a ToF spectrum obtained with the 3He-tube below (black line) and above (red line) threshold. b ToF spectrum obtained with the the Multi-Blade detector below (green line) and above (blue line) threshold. Both are recorded in ToF range between 100 to 105 ms, i.e., when the neutron beam hits against the chopper
