Abstract

Experimental and computational results of a ΔE/ΔE diamond detection system are presented. The ΔE/ΔE detection system was evaluated using energetic proton and iron beams striking thick polyethylene targets at the NASA Space Radiation Laboratory (NSRL) at Brookhaven National Laboratory (BNL). The measured data for diamond sensor A show good agreement with the Geant4 simulation. In addition, simulations have demonstrated the ability to identify hydrogen isotopes using a diamond detection system.

Highlights

Diamond is an attractive material because of its many electrical, chemical, and mechanical characteristics [1,2,3,4]
Its consistent application in radiation sensing occurred after synthetic chemical vapor deposition (CVD) growth of diamond was demonstrated to produce consistent and suitable properties [5, 6]
Diamond detectors have been explored for use in extreme environments [7,8,9,10,11], microdosimetry [12, 13], and thermal [10, 14, 15] and fast neutron sensing [10, 16,17,18,19,20], including deuteriumdeuterium (DD) and deuterium-tritium (DT) fusion plasma diagnostics [21, 22]

Summary

Introduction

Diamond is an attractive material because of its many electrical, chemical, and mechanical characteristics [1,2,3,4]. Its consistent application in radiation sensing occurred after synthetic chemical vapor deposition (CVD) growth of diamond was demonstrated to produce consistent and suitable properties [5, 6]. One extreme environment under consideration for diamond detectors is high-rate particle tracking sensors at the LHC [7, 23,24,25,26]. Ese essential attributes make diamond sensors a potential candidate for current silicon detector replacement technology in high-energy physics tracking experiments [30,31,32]. Geant simulations are used to benchmark and understand experimental observations, with a focus on particle identification using time of flight (ToF) [25, 33,34,35,36]
