Measuring small field profiles and output factors with a stemless plastic scintillator array

Abstract: To fabricate a 1D stemless plastic scintillation detector (SPSD) array using organic photodiodes and to use the detector to measure small field profiles and output factors. Methods: An organic photodiode array was fabricated by spin coating a mixture of P3HT and PCBM organic semiconductors onto an ITO-coated glass substrate and depositing aluminum top contacts. Four bulk scintillators of various dimensions were placed on top of the photodiode array. A fifth scintillator was used that had been segmented by lase… Show more

“…Both organic and inorganic compounds have been investigated as luminescent detectors in FOD, with plastic scintillators (PSs) the most studied materials so far 7 . PSs are made of aromatic hydrocarbon molecules, thus absorbing ionizing radiation similarly to water and soft tissue at megavoltage photon energies 8 . For this reason, PSs are considered tissue equivalent ionizing radiation detectors, which is one of their most relevant characteristics.…”

“…7 PSs are made of aromatic hydrocarbon molecules, thus absorbing ionizing radiation similarly to water and soft tissue at megavoltage photon energies. 8 For this reason, PSs are considered tissue equivalent ionizing radiation detectors, which is one of their most relevant characteristics. One drawback affecting PSs is their relatively low scintillation light yield, which poses a challenge to optimize optical coupling and light collection in PS-based FOD instrumentation.…”
