Post-Doctoral Fellowship in Physics of Very Slow Neutrons

The main objective of this position is to advance the field of physics with very slow neutrons with a focus on development of instrumentation for production of Very Cold Neutrons (VCNs) and experiments on production and storage of Ultra Cold Neutrons (UCNs). It includes a contribution to the European project CREMLINplus with the main mission to connect Russian and European large-scale research infrastructures, wherein ILL is member of a collaborative effort with the goal to develop a prototype of a VCN source. This source, based on novel moderation materials surrounded by a VCN reflector, is to be demonstrated in experiments with neutrons. In addition, new concepts of UCN storage are to be explored experimentally, with direct impact on various UCN flagship experiments and potentially enabling new scientific projects. The successful candidate will also co-advice PhD students and research interns in their scientific projects on these and closely related topics.

Duties:
Working within our Nuclear Particles Physics (NPP) group, your research program will be focused on:

• Contributing to an ongoing development of a demonstrator for VCN production, based on a new cryogenic device for cooling moderator materials to below 1.5 K.

• Preparing and performing experiments on VCN production and transport using the new device at ILL’s neutron beam facilities, analysing the data obtained from these experiments.

• Contributing to ongoing investigations of novel materials and developments of new methods and tools for production of VCNs and UCNs.

• Co-advising PhD students.

• Publishing the results from the experimental works.
