摘要：

A novel ion wide angle spectrometer (iWASP) has been developed, which is capable of measuring angularly resolved energy distributions of protons and a second ion species, such as carbon C6+, simultaneously. The energy resolution for protons and carbon ions is better than 10% at similar to 50 MeV/nucleon and thus suitable for the study of novel laser-ion acceleration schemes aiming for ultrahigh particle energies. A wedged magnet design enables an acceptance angle of 30 degrees (similar to 524 mrad) and high angular accuracy in the mu rad range. First, results obtained at the LANL Trident laser facility are presented demonstrating high energy and angular resolution of this novel iWASP. (C) 2011 American Institute of Physics.
