The gold plated cylinder on the left of the instrument is the 30 kV power supply. The electrostatic analyzer also contains the light traps that serve to block UV and visible radiation. If the ion is energetic enough to trip the SSD threshold, the SSD provides a residual energy measurement. The collimator vanes are shown in the cut-away view at the bottom right. Inside each unit are schematics of each subsystem and the institutions that were responsible for the components.
Arrows show flow of ions, signals, and power among the subsystems.
