A very low pressure activation which allows an improved current emission has been carried out on a GaAs NEA activated photocathode. The experiments show that, under a pressure threshold, several hundreds of uA current are delivered continuously for some days.

Abstract
A very low pressure activation which allows an improved current emission has been carried out on a GaAs NEA activated photocathode. The experiments show that, under a pressure threshold, several hundreds of uA current are delivered continuously for some days.File in questo prodotto:
