An original design for an electrochemical chamber and the construction of a high-voltage AC generator for electrochemical etching (ECE) of nuclear tracks in CR-39 polycarbonates sheets are presented. The electrochemical chamber was designed and manufactured in an engineering plastic in a vertical machining center. The high-voltage AC generator was built by using different electronic circuits: a signal oscillator, a preamplifier, a power amplifier, two power supplies and a voltage converter transformer. The experimental tests showed that the design of the electrochemical chamber allowed that ECE be developed efficiently, achieving a dielectric breakdown in the polycarbonate, and the generator supplied the electric current in a stable manner and with an excellent performance throughout the ECE. The conditions of chemical etching and electrochemical etching, as well as the electrical treeing generated in the CR-39 are also presented.
