Three years have passed since the start of the 1ton Water-based Liquid Scintillator (WbLS) at Brookhaven National Lab. This detector is by-far the longest running tonne-scale WbLS detector in the world. Since it started, we have completed two phases and a paper has been published showing the initial performance. In the latest phase, phase-III, we initiated a multi-step WbLS injection from 0.3%...
Water-based Liquid Scintillator (WbLS) is an innovative material for constructing large-scale detectors in neutrino and dark matter research. The tunable light yield, enabled by an inline circulation system, allows for flexible detector optimization for different physics searches. With adequate photosensor coverage, detecting low-intensity light can reconstruct the momentum of energetic...
Future kilotonne-scale neutrino detectors, such as Theia, aim to leverage new and emerging technologies to simultaneously measure Cherenkov and scintillation light, to enable rich science programs and nonproliferation efforts. To achieve these goals, these hybrid detectors will exploit fast timing photodetectors, novel liquid scintillators, and spectral sorting techniques.

Since the entry to the precision era for the nuclear and high-energy physics communities, excellent particle detection capability is highly demanded for each part of the detection system. A homogeneous EM-Calorimeter could provide excellent energy resolution for electrons and photons in a wide dynamic range allowing rapidity coverage, particle containment and granularity. However, concerns of...
Hybrid neutrino detectors utilize both Cherenkov and scintillation light for event detection and reconstruction - leveraging the lower energy threshold of pure scintillation emission and the enhanced direction resolution afforded by water. The benefits of hybrid technologies provide for advancements in both fundamental physics research and in nuclear nonproliferation applications. Benchtop...
Positron Emission Tomography (PET) scanners detect gamma rays resulting from a tracer chemical like fluorine-18.. These gamma rays have been detected in a pixelated Liquid Argon Time Projection Chamber (LArTPC) optimized for neutrino physics studies. These tests have in part motivated the optimization and design of a LArTPC for application in PET. This talk will present the simulations and...
The future Deep Underground Neutrino Experiment (DUNE) experiment will require unprecedented levels of precision to reach its physics goals.

The Americium-Beryllium (AmBe) source is well-known for the use of gamma and neutron detection calibration in large-scale liquid detectors. At Brookhaven National Lab, we designed a new type of AmBe source combining with Lutetium–yttrium oxyorthosilicate (LYSO) crystal. By combining them, the single PE calibration for the PMTs in the liquid detector can be done with the intrinsic LYSO crystal...
Coping with the higher collision rates of the High-Luminosity Large
Hadron Collider (HL-LHC) requires the development of new ATLAS Liquid

designed to read out the full granularity of the calorimeter with full
precision over the 16-bit dynamic range at...
The Liquid Argon Calorimeters are employed by ATLAS for all electromagnetic calorimetry in the pseudo-rapidity region |eta| < 3.2, and for hadronic and forward calorimetry in the region from |eta| = 1.5 to |eta| = 4.9.
They also provide inputs to the first level of the ATLAS trigger. In 2022 the LHC started its Run-3 period with an increase in luminosity and pile-up of up to 60 interactions...

In particle physics, calorimetry refers to the detection of particles and measurement of their properties by the complete absorption of the particle’s energy in a bulk of a matter, referred to as a calorimeter. Calvision is a consortium of universities and Department of Energy laboratories focused on advancing state-of-the-art calorimetric measurements for all types of particles with a higher...
Homogeneous inorganic scintillator-based calorimeters are the gold standard for electromagnetic energy resolution, but often degrade the hadronic energy resolution achievable at colliders.
