Hemispherical electron analyzer

Photoelectrons with specific kinetic energy range are selected by hemispherical electron analyzer and projected to the channel plate at the analyzer exit slit. The channel plate is a 48 channel electron cascade multiplier set along the dispersive plane of analyzer. The energy window and separation between channels is proportional to the pass energy of analyzer and shown on the table at the bottom. Using mutichannel plate one can reconstruct spectrum from selected area of the sample image.
