Proposal Submission

Now accepting General User Proposals for Remote Experiments

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.

Now accepting General User Proposals for Remote Experiments*

* Due to the COVID-19 pandemic, external users are not allowed onsite to conduct experiments at the APS. Therefore, all experiments at the DCS are being performed with users participating remotely.

New General Users at DCS

If you are interested in conducting General User Program experiments at DCS, please take the following steps:

  1. Review the DCS General User Guidelines (additional guidance regarding the procedures for conducting experiments remotely will be provided if you are allocated experimental time)
  2. Review and confirm that you can assemble complete targets according to the target preparation procedures for plate impact or laser shock experiments. All users are required to provide fully assembled targets at least 1 week in advance of scheduled user experiments.
