Novel multi-layer plastic-scintillator-based solid active proton target for inverse-kinematics experiments

Multi-Variate Gaussian-Based Inverse Kinematics

Inverse kinematics (IK) equations are usually solved through approximated linearizations or heuristics. These methods lead to character animations that are unnatural looking or unstable because they do not consider both the motion coherence and limits of human joints. In this paper, we present a method based on the formulation of multi-variate Gaussian distribution models (MGDMs), which precise...

Development of SiPM-Based Scintillator Tile Detectors for a Multi-Layer Fast Neutron Tracker

We present the development and characterization of thin tile scintillator detectors with silicon photomultiplier (SiPM) readout for use in a multi-layer fast-neutron tracker. The tracker is based on interleaved Timepix and plastic scintillator layers [1]. Fast-neutrons recoil protons in the plastic scintillators, which may then travel to and stop in the neighboring Timepix. Using the measured r...

Quality assurance in proton beam therapy using a plastic scintillator and a commercially available digital camera

PURPOSE In this article, we evaluate a plastic scintillation detector system for quality assurance in proton therapy using a BC-408 plastic scintillator, a commercial camera, and a computer. METHODS The basic characteristics of the system were assessed in a series of proton irradiations. The reproducibility and response to changes of dose, dose-rate, and proton energy were determined. Photogr...
