14. DSS LV OPFCs test • 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

15. T1 services rack on HF platform • 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 testedon –side, +side. TIG meeting, 10 February 2011

16. ¼ T1 DCS and DSS systems • 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 1st plane internal and 1 on 5th 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

TIG meeting, 10 February 2011

19. Joint test CMS and TOTEM (T1 and T2) • 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 TIG meeting, 10 February 2011

20. 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.

21. Conclusions We are ready. Thank you for your attention. TIG meeting, 10 February 2011
