The associated proton monitoring technique study of D-D source neutron yields at the large angle

By selecting a two-direction target chamber and a three-direction target chamber,neutron yields from D-D reaction were monitored at K-400 accelerator with associated proton method.Detectors were put at the direction of 90°?135°and 178.2°refer to D~(+) beam,from which the associated proton spectrum and the Absolute neutron yields were obtained,the accurate experimental condition for neutron yields monitoring was determined,and finally neutron yields monitoring at the large angle(178.2°) was confirmed.Experimental results and it's accuracy were also analyzed and discussed.
