Wire Exploder

Production of nanopowder with wire explosion will utilize the custom-built electrical system and explosion chamber. This system principally consists of a 40 kV, 7.5 mA DC power supply (Glassman High Voltage), two 20 mF capacitors (Condenser Products), a trigatron spark discharge switch (R. E. Beverly III & Associates), instrumentation to monitor current and voltage during charging and discharge, and a number of electrical devices that ensure safe operation of the exploder. The lab contains a walk-in fume hood to contain the explosion chamber.  Located in the Wiley lab space, French Family Science Center at Duke.
