The preliminary results of the recent RRR measurements will then be presented. Then\, together with the limits presented from talk no. 2\, the probability of an incident will be presented for beam energies be tween 3.5 and 5TeV. The available methods at our disposal for addressing the limiting factors and operating at a higher energy will then be reviewe d: a complete circuit qualification method coined the Thermal Amplifier c an define the maximum safe energy of the LHC in case of a quench next to a defective joint. Ways of avoiding magnet quenches\, another critical elem ent of the analysis\, for instance by optimizing BLM settings will then be shown. Finally\, a proposal of a strategy for running at the highest poss ible energy compatible with a pre-defined level of risk will be presented. As a case study\, the method will also be applied on the training campaig n of sector 56\, where a significant number of quenches at currents above 10\,000A were seen with no adverse effects. Were we simply lucky with this training campaign?\n\nhttp://indico.cern.ch/contributionDisplay.py?contri bId=58&sessionId=3&confId=103957 LOCATION:Chamonix URL:http://indico.cern.ch/contributionDisplay.py?contribId=58&sessionId=3& confId=103957 END:VEVENT BEGIN:VEVENT SUMMARY:The LHC RF System: plans for the next long shutdown DTSTART;VALUE=DATE-TIME:20110125T082000Z DTEND;VALUE=DATE-TIME:20110125T083500Z DTSTAMP;VALUE=DATE-TIME:20130523T051031Z UID:indico-contribution-103957-30@cern.ch DESCRIPTION:Speakers: BRUNNER\, Olivier (CERN)\nThe potential limitations for future running of the LHC RF systems are presented.

With Linac4 and exploiting the beam of all four PSB rings to fill most of the PS circumference allows bringing the PS close to the direct space charge limit with one injection. Batch compres sion after acceleration to an appropriate intermediate energy allows incre asing the beam brightness at the price of reducing slightly the number of bunches per PS batch. Potential beam characteristics at PS ejection have b een estimated\, with and without an increase of the PSB to PS transfer ene rgy\, and with a single or a double batch injection. The impact of shorter bunch trains on the downstream accelerators has also been analyzed. These new schemes are presented together with their expected benefits.

On the other hand\, the first commis sioning experience has also provided first indications of system limitatio ns alongside of hints for possible improvements. In particular\, the expec ted performance limitations from losses in the cold dispersion suppressors (DSs) at either side of the warm cleaning insertions have been confirmed. While improvements of the system will already be implemented during the 2 010 shutdown\, the major performance limitation from the DS require a chan ge of the machine layout that will be addresses in the 2012 long shutdown. In this papers\, the proposed improvements of the system are presented. T he expected gains and the implication of the proposed changes on the syste m re-commissioning are discussed.\n\nhttp://indico.cern.ch/contributionDis play.py?contribId=45&sessionId=4&confId=103957 LOCATION:Chamonix URL:http://indico.cern.ch/contributionDisplay.py?contribId=45&sessionId=4& confId=103957 END:VEVENT BEGIN:VEVENT SUMMARY:Cryomagnets\, Interconnections\, Superconducting Circuits: What to do in 2012/13 if you are not consolidating splices ?

It’s thus time having a first look on the observed radiation levels around LHC critical areas and to compare them to available simulation results. In spite of the still very low inte grated intensities and cumulative luminosities\, we will try revisiting th e failure rate predictions by looking at both the observed early failures\ , as well as the additional results from 2010 CNRAD tests. Upcoming possib ly in early 2011\, electron cloud and scrubbing issues and their impact on radiation levels will also be briefly discussed. Updated predictions for 2011 operation and beyond will be deduced\, on the base of the envisaged L HC intensity\, energy and luminosity reach. Starting from these estimates\ , priorities for short-term improvements and beam tests are discussed\, as well as a brief overview of upcoming R2E driven mitigation actions.\n\nht tp://indico.cern.ch/contributionDisplay.py?contribId=43&sessionId=4&confId =103957 LOCATION:Chamonix URL:http://indico.cern.ch/contributionDisplay.py?contribId=43&sessionId=4& confId=103957 END:VEVENT BEGIN:VEVENT SUMMARY:Which systems (except main circuits) should be commissioned/tested for 7TeV operation before the long shutdown?

In particular\, it shields the super-conducting magnets against heating from beam loss. Its performance is characterized by the leakage rate or cleanin g inefficiency. The system inefficiency depends on the beam energy\, the b eam type (protons or ions)\, the collimator settings and operational imper fections. The achieved performance during the first full LHC run is presen ted. Operational tolerances and difficulties during the 2010 run are revie wed. Setup procedures are described and ways for faster setup discussed. B ased on the observed loss rates and magnet quench limits future performanc e is extrapolated\, in particular for the achievable store beam energy and beta*. Observations and updated limits are compared to previous predictio ns. Collimator settings for 2011 are proposed and associated limits and ma rgins explained.

No machine protection issues were recorded\, and the reliabili ty of the machine protection system (MPS) did not impact beam operation in a significant way. After an initial phase of low intensity beam operation that was used among other things for the commissioning of the MPS\, the i ntensity was increased in steps of a factor 2 up to 2 MJ. Following a stab ility run at 2 MJ\, the intensity was increased in steps of around 3 MJs e very few days during train operation. The intensity steps and upcoming MP issues were approved and discussed in the restricted Machine Protection Pa nel (MPPr) composed of representatives from the main MP sub-systems. Two r eviews of the MPS were organized in 2010\, one internal and one external r eview.

During the s queeze\, delicate optics manipulations take place when the stored energy i s maximum. Ramp and squeeze were commissioned rapidly and smoothly became operational.

After having cumulated a full y ear of experience and having gained important feedback on the machine beha viour and on the operational procedures\, it is now time to address effici ency optimization while still respecting safe boundaries. In this paper\, the experience with ramp and squeeze is reviewed\, possible bottlenecks ar e identified and paths for improvements of the nominal LHC cycle are addre ssed.

Above 3.5 TeV\, the currents become sufficiently large to burn a defective joint\, and for safety one therefore has to rely on non-quenching the joints.
