What if I submitted a proposal for a previous cycle?

Proposals submitted for previous run cycles that are still active can request beam time by submitting a follow-on experiment time request (ETR) for 2025-2. Log into UPS using your ORCiD credentials and follow these step-by-step instructions.

All proposals for the APS are submitted via the Universal Proposal System (UPS). For everything you need to know about the UPS, from logging in to requesting beam time, visit Using the Universal Proposal System.

In order to submit and/or be listed on an APS proposal, users must:

1. Have an APS/Argonne badge number AND an ORCiD with APS authorized as a Trusted Party in your account. If you do not currently have a badge number, please register as a user.
2. Log into the UPS platform and create your user profile.

Please follow these detailed login instructions to access your UPS dashboard. Watch a demo of the UPS system for additional assistance. 

Time Zones and a 24-Hour Clock

The UPS has built-in customizable time zones. Head to your UPS user profile to select your appropriate time zone. All dates and times displayed in the system will update accordingly. If you do not update your time zone, it will default to Pacific time.

The UPS displays all times using a 24-hour clock. For example, a 2:00 p.m. deadline in Chicago (Central time) will display as 14:00.

IMPORTANT TIP!

Please be sure to be as thorough and detailed as possible with your abstract AND when answering all proposal form questions. Beam time for the upgraded APS will be highly competitive. To give your proposal the best chance at allocation, be in-depth with your responses. See our tips for writing a successful APS proposal.
