==Construction==

A spiral VIG consists of four alternating conductor-insulator-conductor-insulator sheets, wound into a cylinder, forming a [[capacitor]] also acting as a single-ended [[transmission line]], connected to a [[spark gap]] switch. The capacitor is charged from a power source, e.g. the EDFEG, then the spark gap fires after its [[breakdown voltage]] is reached. The [[electromagnetic wave]] created by the [[electric spark]] discharge travels along the transmission line, converting [[electrostatic field]] to [[electromagnetic field]], then after reflecting from the open end converts back to electrostatic field. A pulse of output amplitude 2nU (where n is the number of turns of the capacitor and U is the initial voltage it was charged to) and a rise time equal to twice the [[electrical length (transmission medium)|electrical length]] of the transmission line.[<ref>http://scholarsmine.mst.edu/post_prints/pdf/physics_09007dcc80588630.pdf][</ref><ref>http://www.boliven.com/patent/US7151330/drawings][</ref><ref>http://shadaly.com/vector_inversion_generator_4507567.html]</ref> The device acts as a distributed [[pulse forming network]].

[[Ferrite (magnet)|Ferrite]]s can be attached to the VIG construction to modify its characteristics.[<ref>http://www.findthatpatent.com/Apparatus_and_method_for_generating_high_voltages_using_a_voltage,7151330.html]</ref>

==Applications==

Line 11:

The use of VIGs includes [[directed-energy weapon]]s, [[x-ray]] pulse power supplies, [[plasma (physics)|plasma]] generators, etc.

VIGs can be constructed by high-voltage hobbyists.[<ref>http://4hv.org/e107_plugins/forum/forum_viewtopic.php?43795.last][</ref><ref>http://www.sciencemadness.org/talk/viewthread.php?action=printable&fid=6&tid=6032]</ref>
