A compact magnetic analyzer for magnetic proton recoil spectrometer has been developed at CAEP.Nd-Fe-B permanent dipole is used as the analyzing magnet
with a focal plane detector of CR39.Performance of the analyzer was studied with the actual magnetic field distribution and charged particle transport code.Experiments were performed with a 239Pu α source.Capability of the spectrometer was studied with Monte Carlo simulations and the transport code.The results show that proton and alpha particles of 3.5-8.5 MeV can be analyzed by the magnetic analyzer with an excellent capability of momentum dispersion and radial focuses
which meet the requirements of compact MPR spectrometer.The MPR spectrometer has an energy resolution of about 4% and detection efficiency of about 10-8 for DT fusion neutrons.
