EXPERIMENTAL APPARATUS FOR THE ORNL RIB FACILITY

The individual components of the Oak Ridge Recoil Mass Spectrometer (R MS) have been fabricated and delivered to Oak Ridge, and installation of the spectrometer has been initiated in the new Robinson Hall annex to the Physics Division complex at ORNL. The use of this device, along with its associated detection systems, in the study of evaporation pr oducts from compound nuclear reactions involving medium mass radioacti ve beams, will prove essential for the study of nuclear structure at a nd near the proton drip line. The status of the installation and testi ng of the RMS is reported, as well as the status of the development of the ancillary detection equipment to be used at the focal plane of th e RMS. These include a position-sensitive avalanche counter, ionizatio n chamber, and double sided silicon strip detectors.
