ABSTRACT:
An electron spectrometer having a wide bandwidth and a high signal-to-noise ratio. Each electron channel sensor is the termination of a 50-ohm transmission line thereby eliminating series inductance and minimizing parallel capacitance, and resulting in increased bandwidths. A metallic grounding screen is provided between the sensor array and the curving chamber of the spectrometer, thereby completely isolating the sensors from the electromagnetic fields in the curving chamber, and resulting in an increased signal-to-noise ratio.
