The Great Bipolar High Voltage Power Supply Installation of 2017

What is a bipolar power supply and why do we need it? In the Ra EDM experiment, a high electric field flips sign on a roughly 1-minute cycle. The direction of the field is changed by reversing the sign, or polarity, of the voltage being applied across the “hot” cathode (field is defined by positive-to-negative charge direction). ...
