Time-of-flight electron spectrometer for a broad range of kinetic energies.
REVIEW OF SCIENTIFIC INSTRUMENTS(2013)
Abstract
A newly constructed time-of-flight electron spectrometer of the magnetic bottle type is characterized for electron detection in a broad range of kinetic energies. The instrument is designed to measure the energy spectra of electrons generated from liquids excited by strong laser fields and photons in the range of extreme ultra violet and soft X-rays. Argon inner shell electrons were recorded to calibrate the spectrometer and investigate its characteristics, such as energy resolution and collection efficiency. Its energy resolution Delta E/E of 1.6% allows resolving the Ar 2p spin orbit structure at kinetic energies higher than 100 eV. The collection efficiency is determined and compared to that of the spectrometer in its field-free configuration. (C) 2013 American Institute of Physics. [http://dx.doi.org/10.1063/1.4791792]
