Timing of applying the control voltage to the solid-state switches and the output of the ratemeter. When +10.2 V (−10.2 V) is applied to the switches, the coincidence of the two photons emitted from the same (different) bunch is taken, and the coincidence rate increases (decreases). Consequently, the phase difference between the control voltage generated by the function generator and the output of the SCA is zero. |
