keyword=T5 neutrons in new kinematicsAttached is a histogram out of 15 runs (each run 200k) showing TOF spectrum of expected neutrons in neutron array .
The variable plotted is:
chain.Draw("TC_n.ntof",ct&&"TC_n.ntof>100&&TC_n.ntof<700&&TC_n.angle>0.92&&TC_n.nnhits==1");
subject to the following cuts:
TCut ct2by1="CT.ct_2by1*1e9>98.4&&CT.ct_2by1*1e9<100.8&&L.tr.n==1&&R.tr.n==1&&L.s2.nthit==1&&R.s2.nthit==1" ;
