The Forward Spectrometer for Exclusive Study of the Roper Resonance at Saturne II Accelerator (LNS, CE Saclay)
This is a brief description of the forward spectrometer which was used as a part of SPES4π installation for an exclusive investigation of the p(α,α 1)X and p(→ d,d 1)X reactions at the SATURNE-II accelerator (CE Saclay). The spectrometer was designed to register the products of the recoil particle decay and to select the specific channels of the reaction. It consists of a set of multiwire drift chambers and scintillation counter hodoscope and was especially adapted for the operation close to a high intensity direct beam of the accelerated particles. The main parameters of the spectrometer and the results of its test are presented.
