Cusp type electrostatic analyzer for measurements of medium energy charged particles
- Institute of Space and Astronautical Science, Kanagawa 229 (Japan)
We have developed a new electrostatic analyzer which enables medium energy ((less-or-similar sign)200 keV/q) plasma particle measurements with full solid angle coverage. The design of the test model realizes the uppermost measurement energy of {approx}200 keV/q with applied high voltages of {+-}5 kV. Laboratory experiments with the test model analyzer show that its performance agrees with numerical simulations. The test model design is well suited for combination with a mass analysis unit, while our new design can also be applied to medium energy electron measurements. Medium energy ion/electron sensors with this new design will surely be appreciated for upcoming space missions that will observe hot/energetic plasma structures in the regions such as the inner magnetosphere or reconnection region.
