A two-dimensional angular-resolved proton spectrometer

We present a novel design of two-dimensional (2D) angular-resolved spectrometer for full beam characterization of ultrashort intense laser drivenproton sources. A rotated 2D pinhole array was employed, as selective entrance before a pair of parallel permanent magnets, to sample the fullproton beam into discrete beamlets. Theproton beamlets are subsequently dispersed without overlapping onto a planardetector. Representative experimental result ofprotons generated from femtosecond intense laser interaction with thin foil target is presented.
