All experiments at the APS require an approved Experiment Safety Assessment Form (ESAF). Users allowed onsite are those who are identified as Onsite Users on a fully approved ESAF.
ESAFs are submitted through My APS Portal.
- Must be submitted 14 days in advance of the experiment beamtime to allow for Site Access and Dosimeter Requests.
- As early as possible if any nonstandard activities are involved.
Note for users collecting data on or shipping soil samples to the APS:
If you are bringing or shipping soil samples to the APS, the samples must be verified as non-regulated and non-hazardous before arrival. Please include a description of the soil sample and its origin on the ESAF.
If you are unsure whether the soil may be regulated, contact Liz Schmidt and provide the sample origin, including city, state, and/or country. Additional instructions will be provided.
More information:
All users accessing the APS experimental hall must wear a dosimeter.
Submit dosimeter requests at least 72 hours (3 business days) in advance.
Do not request a dosimeter unless you are current on General Employee Radiological Training (ESH738).
Request a Dosimeter through My APS Portal.
More information:
APS user courses can be completed remotely through My APS Portal.
Required training must be complete before APS will approve your Experimental Safety Assessment Form (ESAF).
There may be additional training depending on the experiment.
More information:
Onsite users must complete a two‑part Sector orientation before beginning any lab work.
Part 1: Read the linked document and acknowledge completion by submitting the Microsoft Form at the end.
Part 2: An eBERlight staff member will review the lab safety orientation checklist with you and post the ESAF with the floor coordinator.
