This letter analyzes the transport of an electron beam that is produced during the conductive phase operation in the cathode fall of a pseudospark or back lighted thyratron for applications that require a high brightness electron source. The beam is estimated to traverse the device without thermalization if the plasma density is {le}2.5{times}10{sup 15} cm{sup {minus}3}. High brightness electron sources are necessary for various new plasma based devices, and these results encourage consideration of this electron beam as a new candidate for applications including microwave generation sources, electron sources for accelerators, and plasma based accelerators which require improved cathodes.
