PRECISION VOLTAGE REFERENCE SUPPLY
Abstract
IN THE OPERATION OF THE MODEL MAGNET FOR CYCLOTRON DESIGN STUDIES THE NEED ARISES FOR AN ULTRA STABLE VOLTAGE REFERENCE SUPPLY. It is necessary that the supply be capable of delivering 1.2 to 1.4 milliamperes to a 1100 ohm load. The voltage reference should be stable to 0.005% over a day's time, operating essentially at room temperature with a maximum variation of 5 C. A device was constructed that used two voltage reference tubes and three zener diodes to obtain this regulation. The voltage supply was placed in an environment in which it was to be used and was monitored for over a month. The standard deviation of the volttage measurements made was 0.0017% with the maximum deviation observed being 0.0023% (Author)
