摘要：

A multichannel electron momentum spectrometer is reported, which combines the features of both a spherical analyzer and a large-area multiparticle imaging detector. The major advantage of the apparatus over the existing setups is its ability to cover almost completely the available azimuthal angle range for the symmetric noncoplanar (e, 2e) reaction. It produces considerable improvement in instrumental sensitivity and approximately three times extension of the coverable momentum range compared with our existing apparatus. A proof-of-performance experiment on Ne is presented and the potential of the developed spectrometer is highlighted for future studies of electron momentum spectroscopy.
