Quasi-Elastic Light Scattering Diagnostics for a High Voltage Spark Discharge
… in a unipolar, positionally stable, high voltage spark discharge. The material transport by particulate intermediates was studied. Instrumentation was constructed to allow spatially-, temporally-, and angularly-resolved scattering measurements on the positionally stable spark discharge. Active …

Hydrodynamic, acoustic, and electrical characteristics of underwater spark discharges initiated by different mechanisms
Underwater spark discharge is one of the most common methods to generate intense acoustic impulses in water for different purposes in practical applications. As compared with chemical explosion, the underwater spark discharges provide a number of advantages: they do not generate toxic compounds or …

Gas electron multipliers and a scanner for automated quality control
… holes of a 10 x 10 cm GEM induces a spark discharge, the entire GEM is useless. Computer simulations have also shown that amplification behavior is strongly dependent on hole diameter and shape. To improve foil quality control, an automated scanner has been constructed to optically …

AN EXPERIMENTAL AND NUMERICAL STUDY ON CAVITATION BUBBLE DYNAMICS AND ITS BIOMEDICAL APPLICATIONS
… experimentally investigated. A novel low-voltage spark discharge method is also developed, which is capable of generating consistent-sized cavitation bubbles. Numerical simulations using a boundary-element model based on the potential flow theory are conducted to complement these experiments, and …
