Gamble II Facility

Metadata Updated: March 8, 2017

FUNCTION: Gamble II produces a high-voltage (2 MV), high-current (1 MA), short (100 ns) pulse of energy of either positive or negative polarity. This terawatt power pulse is used for many Navy, DoD, and Department of Energy research programs including nuclear weapon effects simulation, advanced hydrodynamic radiography, and detection of special nuclear materials. Intense electron beams from Gamble II can interact directly with a target or generate bremsstrahlung to expose test articles to an intense X-ray pulse or to produce a small, intense X-ray source for radiography. Intense ion beams can interact directly with targets or produce characteristic gammas that can be used to probe for special nuclear materials. Another mode of operation uses a plasma opening switch to increase the voltage to 4 MV and reduce the pulse width to 10 ns. The photograph is from an experiment in which a proton beam strikes a support strut of a telescope and induces mechanical vibrations to simulate its response to an intense pulse of ~keV X rays in space.DESCRIPTION: The facility[HTML_REMOVED]s 300-kJ Marx generator is a large capacitor bank capable of producing severalmegavolt voltages. The voltage pulse is then compressed in time duration through a succession of water dielectric pulse-forming lines separated by closing switches to eventually arrive as a high-power pulse across a vacuum diode. This pulse can be applied directly across a load (such as a gas column or wire) or can be used to produce powerful electron or ion beams. These high-power beams are then allowed to interact with X-ray converters or to propagate to a variety of targets. The facility is surrounded by thick concrete shielding to contain X rays produced as a result of the high-power pulses.INSTRUMENTATION: Diagnostics for the generator and the beams are monitored in a shielded room located outside the radiation area. Diagnostics include sophisticated computer-controlled transient recorders or oscilloscopes to record analog signals, numerous optical, X-ray, or neutron diagnostics, and nuclear activation monitors.
