|General User Proposals (GUPs)|
|Tuesday, 01 June 2010 09:36|
General Users are granted beam time through a peer review proposal process. They may use beamlines and endstations provided by the ALS or the Participating Research Team (PRT) that operates the beamline.
Before Submitting a Proposal
Submitting a Proposal
Log in to ALSHub to submit a General User Proposal (GUP)
Maintaining an Active Proposal
General User Proposals (GUPs) generally remain active for two years (four cycles) or until the number of shifts recommended by the Proposal Study Panels (PSP) for the life of the proposal have been used. Users may decide whether to submit a new proposal or make a beam time request on an active proposal based on the cutoff score for that beamline.
Please note that proposal scores may be adjusted in subsequent cycles, as follows
Proposal Review and Scoring Process
All submitted proposals are reviewed by:
GUPs are scored on a scale of one to five, where one is the highest score. Beam time is then assigned based on each proposal's ranking in relation to all other proposals for a given beamline. Proposals for oversubscribed beamlines may be moved to alternative beamlines with appropriate capability. See proposal score statistics for the current cycle.
Once all proposals have been reviewed and assigned a score, beam time for general users is allocated by the ALS User Office in consultation with the beamline scientist. This process is overseen by the ALS Deputy Division Director for Science. The available beam time is allocated according to the rank order of score, beginning with the best score and continuing until the beam time allotment for general users has been met.
Scheduling Beam Time
Beam time schedules are finalized by the beamline scientist in consultation with users. See the ALS Beamlines Directory for beamline scientist contact information.
Access to the Molecular Foundry
It is possible to request access to the Molecular Foundry, a national nanoscience research facility at Berkeley Lab, to assist meeting certain minimal needs of an ALS proposal. Users should review these guidelines before completing their proposal.
