We have developed a new electrostatic analyzer which enables medium energy plasma particle measurements with full solid angle coverage. The design of the test model realizes the uppermost measurement energy of with applied high voltages of . 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.
