Magnetically Delayed Pseudospark Switch
We have investigated the properties of a magnetically delayed pseudospark switch (PSS). One of the challenges of all low pressure gas discharge switches is the reduction of the lifetime due to commutation losses resulting in anode heating. This effect can be minimized by carefully dimensioning the saturating inductors. For many decades, this method has been successfully used for thyratrons. In ...
متن کاملPseudospark Switches (pss) for Pulsed Power Applications
Basing on the pseudospark discharge, a low pressure gas discharge in a special geometry, fast closing switches for different pulsed power applications have been designed. Medium power PSS (< 30 kA peak current) were used in laser circuits whereas high current PSS are tested successfully in high current pulsed power applications (< 200 kA). For currents of a few kA the discharge is supported by ...
متن کاملPseudospark Switch Development for the LHC Extraction Kicker Pulse Generator
CERN, the European Laboratory for Particle Physics, has started construction of the Large Hadron Collider (LHC), a superconducting accelerator that will collide protons at a center of mass energy of 14 TeV from the year 2005 onwards. The kicker magnet pulse generators of the LHC beam extraction system require fast high power switches. One possible type is the pseudospark switch (PSS) which has ...
متن کاملMonte Carlo calculated correction factors for diodes and ion chambers in small photon fields.
The application of small photon fields in modern radiotherapy requires the determination of total scatter factors Scp or field factors Ω(f(clin), f(msr))(Q(clin), Q(msr)) with high precision. Both quantities require the knowledge of the field-size-dependent and detector-dependent correction factor k(f(clin), f(msr))(Q(clin), Q(msr)). The aim of this study is the determination of the correction ...
متن کاملWhy is Plasma Engineering in Fast Recovery Diodes by Ion Irradiation superior to Emitter Efficiency Reduction
This paper presents the comparison of two 4.5kV diodes with expanded Safe Operating Area (SOA) in terms of an expansion to higher line voltages. In order to improve the reverse recovery characteristic the excess carrier concentration close to the anode during the on-state has to be reduced. To control the injection efficiency of the anode two state of the art technologies, the reduction of the ...
