Spectrometer for low-energy electrons
Abstract
The paper describes a spectrometer suitable for performing rocket-borne measurements of the flux density, and angular and energy distributions of photoelectrons in the upper atmosphere with energies of 5-70 eV. The field of view of the instrument is 10 x 20 deg, the energy resolution is 5%, the geometric factor is 0.004 sq cm-sr, and the sweep period is 1 sec. A block diagram of the spectrometer electronics is presented, along with circuit diagrams of the recording, sweep, and power-supply units.
