Casual visitors who wish to attend educational events or contact employees at IUCF should enter the building at the main entrance on Milo B. Sampson Lane and discuss their needs with the receptionist in the lobby. He or she will be happy to accommodate visitors in any possible way.
Recent re-evaluation of security requirements within the United States and within Indiana University have necessitated that visitors to IUCF must comply with a few regulations before entering the research sections of the facility. Accelerators produce radiation and materials that have been exposed to this radiation may become activated. Compliance with our safety and security policies will make your visit both informative and safe.
