摘要：
A simple high precision digital delay for nuclear physics experiments was developed using fast ECL electronics. The circuit uses an oscillator synchronized with the signal to be delayed and a presettable counter It is capable of delaying a negative NlM signal by 2 is with a precision better than 50 ps. The circuit was developed for use in slow-fast coincidence units for Perturbed Angular Correlation spectrometers but it is not limited to this application. (C) 2014 Elsevier B.V. All rights reserved.
