The Use of Scintillating Fibers for Charged-Particle Tracking

Abstract

The demand for instrumentation capable of detecting and triggering on ionizing radiation in high-rate particle physics experiments at colliding-beam and fixed-target accelerator facilities and for spacecraft-borne instrumentation in astrophysics has led to the development of new tracking technologies. One of these, scintillating fiber tracking, combines the speed and efficiency of a scintillation detector with the flexibility and hermeticity afforded by fiber technology. A paradigm for a fiber-tracking detector that utilizes organic plastic fibers read out with visible-light photon counters is presented and critiqued. Alternate strategies are considered, and an overview of recent experimental applications is provided.

A multi-purposed detector with silicon photomultiplier readout of scintillating fibers

“…Scintillating fibers coupled to photosensors provide flexible, fast and high granularity detectors which are able to work in high rate environment [1]. The advent of Silicon PhotoMultipliers (SiPMs) has had a strong impact in the development of what we can call a "new age" of fiber based detectors.…”

Scintillators and Wavelength Shifters for the Detection of Ionizing Radiation

“…Over the last decade several techniques have emerged for the readout of particle physics detectors for scintillation tracking and sampling calorimetry. 1,2 For tracking detectors, of which the most ambitious example is the DØ Central Fiber Tracker, 3 each fiber in the tracking detector has its own photosensor. The active detector material is multi-clad polystyrene scintillating fiber of 830µm diameter and in lengths of up to 2.7 m. The scintillator is based on a primary dye pterphenyl and a secondary dye 3-hydroxyflavone.…”
