Beam Time

General information

The infrastructure provides 30 weeks of beam time per year for external users who want to carry out DESIREE storage ring experiments. See below for instructions on how to apply and submit a beam time proposal. The proposal submission deadlines are April 30 and October 30 for experiments to be carried out Sep-Dec and Jan-Jun, respectively. The proposals will be evaluated by external reviewers.

The infrastructure offers theoretical/computational support to users that have been granted beam time. More information can be found here. 

Note: There is no charge for carrying out experiments at the infrastructure, but the infrastructure does not provide any financial support to its users (e.g. for travel expenses).

Instructions and template

Users are strongly advised to contact the DESIREE team by sending an email to before submitting a beam time proposal (at least one week before the deadline). That is to ensure that the proposed experiments are feasible to carry out at the DESIREE infrastructure within the next beam time period. Proposals that are judged infeasible will not be sent to the DESIREE proposal reviewers for evaluation.

The template (in docx- and rtf-format or as LaTeX source) that should be used for preparing the beam time proposal can be found here.


Deadlines: April 30th & October 30th


Please send the beam-time proposal (in pdf-format) by email to
