摘要： The significant modifications to our recently constructed electron momentum spectrometer have been implemented. Compared with our previous report, the energy and the angle resolutions are significantly improved and reach ΔE=0.45eV, Δθ=±0.53o and Δπ=±0.84o, respectively. Moreover, the details of data reduction and the relation between azimuthal angle range and the sensitivity are discussed.

Abstract: The significant modifications to our recently constructed electron momentum spectrometer have been implemented. Compared with our previous report, the energy and the angle resolutions are significantly improved and reach ΔE=0.45eV, Δ$\theta$=±0.53o and Δ$\phi$=±0.84o, respectively. Moreover, the details of data reduction and the relation between azimuthal angle range and the sensitivity are discussed.
