| dc.title | Hemispherical analyser with 2-D PSD for zero-degree Auger projectile spectroscopy | en |
| heal.abstract | Details of a new high gain zero-degree Auger projectile electron spectrograph using a hemispherical analyser and a 2-dimensional position sensitive detector (PSD) with multichannel plates and a resistive anode encoder are presented. A four-element lens mounted at the entrance of the analyser, provides a virtual slit for the incoming electrons by focusing them while at the same time decelerating them to improve their energy resolution. Electrons enter through an aperture at a position Ro which is displaced (along the energy dispersion axis) with respect to the commonly used central entrance position at 1/2 (R(1) + R(2)) The analyser has an acceptance energy range of 20% and an energy resolution of 0.9%. An ion-optics trajectory simulation indicates improved focusing properties for this off-center position thus avoiding the need for cumbersome fringing field correction schemes. Test measurements of high resolution projectile Anger spectra produced in 21.7 MeV collisions of F(8+) and F(7+) projectiles with H(2) and He are presented. | en |
