Job Description

Your responsibilities

In this position, you will have the opportunity to join a joint collaborative team from the Technologies department  and the Beam department. This will enable you work together with the Operation Crews of the accelerators as well as Equipment Experts.

AccTesting is the software framework used at CERN to perform the commissioning of the LHC superconducting magnets, electrical circuits and their protection equipments. It implements the automation, scheduling and systematization of the commissioning procedures. As the experiences with it were positive, the use of AccTesting will be expanded other accelerator systems and to the entire accelerator injection chain, spreading to all accelerators at CERN.

Your tasks will be:

• Extend the AccTesting framework to support all accelerator systems for automated test execution and analysis; 
• Renovate the way the services are deployed to scale it to the entire accelerator complex;
• Define requirements with operators and equipment experts.

About us

At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. Using the world's largest and most complex scientific instruments, they study the basic constituents of matter - fundamental particles that are made to collide together at close to the speed of light. The process gives physicists clues about how particles interact, and provides insights into the fundamental laws of nature. Find out more on http://home.cern.
