Deuterium-deuterium protons from two counter-streaming ablating plasmas are measured by CR39-based step-range-filter (SRF¹) spectrometer. Several SRF proton spectrometer units are surrounding the target to obtain the proton angular distribution. The proton spectrum was reconstructed using the proton track analysis of different filter thickness and simulations of proton track evolution with etching time. Anisotropic distribution of fusion protons is observed. Further analysis incorporating the results of simultaneous neutron detection will deepen our understandings of counter-streaming plasma dynamics and benefit the diagnostic development for novel laser fusion scheme such as Double-Cone Ignition².
