Abstract :
In this paper we present the system comprising of both experimental and surface preparation chamber allowing measurement of emitted photoelectrons with an electron time of flight in ultra high vacuum conditions. A novel approach to vibration isolation decouples the vacuum chambers and pumps from the optical and sample manipulation to unprecedented levels. Key to this feature was modification of a transfer arm allowing samples to be translated in 5 axes before the laser. A further modification of the arm allows 6 samples to be investigated in turn under the same experimental conditions.
