Liquid

Oral

Liquid argon is an excellent medium for detecting particles, given its yields and transport properties of light and charge. The technology of liquid argon time projection chambers has reached its full maturity after four decades of continuous developments and is, or will be, used in world class experiments for neutrino and dark matter searches. The collection of ionization charge in these...

Liquid

Oral

The Short-Baseline Near Detector (SBND) is a LArTPC approximately 110 meters from the Fermilab’s Booster Neutrino Beam (BNB) intended to measure neutrino cross sections and aid in excess electron-like neutrino searches.
The electric field inside the SBND-TPC may have distortions due to a number of reasons, such as the space charge effect. The space charge effect comes from the abundance of...

8. Charge-Light Matching of Ambient Low-Energy Activity in the DUNE Near Detector Prototypes

Liquid

Oral

The Deep Underground Neutrino Experiment (DUNE) uses the Liquid Argon Time Projection Chamber (LArTPC) technology to study the neutrino oscillation phenomenon using a long baseline. Beyond neutrino oscillations, the project has a broad and extensive physics program. To ensure precise and accurate spatial and calorimetric resolution in the DUNE LArTPCs, it is important to be able to calibrate...

18. CHARMS250: A Cryogenic Front-End ASIC for Low-Noise Readout of Light or Charge Signals

Electronics

Oral

In this talk we present CHARMS250, a next-generation cryogenic front-end application specific integrated circuit (ASIC) designed in a 65 nm process for low-noise readout of charge or light signals generated within noble liquid time projection chambers (TPCs). The design of CHARMS250 is evolved from the LArASIC chip, which was manufactured in a 180 nm process and has been selected as the first...

36. New candidate polymeric wavelength shifters for noble liquid detectors

WLS

Oral

Scale-up of light collection scheme is a major challenge for the future multi-tonne detectors with surface area of many hundreds or even thousands of square meters. Large-format polymeric wavelength shifting foils are a compelling alternative to traditional vacuum evaporated coatings. Inspired by the success polyethylene naphthalate (PEN), which already finds use in large liquid argon...

29. Quality control of PEN wavelength shifter for DarkSide-20k veto

WLS

Oral

Efficient Wavelength Shifters (WLS) are crucial for liquid Argon (LAr) detectors. As the LAr detectors grow larger in volume, the scalability of WLS becomes an important concern. Tetraphenyl butadiene (TPB), which is the most common WLS in use, becomes impractical for LAr detectors with more than 100 m^2 of surface area due to its high cost and energy requirements.

SiPM

Oral

Silicon PhotoMultipliers (SiPMs) are being explored as potential photosensors employed in detectors operating at low temperatures, such as noble liquid (argon or xenon) experiments used in direct dark matter searches and neutrino physic investigations. Several studies have been conducted to optimize the features of these silicon photosensors, and many tests have been performed to improve the...

11. Mass test setup for the DUNE FD1 SiPMs characterization and first results

SiPM

Oral

The Deep Underground Neutrino Experiment (DUNE) is an upcoming neutrino physics experiment that will answer some of the most compelling questions in particle physics and cosmology. The DUNE Far Detector (FD) exploits silicon photomultipliers (SiPMs) to detect scintillation photons produced by the interaction of charged particles in the liquid Argon time projection chamber (LarTPC). Light...

2. Characterization of the Hamamatsu R12699-106-M4 2-inch Photomultipliers in MarmotX and XAMS

SiPM

Oral

The novel square Hamamatsu R12699-106-M4 2-inch photomultiplier tubes (PMT) feature a four-anode readout in a single low-profile package with a high photocathode coverage (about 75%). This makes them attractive as potential light detectors in future liquid-xenon based direct detection dark matter experiments, such as DARWIN/XLZD. The low-profile reduces buoyancy and therefore the amount of...
