensors are located on the same plane but opposite sides.  DSS system 2 PT100 temperature sensors installed and checked 2 on electronic boards.  2 passive Radiation Monitor sensors installed TIG meeting, 10 February 2011

Saverio MINUTOLI Joint test CMS and TOTEM (T1 and T2) 19TIG meeting, 10 February 2011  tested only T1 (10 Jan 2011) with CMS CSC ON, without problem  tested T1 and T2 (3-4 Feb 2011) with almost all CMS apparatus ON, without problem. –PIX, TK, ES (Preshower): out –RPC masked some towers in the trigger (to keep the rate within reason) –ECAL masked one trigger tower (ditto) –CASTOR HV OFF (due to miscommunication and sorted out later) and ON later

Saverio MINUTOLI Effect of B on T1 position  Position checks during ramp to 3.8T  Small (order 1mm total) movements recorded on sensors “axial”(YE2 vs YE3) and “radial”(detectors vs vacuum chamber).  Very good correlation and +/- symmetry of displacements indicates that variation is due to the deformation of the end caps with B.
