Combined Electron and Ion Spectrometer:

MEDUSA (Miniaturized Electrostatic DUal-tophat Spherical Analyzer)

MEDUSA is a combined electron and ion spectrometer. The instrument sensor is provided by the Southwest Research Institute, San Antonio, Texas. Electrons and ions with energies up to 17 keV/q will be measured simultanoesly, with a resolution of 4 energy sweeps per second for electrons, and 2 sweeps per second for ions. Particles are measured in 16 sectors in the plane of acceptance, which is aligned with the Earth's magntic field.
The mass of MEDUSA is 600 g and the power consumption is 900 mW.

Neutral Particle Detector:

DINA (Detector of Ions and Neutral Atoms)

The objective of DINA is to extend the measurements of the precipitating ions to the higher energy range 20 - 1200 keV complementing the MEDUSA experiment. The instrument is a solid-state detector, and is completely designed and built by people at IRF. DINA consists of two sensors with the aperture 5 * 30 degree each. The sensor DINA-0 is looking at 180 degree pitch-angle and DINA-90 at 90 degree pitch-angle.
The mass of DINA is 340 g and the power consumption is 500 mW.

The magnetometer will allow us to determine the satellite attitude by monitoring the field in the Y and Z direction of the spacecraft.
