SAFETY
/ C. Schaefer and N. Dupont
“Safety is the highest priority”: this statement from CERN is endorsed by the CMS management. An interpretation of this statement may bring you to the conclusion that you should stop working in order to avoid risks. [...]

UPGRADES
/ D. Contardo and J. Spalding
LS1 and Phase 1 The detector projects targeting LS1 are progressing well, and a fully integrated schedule developed by Technical Coordination includes installation milestones and a detailed work-plan. The first chambers of the RPC system were produced and are being qualified. [...]

PHYSICS
/ C. Hill
The period since the last CMS bulletin has seen the end of proton collisions at a centre-of-mass energy 8 TeV, a successful proton-lead collision run at 5 TeV/nucleon, as well as a “reference” proton run at 2.76 TeV. With these final LHC Run 1 datasets in hand, CMS Physics Analysis Groups have been busy analysing these data in preparation for the winter conferences. [...]

RUN COORDINATION
/ G. Rakness.
After three years of running, in February 2013 the era of sub-10-TeV LHC collisions drew to an end. Recall, the 2012 run had been extended by about three months to achieve the full complement of high-energy and heavy-ion physics goals prior to the start of Long Shutdown 1 (LS1), which is now underway [...]

DAQ
/ J. Hegeman
The DAQ2 system for post-LS1 is a re-implementation of the central DAQ event data flow with the capability to read-out the majority of legacy back-end sub-detector electronics FEDs, as well as the new MicroTCA-based back-end electronics (see for example the previous (December 2012) issue of the CMS bulletin). A further upgrade in the DAQ and Trigger is the development of the new TCDS, outlined in the forthcoming Level-1 Trigger Upgrade TDR. [...]

TRIGGER
/ R. Arcidiacono ; A. Avetisyan ; A. Bocci ; G Christopher ; A. Perrotta and M. Vander Donckt.
In 2013 the Trigger Studies Group (TSG) has been restructured in three sub-groups: STEAM, for the development of new HLT menus and monitoring their performance; STORM, for the development of HLT tools, code and actual configurations; and FOG, responsible for the online operations of the High Level Trigger. The Strategy for Trigger Evolution And Monitoring (STEAM) group is responsible for Trigger Menu development, path timing, trigger performance studies coordination, HLT offline DQM as well as HLT release, menu and conditions validation – in collaboration and with the technical support of the PdmV group.

MUON DETECTORS: ALIGNMENT
/ Z. Szillasi and G. Gomez.
When CMS is opened up, major components of the Link and Barrel Alignment systems will be removed. This operation, besides allowing for maintenance of the detector underneath, is needed for making interventions that will reinforce the alignment measurements and make the operation of the alignment system more reliable.

MUON DETECTORS: RPC
/ P. Paolucci
In 2013 the main activities of the RPC project are: maintenance and repair of the present system, RE4 chambers installation, and commissioning and upgrade of the online and offline software. About 25 FTE are working on the three items since January and will continue until the end of 2014. [...]
