The NEW APS has NEW Procedures for Users

Table of Contents

ANL domain accounts are now required to access user platforms (My APS Portal, ESAFS, Safety Training, EEFs, etc.).
To use your domain account you must have current, active user access (contact apsuser@anl.gov).
When logging in, your username is the letter "b" followed by your user badge number (e,g., b12345).
For self-service to reset your password use this link.
If you need assistance with your domain account or password, contact the help desk at 630-252-9999 option 4.
NOTE: You will need your badge number and picture ID for the Help Desk to reset your password, and a zoom call will be required.

Dosimetry information can be found here.
Dosimeters must be worn at all times while on the experiment hall floor (they are not required in the LOMs).
They should never be taken out the APS building. Leave all dosimetry badges on a dosimeter rack located by the exit doors of all LOMs.
Request your dosimetry badge a minimum of 3 business days prior to arriving at Argonne. You can do so in My APS Portal.
Pick-up your dosimetry badge at the LOM you requested, or the coat room at building 401 on the first floor outside of the User Program Office if no pick-up location was selected.

APS Building 401 doors are locked weekdays from 7:00 p.m. through 7:00 a.m. and 24 hours on weekends.
An activated prox card access is required for access.

Onsite users on fully approved ESAFs arriving during normal Argonne Welcome Center hours (Monday through Friday, 6:30 a.m. – 4:00 p.m.):
User photo badges will be issued for the duration of the experiment, including set-up and take-down. You do not have to request a gate pass.
Onsite users on fully approved ESAFs arriving AFTER Argonne Welcome Center hours or on a weekend:
You must request a gate pass for your access via your APS User Portal, and your access credentials are held for pick up at the Main Gate Guard Post.
Users should bring appropriate identification when arriving at Argonne. REAL ID is now required for Argonne site access.
User badges should be worn at all times while on-site. User badges should be returned to the guard post upon final departure from the laboratory. Do not allow your badge to be photographed.
All users must check in at the User Program Office, Building 401, to have their prox cards activated for access to the APS building and experiment hall.
Additional user check list information can be found here.

For transportation on campus during your visit, you can utilize LabCab, Argonne's newly-introduced on-site rideshare service. The service is available 7:00 a.m. to 5:30 p.m., Monday through Friday. Rides can be obtained on demand or reserved in advance. Download the TripShot app to utilize this service.

The UPS is the new proposal submission platform at the APS.
Please follow these detailed instructions to log in and access your UPS dashboard.

Your ESAF form must be submitted two weeks in advance of an experiment to allow time for reviews. Submit HIGH RISK ESAFs six to eight weeks in advance. For MX beamlines, submit seven days in advance.
Users must have an APS badge number in order to be added to an ESAF.
For ESAF-related inquiries contact esaf_system@aps.anl.gov.

A Gate Pass is required for users arriving one evenings, weekends, and holidays. Gate pass requests must be submitted in My APS Portal by the deadlines listed below (all times listed are Central). If you will be arriving on a holiday or laboratory shutdown period, please contact the APS User Office.
- Evening Arrival (after 4:00 p.m., Monday-Thursday) deadline for request-1:00 p.m., date of arrival.
- Weekend Arrival (Friday after 4:00 p.m., Saturday, and Sunday) deadline for request-1:00 p.m., Thursday prior to arrival.
Secure your Gate Pass as early as possible to ensure site access and prevent delays with your experiment. Site access cannot be guaranteed if a request is submitted after the deadlines above, and entry may be denied.

For individuals arriving using a taxi, limo, or rideshare service will need to obtain a gate pass for their driver to enter the Argonne campus. The pass can be issued on arrival at the Argonne Welcome Center (AWC) during business hours or from the security gate officer during off-hours.
Visitors checking into the Argonne Guest House can request a shuttle from the AWC to the Guest House between the hours of 8:00 a.m. and 5:00 p.m., Monday through Friday.
For Argonne visitor questions, call 630-252-5755.
Food deliveries from DoorDash, Grubhub, Uber Eats, and local restaurants can now be picked up in the vestibule of Building 224, the Argonne Welcome Center. Users are able to meet the delivery driver at the Welcome Center or the vestibule area is open 24/7 and has a small pick-up shelf for drivers to drop off orders. Delivery drivers will not be allowed access to the Argonne site.

To meet U.S. Department of Energy Office of Science requirements, the APS began collecting limited demographic information via the user registration form in October 2024. Participation in providing this information is voluntary, with an option to respond with "do not wish to provide" for each question.
Please note that your individual demographic details will remain confidential, used only in aggregate, anonymized formats to fulfill reporting and facility review requirements. This initiative helps us understand the diversity of our user community and supports equitable access to our resources. For any questions, please contact: apsuser@anl.gov.
