3. The MSC-CI section 29/10/2009JPh Tock MSC-CI LHC NC status + cryomagnet coordination (Role to be officialised ?) MB, SSS and IC NCRs status in LHC After last interconnections closure there were still many open NCRs: MB: 215 SSS: 438 IC: 17 The aim of this job is to point out the REAL NCRs that shall be treated during next shutdown, and to CLOSE all solved NCRs.

4. The MSC-CI section 29/10/2009JPh Tock MSC-CI LHC NC status + cryomagnet coordination MB, SSS and IC NCRs status in LHC After a BIG work of sorting and treating, the NCRs still open are as follows: MB: 63 (152 solved) SSS: 55 (383 solved) IC: 4 (13 solved) All the open ones were addressed to concerned colleagues. Most of them are in progress, BUT: 69 (!) need to be closed by CRG. At least 4 reminders were sent (the 1 st one on July 14 th…. ), no reaction at all! ELQA team (Richard Mompo and Giorgio Dangelo) and ICQA team (Christian Scheuerlein) reacted very fast, despite the big pressure they have to perform electrical tests in the tunnel.

22. Triplet Cryostat Particularities Based on, and as far as possible, using LHC Arc Cryostat Components, tooling and methods The cryostat body is well advanced, interface details will be adjusted to suit the interconnects etc. Identical cryostat length and cross-section for all 4 quadrupoles, and the D1 Shorter cryostat components for the CP Some similarities concerning the envelope thermal insulation of the QDSX The MS tooling set will be upgraded (preserving its original function) to be able to cryostat Q1 Q2A Q2B Q3 CP and D1. To be reinstalled in SMI2 after modification Some part of the CNRS dipole tooling may be incorporated eg: the electric winch
