Applying for beamtime

User Club

The ILL User Club provides online access to all the information and administrative tools for our scientific visitors, presented in a user friendly environment.

Block Allocation Groups

In order to enable biology groups applying for time at ILL to make most efficient use of their beamtime, a Block Allocation scheme has been introduced for SANS experiments on D22.

Block Allocation Group (BAG) proposals can be submitted by groups of at least three teams (maximum of eight), preferably including teams with previous ILL experience. Each BAG should have a nominated coordinator. New proposing teams may contact Anne Martel at ILL for advice on how to form a BAG.

The subcommittee may add or remove groups, or change the size of the block allocations. Note that the Scientific Council Biology Subcommittee may also suggest regrouping new proposals with an existing BAG. The scheduling of BAG beamtime is grouped, allowing greater flexibility in the choice of projects and samples to be studied at a given time.

BAG proposals will be evaluated for one-year period (two scheduling periods); they can be renewed for another term (additional one year) through the normal proposal procedure.

However, experimental progress reports are requested before the Scientific Council meetings every six months.

Submitting a proposal to be included in a BAG

Please use the standard Electronic Proposal Submission system once logged into the Visitors Club (https://userclub.ill.eu/cvng). Please state in the scientific case that you wish to part of a BAG - please contact the College Secretary if you wish to have more information about existing BAGs. Include the coordinator in your list of proposers.

Requests for test time of a few hours to help develop future experiments can also be part of your scientific case.

BAG Coordinators
Please note that BAG coordinators should email a list of proposals in their BAG (using this template) to the Chair or College Secretary before the relevant Subcommittee Meeting.

Reimbursement rules
An ILL BAG travel budget will be allocated according to number of days scheduled for member country projects. Users are welcome to make as many visits to ILL as necessary provided their home laboratories contribute to travel if the ILL BAG travel budget is overspent.
