Recent advances in photonic and radiation sensors and detectors has allowed high quality and high
timing resolution measurements of phenomena related to high energy physics, nuclear physics and
astro- particle physics experiments. Examples of such sensors include silicon photomultipliers (SiPM),
multi-channel plate photomultiplier tubes (MCP-PMTs), large area picosecond photo...
We are going to discuss the CYGNO/INITIUM experiment, a recent Dark Matter (DM) project focused on developing a new and innovative approach for directional DM searches: a high precision, optically readout, 3D tracking gaseous Time Projection Chamber. The searches will focus on the detection of low mass (0.5-50 GeV) WIMPS and, eventually, solar neutrino spectroscopy. For its detection medium,...
The current ATLAS Inner Detector will be replaced with a new all-silicon Inner Tracker (ITk) to cope with the high-density environment during High Luminosity LHC (HL-LHC). The innermost part of the ITk will comprise a state-of-the-art pixel detector. The individual modules of the Inner Tracker pixel detector incorporate silicon sensors using diverse technologies, with the sensors readout using...
Research at the frontier of particle physics often requires the search for phenomena of extremely low probability of occurrence, the so called "rare events". Under this category falls the search for the hypothetical particles potentially composing the mysterious dark matter (DM) of the Universe, like e.g. the Weakly Interacting Massive Particles (WIMPs) or the axions. Being low energy events...
Diode detectors for photons and photon energy use Si, Ge and many others. For very low energy photons, Si(Ge) pair energy Ep=3.6 eV(2.98eV) are too large for many applications. Semiconductor materials used for vacuum photocathodes have much lower Ep: Cs3Sb (S-11)~2eV pair energy; Cs-Ag-O (S-1) averaged pair energy/work function Ep=0.7 eV, and studies have shown that in small patches that the...
The characterization and minimization of backgrounds from primordial radionuclides and their long-lived progeny is critical to accurately simulate background and achieve sufficient signal-to-noise for a detection in rare-event physics detectors, like direct detection of dark matter and neutrinoless double beta decay investigations. Current inductively coupled plasma mass spectrometry assay...
Two important limitations hinder searches for low-mass dark matter and the reactor neutrino coherent scattering: Backgrounds and the threshold. SuperCDMS experiment is addressing both challenges by using two complementary and different technologies. Using simultaneous ionization and phonon measurement, SuperCDMS gains even-by-event background discrimination and addresses the backgorund...
Line-intensity mapping (LIM) at millimeter wavelengths is a powerful emerging probe of the large-scale structure of the Universe, but achieving meaningful constraints on cosmological parameters with LIM requires focal planes with orders of magnitudes more detectors than existing instruments. SPT-SLIM is an upcoming experiment to demonstrate LIM observations of CO at 0.5 < z < 2.0 using on-chip...
Coherent elastic neutrino-nucleon scattering (CEvNS) offers a new avenue in searching for physics beyond the Standard Model. The Ricochet neutrino experiment aims to detect CEvNS at the Institut Laue–Langevin (ILL) nuclear reactor. One of the two cryogenic detector arrays employs a modular TES (Transition Edge Sensor) based readout strategy. This poster will introduce the latest measurement...
Funded by its Office of the President, a consortium of University of California
affiliated institutions has been exploring the use of electronic-grade diamond
sensors for applications in extreme environments, including settings involving
high fluences of hadronic particles (in excess of 10^16 Neq/cm^2), high instantaneous flux (approaching 100 J / cm^2 of deposited energy) and/or high...
We present a novel methodology for application to neutron imaging detectors equipped with boron layers. State of the art boron coated neutron detectors are equipped with 10B films deposited on substrate plates with combined thickness larger than the range of the fission fragments emitted upon a neutron capture reaction. Since these fission fragments are emitted back-to-back, one of them (at...
Searches for sub-GeV dark matter direct detection have been dominated by dark matter electron scattering. However, an inelastic scattering process known as the "Migdal effect", in which an atomic electron is ionized during a nuclear recoil, has been shown to greatly enhance the sensitivity of nuclear recoil experiments to sub-GeV dark matter. In this talk an experimental strategy to calibrate...
We will discuss recent progress in making sub-keV nuclear recoil calibrations practical in a university lab environment. First, we will describe a 124SbBe (gamma,n) neutron source in which a novel Fe shielding method suppresses the outgoing gamma flux while allowing the unmoderated escape of the 24keV neutrons. Second, we will describe a method to moderate and then filter neutrons from a...
The high luminosity Large Hadron Collider (HL-LHC) will collide particles at unprecedented rates to search for new physics and make high precision measurements to challenge the standard model. The increase in granularity of the detectors and the background rates pose high demands for the materials of charged particle tracking detector support structures. Tracking detectors at current (and...
