T1 minus side

Minus side prepared for installation during Christmas

Installed on 10th January 2011

2 quarters moved from H8 to IP5 on 16th Dec. 2010 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.

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

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

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.
