The LHC Injection Process: Simulation of Injection Scenario(s)

Thursday 27 Sept 2001, 16:00 → 17:00 Europe/Zurich

SL Auditorium (CERN)

The present longitudinal SPS to LHC injection scenario has been developed in several steps. First, different principal scenarios were studied with a simple program, observing the longitudinal bunch phase space representation but assuming an ideal inflexible RF system; capture with a 200 MHz system revealed necessary to avoid unacceptable beam losses. In reality, due to heavy beam loading in LHC, beam and RF are intimately linked as a complex system, the details of the RF system and its loops playing a decisive role. Therefore a program was developed to simulate the injection with a real RF system. In a first approach bunches, loading the RF cavities, were assumed point like to study the RF system behavior. In the latest version also bunches in full phase space representation can be observed together with the real RF system. Some introductory remarks on longitudinal beam dynamics will be given and the chain of developments towards the presently foreseen scenario will be revealed. Several movies will underline the dynamics of the process.
