“…The idea behind the gap is fairly simple and has been applied on several occasions [3,17,18]. Since the refractive index of the fibre's core and the claddings is greater than that of the air, some of the photons reaching the gap border will have an incident angle large enough to get reflected back to the fibre, according to Snell's law.…”

“…One of the most common applications of plastic scintillating fibres in today's high energy physics experiments is in the field of scintillating tracker detectors. Since organic scintillators are among the fastest ones, this kind of detector can be used for precise time-of-flight measurements and is often incorporated as an element of topological trigger devices [1][2][3][4]. Whenever considering precise time measurements, it becomes extremely important to know how sure we are of our measurement, or, in other words, what is its expected error.…”

This paper presents the results of a Monte Carlo study of the time resolution of a scintillating fibre detector and analyses its dependence on the various aspects of detector construction. The estimations of the theoretical time resolutions for detectors with different numbers of fibre layers and different types of acrylic-based fibre coatings are presented. The method is suggested to decrease the rate counting effects encountered in high rate applications. It has been observed that for dual cladding fibres with a fluorinated polymer used for the outer cladding, the most significant factor contributing to the time resolution is the number of fibre layers, with the fibre coating being the marginal one. Another observation shows that the introduction of a gap between the fibre and the photomultiplier glass window allows the reduction of the number of photoelectrons by 25% with only a slight decrease in the time resolution, which may be helpful in decreasing the pulse pile-up effects and the photomultiplier gain, commonly observed under high rate conditions.

“…Several alternative solutions are currently being studied to provide a more accurate time reference corresponding to the arrival of incident ions or ion bunches. Among them, some devices under development based on scintillating fibers provide particles tracking with integration [18] or particle-per-particle [19][20][21] acquisition mode for various fields of application, including proton radiography [22] and ion-range verification during hadrontherapy [23]. Recently, the performance of a time-tracker for a prompt-gamma spectroscopy system allowing for a background TOF rejection with a sub-nanosecond time resolution has been demonstrated [24].…”

A beam tagging hodoscope prototype made of squared 1 mm 2 fibers arranged in two perpendicular planes and coupled to multi-anode photomultipliers has been studied using 65 MeV proton as well as 95 MeV/u 12 C beams at various intensities. This hodoscope successfully provided 2D images of proton beams with a detection efficiency larger than 98% with logical OR condition between the two fiber planes. The detection efficiency with a coincidence between the two planes is close to 75% for beam intensities up to ∼ 1 MHz. Moreover, the timing resolution is around 1.8 ns FWHM. Overall, the performances show that such a technology is viable for beam monitoring during hadrontherapy. K: scintillating fibers, beam monitoring, hadrontherapy 1Corresponding author.
