MUON DETECTORS: ALIGNMENT / M. Dallavalle
A new Muon misalignment scenario for 2011 (7 TeV) Monte Carlo re-processing was re-leased. The scenario is based on running of standard track-based reference-target algorithm (exactly as in data) using single-muon simulated sample (with the transverse-momentum spectrum matching data). [...]

MUON DETECTORS: DT / Marco Dallavalle
The DT group is undertaking substantial work both for detector maintenance and for detec-tor upgrade. Maintenance interventions on chambers and minicrates require close collaboration between DT, RPC and HO, and are difficult because they depend on the removal of thermal shields and cables on the front and rear of the chambers in order to gain access. [...]

MUON DETECTORS: RPC / Pierluigi Paolucci
In the second part of 2013 the two main activities of the RPC project are the reparation and maintenance of the present system and the construction and installation of the RE4 system. Since the opening of the barrel, repair activities on the gas, high-voltage and electronic systems are being done in parallel, in agreement with the CMS schedule. [...]

MUON DETECTORS: ALIGNMENT / S. Szillasi
The CMS detector has been gradually opened and whenever a wheel became exposed the first operation was the removal of the MABs, the sensor structures of the Hardware Barrel Alignment System. By the last days of June all 36 MABs have arrived at the Alignment Lab at the ISR where, as part of the Alignment Upgrade Project, they are refurbished with new Survey target holders. [...]

TECHNICAL COORDINATION / Austin Ball ; Wolfram Zeuner
  Since the last report, much visible progress has been made, as the LS1 programme approaches the halfway point. From early October, technical and safety shift-crew have been present around the clock, allowing detectors to stay switched on overnight, ensuring that safety systems are operational and instructions for non-expert shift-crew are clear. [...]

MUON DETECTORS: ALIGNMENT / G. Gomez
  A new muon alignment has been produced for 2012 A+B data reconstruction. It uses the latest Tracker alignment and single-muon data samples to align both DTs and CSCs. [...]

MUON DETECTOR / F. Gasparini ; G. Iaselli ; R. Breedon ; T. Rodrigo Anoro
DT Commissioning of the two negative wheels was done on the surface to gain time; YB-1 was completed in June and that of YB-2 on October 3. A new test is ongoing following their lowering into the experiment cavern (UX) [...]

TECHNICAL COORDINATION,SCHEDULE AND INTEGRATION / A. Ball ; W. Zeuner
A pivotal milestone in CMS underground installation will be reached during this CMS week when the 1920 ton central wheel (YB0) of the iron yoke is lowered into the experimental cavern on Wednesday 28 February. This milestone will be reached on the on the date planned due to the hard work and dedication of many people, on the surface, underground and at supporting sites [...]
