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 will service this user platform by allowing the allocation of SAXS beamtime directly after SANS measurements so that full advantange of co-location of SAXS and SANS facilities of the PSB 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.
