AMS at the National Institute of Nuclear Physics and Engineering in Bucharest

A new beam line and injector deck for AMS measurements have been built at t he 8 MV tandem accelerator of the National Institute of Nuclear Physics and Engineering, Bucharest, Romania. The main components on the low-energy sid e are a high-current cesium sputter source, a 90 degrees injection magnet a nd a pre-acceleration stage. At the high-energy side the beam line is achro matic, consisting of two 90 degrees analysing magnets with mass energy prod uct 120 MeV amu and a gas-filled ionization chamber. The system will be com plete with a Wien filter and a multi-anode gas detector with time-of-flight discrimination. Presently, the AMS facility is undergoing tests and routin e measurements are expected to start soon. (C) 2000 Elsevier Science B.V. A ll rights reserved.
