Proposal Deadline
The DCS utilizes the APS Beam Time Access System to receive all proposals for experimental time at the DCS (CAT and General User). Because of the unique challenges in creating a user schedule for the DCS, the schedule is created one Run ahead of the normal APS schedule. For example, the submission deadline for Run 1 of any calendar year for other APS sectors shall correspond to the deadline for Run 2 (of that same calendar year) submissions for DCS Users.
Explanation of Shift Allocation at DCS for Experimental Time
- When submitting your proposal in the Beam Time System for DCS experimental time, you will be asked to specify the number of shifts required to complete your experiments.
- One shift = 8 hours.
- The DCS allocates user time on a per day basis (not by individual shifts), 3 shifts will be charged toward your proposal for one day of experiments. Two days of experiments = 6 shifts, and so on.
