New concepts for scintillator-based particle tracking detectors

About

Scintillator-based detectors are widely used in particle physics experiments, owing to their tracking and calorimetric capabilities.

Traditionally, high spatial resolution alongside a massive active target requires both segmentation and optical separation, that comes at the cost of increased manufacturing complexity and a massive number of readout channels.

To overcome these challenges, newly developed technologies aim to enhance 3D tracking performance without sacrificing target mass. For organic scintillators, current efforts include the high-precision assembly of tiny scintillating plastic cubes or fibers, as well as 3D-printing optically-isolated voxels within monolithic blocks. Similarly, 3D optical separation or tracking in opaque liquid scintillators present promising options.

Finally, sub-millimetre tracking resolution using arrays of plenoptic cameras imaging a volume of scintillato, without the need of segmentation or optical fibers, can be made possible by ongoing developments in photosensor technologies.

After a brief review of scintillator detectors deployed in current experiments, I will discuss ongoing R&D geared toward future detectors and experiments.
