Description

EPS is a compact TOF telescope with two main components: a TOF section and a Solid State
Detectors (SSD) array. The SSD array comprises six ion-implanted planar silicon detectors,
each with four pixels (two dedicated to ion measurements and two to electron
measurements) for a total of 24 SSD elements. Particles enter the system through a
mechanical collimator that delimits the look direction into the instrument. Particles that
pass through the collimator then transit through a thin, composite Start foil (polyimide +
aluminum, 10 µg/cm2) and onto the TOF region of the instrument.
