摘要: Abstract A TPHC is described which was designed for use with a post-acceleration deflection system operating at 3.525 MHz. The converter started by sharply differentiated pulse from the anode of PM, and stopped derived sine-wave induced in pick-up loop coupled to tuned transformer deflector. deadtime few μsec provided after every conversion. electronic resolution measured be 60 ps, determined aid circuit provides fast low rate, synchronized input sine wave. differential non-linearity as ±2% over 90% range; PHA employed this measurement had manufacturer's specified linearity 2%. integral means new oscillator method developed laboratory. Start stop pulses are independent crystal-controlled sources, curve can without reference calibrated delay lines. time calibration period deflector oscillator. comparison so made that obtained using cables been various methods. major part range least good (0.4%) employed.
