Applied Physicist (Radiation Environment)
Are you a physicist with some experience in the radiation environment of experiments? Join our team and take a leading role in characterizing the very challenging radiation conditions of the LHCb experiment. Participate in the operation and maintenance of its sub-detectors and contribute to developing them, taking into account these essential radiation aspects! Take part!
Applied Physicist (Radiation Environment) in the Experimental Physics (EP) Department, LHCb Coordinators Office (LBO) Group, Detectors Operation (DO) Section.
You will join:
The Experimental Physics (EP) Department that carries out basic research in the field of experimental particle physics. It aims at providing a stimulating scientific atmosphere and is an important reference centre for the particle and nuclear physics community at large. It contributes to the education and training of young scientists.
The LHCb experiment, one of the four large experiments at the LHC at CERN. The experiment is specialised in investigating the tiny difference between matter and anti-matter and searching for hints of new physics. The LHCb experiment has been taking data for several years and a major upgrade of its detector is being prepared which will be installed in 2019/2020.
The LHCb Detectors Operation section in the Coordinators Office Group (LBO-DO) that is responsible for the support of the detectors' design, installation and operation as well as decommissioning. The group also liaises with other groups in EP and other departments at CERN to provide general infrastructures and services to the experiment and ensure its safe operation and maintenance in accordance to CERN safety rules and regulations.
As an Applied Physicist with expertise in Radiation Environment in the LBO-DO Section, you will provide the assessment of the radiation environment of the LHCb experiment both in its current running conditions and for future upgrades. The knowledge of this aspect of the experiment is essential for the technology choices to be carried out for several sub-systems as well as the planning of installation, maintenance and decommissioning of the experiment with strong implications on the reliability of the detector and safety of personnel.
You will ensure necessary studies and measurements will be carried out and work closely with the project leaders so that such information is properly taken into account in the construction and operation of the LHCb experiment over the next years.
Carry out simulation of both prompt and residual radiation levels for the upgrades of the LHCb experiment.
Monitor prompt radiation levels in the LHCb cavern during operation and determine the evolution of the existing system for the LHCb upgrade.
Ensure that coherent up-to-date information on radiation levels is provided to all LHCb sub-systems.
Contribute to the determination of the amount of radioactive material to be handled in the next Long Shutdown as well as the radiological environment and the amount of radioactive material expected from operation of the LHCb upgrade.
Fulfil the role of Radiation Protection Expert assuming responsibility for the organization of low-risk regular activities in the experiment in collaboration with the relevant CERN safety groups.
Support the Technical Coordination team, taking an active role in safety activity, in particular working closely with the LHCb Radiation Safety Officer to address in the safety procedures for the LHCb Upgrade the radiological risk according to the ALARA principle.
PHD/Doctorate in the field of physics, or equivalent.
