HiPIMS - Electron energyThe electron energy probability function (EEPF) under therace-track 100 mm below the target for an argon dischargeat 3 (dashed) and 20 (solid) mTorr with a copper target

HiPIMS - Electron energyThe measured EEPF is Maxwellian-like during the pulsehigh electron density leads to a Maxwellian-like low energypart of the EEPFthe depletion in the high energy part is due to the escape ofhigh energy electrons to the chamber walls and inelasticcollisions of high energy electronsThe EEPF is more broad at low pressure and early in thepulse
