“…It is an optical fibre composed of a scintillating material. It is more sensitive to fast neutrons and charged particles than to X-rays and gamma-rays because of the circa 1 mm diameter [66], One application is a long counter [67] but more are to be expected in the future. As a contrast it is noteworthy that traditional detectors such as stilbene [68] and the Hornyak button [69] (a mixture of ZnS(Ag) and a hydrogenous material) are still in use.…”

-One-dimensional fiber-bundle arrays may prove useful in a number of radiation sensing applications where radiation detection over large areas is needed. Tests have been performed to evaluate the light generation and transmission characteristics of 15-meter long, 10-fiber bundles of BCF-10, BCF-12, and BCF-20 scintillating fibers (Saint Gobain) exposed to collimated gamma-ray sources. The test set-up used one R9800 (Hamamatsu) photomultiplier tube (PMT) at each end, with a high-speed waveform digitizer to collect data. Time constraints were imposed on the waveform data to perform timeof-flight analysis of the events in the fiber bundles, eliminating spurious noise pulses in the high gain PMTs and also allowing 1-dimensional localization of interactions along the lengths of the fiber bundles. This paper will present the results of these measurements including the attenuation coefficients of the three fiber types and the timing resolution (position uncertainty) possible for each fiber bundle when using the R9800 PMTs.

Purpose Nine scintillator detectors were developed for beam tuning of low-energy single electron accelerator instead of the picoammeter and Faraday cup, both of which will be insensitive to the weak-current beam lower than picoampere. Methods The detectors are based on plastic scintillator and photomultiplier tube (PMT) and the beam is 100 Hz pulsed electrons in the energy range of 0.1 to 50 MeV. The beam flux was tuned from about 10 7 to quasi-single electron for each bunch according to the measurement results of these detectors installed along the beam pipe and after slits. In order to determine the number of electrons in a bunch, the gains of each PMT were finely calibrated, and the energy response of each detector was calibrated with 207 Bi radioactive source. Moreover, the deposited energy in the plastic scintillator, the electron detection efficiency and light collection efficiency, as a function of electron incident energy, were also simulated in detail by Geant4. Results Nine detectors worked well at a gain of 0.6 × 10 6 after installation in the beam pipe, and the number of electrons in a bunch could be measured at each detector position. The single electron peak was seen when the beam reached the final detector. Conclusion The commissioning result shows that the beam was tuned to quasi-single electron level successfully and the
