CARS will gladly arrange tours for high school and college students and for the general public. In a typical year, more than 100 visitors tour CARS.

Tours usually include a short presentation on how the Advanced Photon Source works and the kind of research we do at CARS, followed by visits to one or more of our sectors. If no experiment is in progress, visitors can enter an experimental station. Tours can also include a stop at the observation decks of the APS, which give a birds-eye view of the synchrotron ring.

Advance notice is required because of restrictions on site access. (Tuesday is a good day to visit, because the machine is shut down and lots of impressive equipment can be opened to view!) We can accommodate groups of 25 or fewer people.
