2014

  • 08/20/2014 Big news for graduate student Paul Rumbach. First, he was just married (08/16/2014) on an Indian Reservation in Arizona, riding a horse to the big day! Second, Paul is the lead author on a paper titled "Experimental study of electron impact ionization in field emission-driven microdischarges," that was recently accepted by Plasma Sources Sciences and Technology and features gradaute student Yingjie 'Jay' Li, and undergradautes Santiago Martinez and Thibault Twahirwa as co-authors. In the paper, we present experimental evidence for how field emission-driven microdischarges behave at different pressures, showing that the current increases in a log-linear fashion with pressure due to the formation of electron avalanches. Congratulations all!
