Participant Registration

Please read carefully



You have been assigned to an ATPESC contact person to assist you with any of your ATPESC-related questions or concerns, and to make changes to your travel arrangements. The first letter of your last name determines your ATPESC contact person:

Your designated ATPESC contact person will follow up after you register with the details regarding your travel itinerary.



Lodging is at the single-occupancy ATPESC group rate at the event venue. Your ATPESC contact person will handle your lodging arrangements via our online registration system. Lodging dates covered are: Sunday, July 28 through Friday, August 9, 2019. However, International travelers and West Coast (California, Seattle, etc.) travelers arriving on Saturday, July 27 will be also eligible for lodging that additional day. Your room reservation will be based on the travel itinerary you provide when you register. Local participants are also eligible for lodging and encouraged to stay at the event venue the whole duration of the program.

Please make reference when you register if you are attending with non-event travel companions, or if you require additional amenities or services (you will be billed separately by the hotel). Upon hotel check-in, the hotel reception desk will request a personal credit card for extra charges incurred to your room during your stay (i.e., companion, any upgrades, or amenities).


Daily Meals (breakfast, lunch, dinner and breaks) at the venue are provided for ATPESC 2019 Participants with the following exceptions:

  • Sunday, July 28 – no breakfast or lunch provided
  • Saturday, August 3 – no lunch or dinner provided
  • Sunday, August 4 – no lunch provided

Notes: Meals for non-event travel companions are not included. If you have dietary requirements, please specify these as you register.


Air Travelers

  • U.S. domestic flights
    Your ATPESC contact person will need to arrange your flight through the Argonne Travel Department. Travel dates are:

    • Arrival: Sunday, July 28, 2019. However, West Coast (California, Seattle, etc.) participants will have the option to arrive on Saturday, July 27, 2019.
    • Departure: Saturday, August 10, 2019

    Your flights will be scheduled to arrive between 9:00 a.m. – 12:00 p.m. on July 28, and to depart on August 10. When registering, please give your flight preferences. You will have the opportunity to approve your itinerary prior to booking.

  • International flights
    International flights are not covered. Participants flying from outside the U.S. will need to book their own flights in such a way that they ensure attendance during the full program (Sunday, July 28 through Saturday, August 10, 2019).
  • Ground transportation to/from the Chicago-area airports (ORD or MDW)
    1. Ground transportation for U.S. domestic and International flight travelers is covered only through the Limousine Service or ATPESC bus provided.
    2. Once your travel and lodging arrangements are made, your ATPESC contact person will provide additional information about that service. Participants will share a bus to the airport for the departure. If you are traveling with non-event travel companions, you will need to provide a credit card for those charges separately.
    3. Rental cars are not covered.

Local Travelers

Local participants who are driving will be reimbursed for travel expenses that represent an incremental cost above normal commuting costs.  For example, Argonne will compare the mileage for your normal daily commute (home to/from work) with the mileage for your ATPESC attendance (home to/from Q Center) and will reimburse the mileage difference if the local travel incurred into additional mileage. Please provide your ATPESC contact person with a Google map confirming mileage (round-trip) from your home to the event location.

This very popular tour includes the Argonne Leadership Computing Facility (Data Center and Visualization Laboratory – ALCF), the Advanced Photon Source (APS), the Nuclear Energy Exhibition Hall and if available, the Argonne Tandem Linac Accelerator System (ATLAS).
