Figure 6
(a) Time diagram for the frame-skipping operation at 30 Hz with SDD = 19 m. Frames 1 from even-numbered pulses (at 0, 33.33 ms etc.) are allowed to pass through the choppers. At the same time, frames 3 from odd-numbered pulses (at −16.67, 16.67 ms etc.) are allowed to pass through as well. On the detector, these two frames do not overlap and can be treated separately. (b), (c) Neutron leakages through the choppers from even- and odd-numbered pulses, respectively. |
