Abstract :
The influence of water vapour on the photoemissivity of GaAs crystals has been measured. Water vapour belongs to the
gases with strong poisoning effects; even small amounts of water below the detection limit of conventional RGA systems
reduce the practical lifetime of a GaAs photocathode. q1999 Elsevier Science B.V. All rights reserved.
