The Resonance Ionisation Laser Ion Source (RILIS), ISOLDE’s principal ion source, is being consolidated after over 30 years of operation. The laboratory housing the laser installation has been dismantled and is being rebuild with a larger footprint and improved safety. With ISOLDE aiming to deliver beams again in summer of 2028 to its user community of >1000 scientists from across the world, we are looking for an experienced person who will help us to reinstall the laser system and recommission it for ion beam generation.

Your responsibilities

• Install the lasers as well as the required hard- and software to operate the RILIS on a 24/7 basis with automated laser beam stabilisation and monitoring.
• Test the new pump lasers.
• Develop new resonance ionisation schemes, targeted at moving RILIS into a fully solid-state laser laboratory.
• Document the laser system, creating a detailed operational requirement specification.
• Participate in set up and operation of the laser ion source including on-call operational duties.

Be sure to meet the eligibility criteria

• You are a national of a CERN Member State or Associate Member State. Currently, we cannot consider applications from Pakistani, Lithuanian, Latvian, Cypriot, Croatian and Turkish nationals, as the ceiling defined under Article II.5 of the Associate Membership Agreement has been reached.
