2 to 10 Mev Linear Accelerator New Arco Western Service Irradiation Center for

research and product development pilot scale studies limited commercial processing

Now Arco offers you a completely equipped serv­ice center for experimental or pilot plant irradia­tion. Heart of the new Arco facility is a powerful Arco Mark 1-F4 linear accelerator providing a convenient, inexpensive-to-use source of X-ray, electron or neutron radiation. The Irradiation Center is available for single projects or continu­ing irradiation programs. \bur technical person­nel may plan, conduct and evaluate their own ir­radiation program ; our staff assists as desired. Or, samples may be shipped to Arco for irradiation to specification and returned to you for evaluation.
