چکیده

Six years before the scheduled commissioning of the LHC at CERN, the basic list of beam instruments has been established. This early date is needed due to the impact of the mechanical design of some detectors (mainly the beam position detectors) on the cryogenic part of the machine as well as for other projects due to the long R&D period (emittance measurements, tune and chromaticity diagnostics and control). This paper gives a detailed overview of the basic requirements and specifications of all beam instruments foreseen for transfer lines and main rings [1].

Lhc Beam Stability and Performance of the Q/q’ Diagnostic Instrumentation

The BBQ tune (Q) and chromaticity (Q’) diagnostic systems played a crucial role during the LHC commissioning while establishing circulating beam and first ramps. Early on, they allowed to identify issues such as residual tune stability, beam spectrum interferences and beam-beam effects – all of which may impact beam life-times and thus are being addressed in view of nominal LHC operation. This ...

Beam Instrumentation and Diagnostics for the LHC Upgrade

The extensive array of beam instrumentation with which the LHC is equipped, has played a major role in its commissioning, rapid intensity ramp-up and safe and reliable operation. High Luminosity LHC (HL-LHC) brings with it a number of new challenges in terms of beam instrumentation that will be discussed in this chapter. The beam loss system will need significant upgrades in order to be able to...

Initial Results from Beam Commissioning of the Lhc Beam Dump System

Initial commissioning of the LHC beam dump system with beam took place in August and September 2008. The preparation, setting-up and the tests performed are described together with results of the extractions of beam into the dump lines. Analysis of the first detailed aperture measurements of the extraction channels and kicker performance derived from dilution sweep shapes are presented. The per...

The LHC as a Nucleus-Nucleus Collider

This paper begins with a summary of the status of the Large Hadron Collider at CERN, including the lead-ion injector chain and the plans for the first phases of commissioning and operation with colliding proton beams. In a later phase, the LHC will collide lead nuclei at centre-of-mass energies of 5.5 TeV per colliding nucleon pair. This leap to 28 times beyond what is presently accessible will...
