spark-gap generator

spark-gap generator

[′spärk ¦gap ‚jen·ə‚rād·ər]
(electricity)
A high-frequency generator in which a capacitor is repeatedly charged to a high voltage and allowed to discharge through a spark gap into an oscillatory circuit, generating successive trains of damped high-frequency oscillations.

Dornier is the most familiar name among electrohydraulic spark-gap generators.[28,29] The Dornier HM1 (Human Model 1) lithotripter was the first spark-gap generator developed.
In 1986, the FDA approved the Dornier HM3 system, which uses an underwater spark-gap generator to produce high intensity shock waves.[13,20,23,29] An electrical current passed between the electrodes of the spark gap produces an arc that vaporizes water, causing a microexplosion.
The spark-gap generator relies on the discharge of a rapid, high-voltage underwater spark to generate a shock wave that can be focused and transmitted through water.[22] These high-energy waves travel at supersonic speeds through body tissue.
Electrohydraulic, spark-gap generators are associated with a fair degree of pain, and patients generally require anesthesia.
