| Popis: | An instrument is described that performs the following timing functions: (a) selection of time intervals which lie within a preselected range; (b) upon occurrence of a selected time interval, generation of three real time triggers, two of which are delayed by separately adjustable multiples of the time interval and one of which coincides with the end of the interval. Function (b) is especially valuable in time coincidence work with poorly analyzed beams or with particles of indeterminate and widely varying velocity; an example of this type of application is discussed. Circuit values are given for a unit with time interval limits continuously variable within 1–10, 10–100, and 100–1000 μsec ranges and with time interval multiplying factors continuously variable from 0.1 to 1 or from 1 to 10; design equations are presented to facilitate modification of these values, as may be required for other applications. |
