A hadron collider with a centre-of-mass collision energy of about 100 TeV and a proton-proton luminosity of 5 1034 cm-2 s-1, permitting operation with both proton and ion beams would be the next big step forward in particle physics at the high-energy frontier. In this context, the EuroCirCol conceptual design study was launched by a collaboration of institutes and universities worldwide, among which the Laboratoire de l’Accélérateur Linéaire (LAL) at Orsay. This EC supported project is part of the Future Circular Collider (FCC) study, pursued under European leadership and federating resources worldwide to assess the merits of different post-LHC accelerator scenarios. A new research infrastructure of such scale critically depends on the feasibility of several key technologies pushed beyond the current state of the art. Innovative designs for accelerator magnets to achieve high-quality fields up to 16 T and for a cryogenic beam vacuum system to cope with unprecedented synchrotron radiation power are required. The effects of colliding two 50 TeV beams must be mastered to meet the physics research requirements. Advanced energy efficiency, reliability and cost effectiveness are key factors to build and operate such an accelerator.
Efficient beam collimation is one of the critical components requiring special attention. The FCC-hh collimation system must both keep the beam induced energy deposition in the arc magnets below an acceptable level, to avoid quenches of the superconducting magnets, and protect the experiments from machine-induced backgrounds, while keeping impedances within acceptable limits. The LAL Accelerator Department will in the context of the EurCirCol conceptual design study focus on the evaluation of the FCC hadron beam collimation system. The post-doctoral fellow to be recruited at LAL will be expected to work closely with partner groups at IPNO at Orsay, IRFU at Saclay, JAI in the UK and CERN to simulate the efficiency and performance of the proposed collimators, aiming at optimising this system with respect to minimising detector backgrounds and local loss rates in the arc magnets. The team at LAL will need to liaise efficiently with several international groups working on the optical lattice and machine detector interface, including studies of background sources from beam-beam interactions, and the collimators themselves, concerning their impedance, as well as safety and sustainability issues.
Practical details:
The position is funded for two years by the EuroCirCol EU project, with the possibility of renewal for one additional year. The possible starting date is from October 2015. Monthly gross salary will be between €2575 and €2971 depending on the candidate postdoctoral experience (giving a take-home pay before income tax ranging between €2070 and €2389). The fellow will be based at LAL (Orsay, France), with some travel within laboratories taking part in the FCC collaboration, especially CERN.
