A high-sensitivity angle and energy dispersive multichannel electron momentum spectrometer with simultaneous detection in 2π angle range is presented. A newly designed double half wedge and strip anode position-sensitive detector is employed to collect the ionized and scattered electrons passing through a 90° sector, 2π spherical electrostatic analyzer over azimuthal angle range of about 150° for each. Experimental results on argon are presented to exhibit the performance of the spectrometer.
