This proposal seeks time on BM29 to allow joint SAXS and SANS measurements to be carried out as part of the PSB SAXS/SANS platform. The BAG services this user-platform by allowing the allocation of SAXS beamtime in connection to SANS measurements so that full advantage of co-location of SAXS and SANS facilities on the EPN can be provided to users. The scientific case for each joint request is evaluated by the ILL review committees of its Scientific Council and the allocation of time for successful proposals coordinated between the ILL and ESRF user offices.
