The Faculty of Physics and Applied Computer Science at the AGH University of Science and Technology in Cracow (Poland) invites applications for a 2-year research position at the post-doctoral level to join the efforts dedicated to the Large Hadron electron Collider (LHeC) project at CERN [1].

The experimental High Energy Physics group at the AGH UST has a long tradition of top research in HEP and now is involved in the Atlas and LHCb experiments at CERN as well as in STAR and ZEUS experiments at the BNL and DESY, respectively. Recently, the Polish National Agency for Academic Exchange (https://nawa.gov.pl/en/) funded an opening of the LHeC research at the AGH UST.

The prerequisite development of the LHeC project is the design of a new accelerator to provide intense, high energy electrons for collisions with the protons of the LHC storage ring at one interaction point at the CERN-LHC. Accelerated in a new recirculating energy recovery linac, a 50 GeV electron beam will be brought into collision with one of the 7 TeV proton beams of the LHC while the hadron-hadron data taking at the other LHC experimental points concurrently continue. In the context of the LHeC project, maximum performance of the collider as well as for the data taking of the high energy detector are demanding. Specifically, in ep scattering the control of halo and synchrotron radiation backgrounds through a carefully designed Interaction Region (IR) is of decisive importance [2]. It is based on a highly efficient synchrotron radiation shielding and effective protection of the sensitive detector and machine components. The key issues of this so-called machine detector interface are a solid knowledge of the characteristics of the photons that are emitted during the focusing and bending of the electron beam. A carefully designed system of radiation masks and collimators is needed to protect the particle detector as well as the super conducting magnets of the LHC proton lattice from direct photon hits. The obtained results will directly lead to an optimized IR beam pipe geometry and layout of the inner tracker design as well as of the very forward taggers of the LHeC detector, and of a detector of electron-hadron interactions at the Future Circular Collider (FCC-eh).

The successful candidate will be based at CERN, and will be member of the LHeC study group, collaborating closely with CERN’s accelerator and beam dynamics experts.

Applicants must have (or expect to receive very soon) a PhD in particle or accelerator physics. The position is defined in collaboration with CERN (COAS program) with a foreseen monthly net salary of about 5000 CHF and will include social security benefits (information is available on request). The contract is scheduled to start in March 2023. The AGH UST strive to offer equal opportunities for everyone.
