NX-28 collimator control and driver instrument

An electronic instrument is presented for controlling and driving collimators planted on the isotope producer beam of the cyclotron. 2 collimators can be set into different positions independently by means of this instrument which can be controlled from 3 places. The collimator positions are indicated by lamps in each. The instrument is usable not only for controlling the collimators of an isotope-producer beam but for other similar, up to four-position collimator settings, too. The adjustment accuracy of the collimator axle is better than +-0.75 degrees. (author)
