Radiation protection aspects of the decommissioning of the linac-adone storage ring

摘要

An e(sup +)e(sup -) collider, christened DAPHNE (Double Anular (Phi) factory for Nice Experiments), optimized for operation at a total energy of 1020 MeV, is under construction at the Frascati national laboratories (LNF) of the National Institute of Nuclear Physics (INFN). The new machine will be placed into the existing buildings which in the past housed the Linac-Adone complex, which definitively ceased operation April 26. 1993 and was at once decommissioned. The Linac-Adone complex has operated without stopping up to 26th of April 1993 except for the ordinary maintenance periods. It was composed by a Linac, capable of accelerating 100 mA of e(sup -) beam peak current to 400 MeV and 1 mA of e(sup +) beam peak current to 365 MeV, in operation since 1964, and by an e(sup +)e(sup -) storage ring capable of storing 2 x 10(sup 11) particles per beam at 1500 MeV, in operation since 1967.
