Travel Instructions

The DND-CAT Synchrotron Research Center is located at the Advanced Photon Source in Building 432 of Argonne National Laboratory. Please call us at (630)252-0222 before you plan to travel so that we can arrange for a pass to the Laboratory and the APS.

The Laboratory is easily accessible from either Midway or O'Hare Airports.

From O'Hare Airport

Take the Tri-State Tollway (I-294) south to the intersection of I-294 and the Stevenson Expressway (I-55). I-294 is a toll road, so you will need $0.95 in change (there are two tolls at $0.40 and one at $0.15) for the automatic lanes. Alternatively, you can use the manual lanes with a human tolltaker. Take I-55 south to the exit for South Cass Avenue. Exit at South Cass Ave, drive over the overpass and you will see the sign for Argonne National Laboratory. Follow the signs and turn into the Laboratory entrance on Northgate Road. You will need to stop at the Visitor Center to obtain a pass and a map to find the APS within Argonne.

From Midway Airport

Take Cicero Avenue north to I-55. Take I-55 South to South Cass Avenue and then follow the instructions in the above paragraph.

Limousine Services

Several companies serve Argonne. When you make your reservation the company will inform you of the phone number to call when you arrive at either O'Hare or Midway to summon the limousine. For a complete list of limo services see the transportation section of the APS home page or contact the DND-CAT office or the APS Users Office.

If you have GERT (General Employee Radiation Training) from another facility within the last two years, bring proof (GERT Card) and you will not have to test at the APS.
Once you have completed these steps you will be issued a Photo ID Card that will allow access to the Argonne Campus and is a cardkey for the doors at the APS.
