Natural diamond is being an attractivematerial since it was discovered due to its many numerous mechanical characteristics.The small size of carbon atom and diamond lattice structure give it uniquephysical features. However, poor electrical properties and rarity of diamondhave reduced research interest. Researchers reconsidered the usage of diamond inradiation detection field after first synthetic diamond was fabricated, nearlythree decades ago, with remarkable properties using Chemical vapor deposition (CVD) growthtechnique 1.
CVD has been utilizedto grow high purity polycrystalline CVD (pcCVD) diamond. However, pcCVD diamondhas a significant issue with charge collection due to grain boundaries 2. Because of that, Element Six fabricated a single-crystalCVD (scCVD) diamond with semiconducting properties 3. scCVD diamond outstanding properties including highresistivity, due to the high-band gap, which lead to diamond room temperatureoperation with negligible leakage current 4. In addition, high displacement energy (43 eV)required to displaced carbon atom in diamond sensors resultsin high radiation hardness 5. Recent studies demonstrated diamond reliabilitywith high luminosity experiments 4, 6, 7.
Highsaturation velocity beside the large mobility of carriers lead to a superior time resolution 8, 9. Radiation hardness and fast timing capability aretwo essential properties that make CVD diamond sensors a candidate alternativefor current silicon detectors inhigh energy physics tracking experiments 10-12. Further, RD42 collaboration was established to develop diamond sensor forhigh luminosity experiments at Large Hardon Collider (LHC) 13. Recently, the collaboration succeeded tofabricate 3D diamond detector with low voltage bias and high charge collection efficiencyfor future heavy-ion experiments 14. In this paper, energy deposited (?E) measurements in twoparallel scCVD diamonds are presented for proton and ironenergetic beams and its produced secondary particles from bombardment throughthick polyethylene targets.
Geant4 simulation is built to compare measured withsimulated spectra and, also, to investigate and analyze peak formation on themeasured spectra 15. In addition, simulation studied thefeasibility of the construction of a particle identification system using energydeposited in diamonds sensors with the Time-of-Flight (ToF) technique 16.
