Add to ORKGA prototype of S-band RF photogun with GaAs photocath-ode has been built and tested at Novosibirsk. The main goal of this prototype is to check a possibility of long time oper-ation for GaAs photocathode in a strong accelerating field of RF cavity. The first experimental results concerning dark current and lifetime of GaAs photocathode in NEA condi-tion under high RF power are presented. The dark current observed is much higher than predicted. Possible mecha-nism of large dark current emission from NEA surface is suggested and discussed.
