The operation of the electrooptical modulator of a magnetograph at low frequencies. I - Control voltage instability
Abstract
The topology of high-voltage pulse generator (HPG) circuits designed to control electrooptical modulators of polarized radiation in solar magnetographs is examined. A modified HPG circuit with multiple control which has been tested at the Sayan Observatory is described. The modification is based on the use of a high-voltage pulsed transistor.
