Energy analyzer experiments for the University of Maryland electron ring

The University of Maryland electron ring (UMER) experiment, currently under construction, will be used to investigate the dynamics of space charge dominated low energy (10 keV) electron beams. One point of interest is the energy distribution in the beam. We use an energy analyzer of cylindrical geom...

description The University of Maryland electron ring (UMER) experiment, currently under construction, will be used to investigate the dynamics of space charge dominated low energy (10 keV) electron beams. One point of interest is the energy distribution in the beam. We use an energy analyzer of cylindrical geometry to determine the longitudinal energy of the electron beam. The data can be resolved temporally, which gives an indication of the axial energy distribution in the beamlets. We also have the capability of scanning the beam in the transverse direction so that a lateral distribution of the longitudinal energy may be determined. We present results of energy spread measurements from the injector region of UMER under various conditions. Later efforts will include the effects of bending on the energy spread in the beam.
