27. Commissioning the LHC Physics Programme

Emmanuel Tsesmelis (TS/LEA)

25/01/2006, 09:00

All experiments will have installed their detector set-ups and will be ready for commissioning with beam at the start of LHC operation. The physics programme is expected to be rich even at the projected initial luminosities. This paper presents the requirements and expectations of the experiments for single beams, early collisions, the pilot physics run, the heavy-ion run and the...

69. Aspects of machine induced background in the LHC experiments

Gloria Corti (CERN)

25/01/2006, 09:20

In our report we review different aspects of the LHC Machine Induced Background and its implication on the specific experiments. On the base of current assumptions and estimates of the various parameters of the problem, we will present a few examples of the effect of this background on the experiments' detectors. Using the present understanding of the background sources and its...

70. Bringing the first LHC beams into collision at all 4 IP's

Enrico Bravin (AB/BDI)

25/01/2006, 09:45

Collision rate monitors are essential in bringing particle beams into collision and optimizing the performances of a collider. In the case of LHC the relative luminosity will be monitored by measuring the flux of small angle neutral particles produced in the collisions. The LHC rate monitors (BRAN) are being developed by Berkeley National Laboratory (USA) in the framework of the LARP...

68. The Solenoids and Dipole magnets of LHC experiments

Werner Herr (CERN AB/ABP)

25/01/2006, 10:10

The LHC experiments are equipped with solenoids or spectrometer magnets. Both types affect the beam dynamics or constrain the choice of the optical configurations. The implications are estimated and possible limitations are discussed. The present working scenario is presented and its flexibility is subjected to a critical assessment.

61. Beam Dump and Injection Inhibits

Jorg Wenninger (CERN)

25/01/2006, 11:00

This presentation describes the proposed beam interlocking strategy for the LHC experiments and for the experimental magnets. Two different types of interlocks are foreseen: beam dump requests and beam injection inhibits. The interfaces to the LHC beam and injection interlock systems are described. Proposals for implementations and open points are presented.

77. Beam Condition Monitoring and Radiation Damage Concerns of the Experiments

Alick Macpherson (Rutgers University/CERN)

25/01/2006, 11:25

From the very start of LHC operations, the experiments will have a strong interest in monitoring online the beam conditions and radiation levels in and around the experimental areas. Although the equipment in these caverns is designed to tolerate the expected radiation levels in normal operation, such monitoring is seen as key to protecting the detectors from damage due to unexpected...

66. Experimental equipment interacting with beam operation

Daniela Macina (CERN)

25/01/2006, 11:50

The operation of the experimental magnets and movable devices (TOTEM/ATLAS Roman Pots, LHCb VELO, ALICE ZDC, LHCf calorimeters) will interfere with beam operation. Their operation has been discussed during the last year and the main conclusions are reviewed together with the remaining open issues. Details on the communication foreseen between the CCC and the experiments' Control Rooms...
