Reversing rectangular pulse generator applicable to transient electric birefringence.
An electronic reversing rectangular pulse generator, which can be used for experiments on electric birefringence in macromolecular solutions, was constructed. The performance was very satisfactory when four thyratron tubes of 2D21 or 1G50 type were used. The switching time for pulse reversing was less than 50 ns even without very careful wiring of the circuit. Transient electric birefringence for the common strain and HR strain of tobacco mosaic virus was demonstrated as a preliminary experiment.
