Water-based liquid scintillators (WbLS) are attractive neutrino detector materials because they allow the separation of Cherenkov and scintillation signals. Using WbLS large-scale neutrino experiments can benefit from both directional reconstruction and enhanced low-energy efficiency. Brookhaven National Lab (BNL) has long-standing expertise in developing WbLS and metal-doped liquid...
Advances in additive manufacturing (AM) techniques, such as 3D printing, can provide an attractive solution for addressing the instrumentation needs for the next generation of HEP experiments. Benefits of AM methods include production of low radioactivity components as well as enabling new geometries and multi-material compositions. These simples to highly complex geometries may be...
Hybrid neutrino detectors, capable of leveraging both Cherenkov and scintillation signals simultaneously, have the potential to revolutionize the field of low- and high-energy neutrino detection, offering unprecedented event imaging capabilities and resulting background rejection. These performance characteristics would substantially increase sensitivity to a broad program of fundamental...
We have used the TOPAS Geant4-based package to write a parametric simulation of the pattern recognition and image reconstruction of a whole-body TOF-PET camera employing a liquid scintillator with low atomic number (Z) as the active medium rather than conventional high-Z crystals, and with large-area MCP-based photodetectors for determination of Time-of-Flight. For 511 keV gamma rays Compton...
Future collider experiments will require particle tracking performance beyond the reach of existing technologies. A novel type of scintillation material based on InAs quantum dots (QD) embedded within GaAs has been developed in pursuit of satisfying the demands of next generation 4D trackers. The epitaxially grown structure utilizes QDs as luminescence centers with radiative timescales on the...
Following the priority research directions documented in the 2019 DOE Basic Research Needs Study on Instrumentation [1] for future HEP calorimetry novel inorganic scintillators are under development at the Caltech Crystal Lab. They are radiation hard LYSO:Ce crystals and LuAG:Ce ceramics, ultrafast BaF2:Y crystals and Lu2O3:Y ceramics, and cost-effective heavy scintillating crystals and...
The Electron Ion Collider (EIC) is a new facility that has been proposed in the US to study the structure of nuclear matter in the gluon dominated regime of QCD using Deep Inelastic Scattering (DIS) with precision electromagnetic probes. The EIC will utilize the existing RHIC collider and a new Electron Storage Ring to provide beams of polarized electrons in the energy range from 2.5-18 GeV to...
The Electron-Ion Collider (EIC) will be an experimental facility to explore the gluons in nucleons and nuclei, shedding light on their structure and the interactions within. Physics goals, detector requirements, and technologies at the EIC are outlined and discussed in the EIC community White Paper and Yellow Report. In particular, for the barrel electromagnetic calorimetry, the electron...
The proton endcap ElectroMagnetic Calorimeter (pECal) at EIC is essential for measuring jets in the hadron-going direction, identifying the $\pi^0$ decay photons, and $e$/$\pi$ separations. The pECal requires to have a good energy resolution and fine granularity. It is planned to be a sampling calorimeter. The current design of pECal is a W-powder/ScFiber (W/ScFi) detector initially developed...
The Electron Ion Collider (EIC) is the next Nuclear Physics flagship experiment to be constructed at Brookhaven National Lab over the next decade. The EPIC detector will be the first experiment at the EIC dedicated to detailed studies of nuclear structure in electron-proton and electron-ion collisions.
The ambitious physics program of the EIC requires a high performance hadronic...
A high-granularity calorimeter insert based on SiPM-on-tile technology for the EIC
One of the key requirements for EIC detectors is to have tracking and full calorimetry up to $\eta$=4.0. The forward region (3<$\eta$<4) poses multiple challenges, including those arising from the EIC beam-crossing angle. We present a design for a calorimeter insert (CALI) that is based on the SiPM-on-tile...
Calorimetry in high-radiation environments is particularly challenging. Examples
are forward regions of lepton and hadron collider-detectors. A viable choice is to construct a sampling calorimeter with radiation-hard active media. We have developed a radiation-hard, fast, robust and cost effective technique: secondary emission calorimetry(SE cal). Secondary emission from metal oxide films on...
Scintillation materials can convert high-energy rays into visible light. Generally, solid scintillator can be divided into crystal scintillator, plastic scintillator, glass scintillator and ceramic scintillator. Compared with crystal scintillators, the glass scintillator has many advantages, such as a simple preparation process, low cost, and continuously adjustable components. Therefore,...
The FoCal detector at the ALICE experiment at the CERN LHC is designed for studying a wide range of physics observables to probe non-linear QCD dynamics in an unexplored kinematic region. FoCal is a high-granularity calorimeter covering the pseudorapidity interval 3.4 < η < 5.8, and is scheduled to start operations in Run 4. The FoCal detector design has been optimized for studying prompt...
The development of Water-based Liquid Scintillator (WbLS) for use in future particle physics experiments requires that a practical method be found for removing optical and radiological contaminants while not destroying the micelle-encapsulated LS. In addition, loading of some isotopes (e.g. Gd, Li, Te) may be desirable in order to expand the science scope of such detectors into solar physics...
