Hybrid Detector

Overview

Ionization chambers and DSSSDs have their own strengths and weaknesses. An ionization chamber has relatively poor resolution compared to the DSSSD but compensates for this with the ability to discriminate recoils from isobaric contaminants by their energy loss signal. A DSSSD has superior energy resolution, timing capabilities, and produces a strong E signal but is often unable to separate isobars which are very close together in kinetic energy. The Hybrid detector will consist of an ionization chamber set in front of a DSSSD along the beam axis to act as a superior ΔE-E end detector that can discriminate isobaric contaminants from the beam particles and from the recoils while preserving high resolution and fast timing capabilities.
