High fidelity measurements of low energy particle tracks are vital for physics applications where reconstructing directionality and event topology is required, such as in searches for dark matter, the Migdal effect, and new physics in CEvNS experiments. Low pressure negative ion drift (NID) time projection chambers (TPC) utilizing micro-pattern gas detectors (MPGDs) provide a unique and...
Imaging the detailed 3D topology of ionization in detectors is broadly desirable in nuclear and particle physics. Of particular interest is the directional detection of nuclear recoils from neutrinos or dark matter, which may prove critical for probing dark matter beneath the neutrino fog and affirming its galactic origin. Gaseous time projection chambers (TPCs) can provide the required...
I will discuss a new collaboration between the University of Hawaii and Berkeley Lab dedicated to developing an "ideal" gaseous TPC readout technology based on integrated grid amplification and silicon pixel readout combined with ML/AI-capable frontend cluster discrimination.
A novel heavy-ion particle-identification (PID) device based on optical-readout energy-loss measurement (ELOSS) is presented. The device is designed to identify the atomic number of the reaction fragments that reach the focal–plane detector system of the S800 spectrograph at the Facility for Rare Isotope Beams (FRIB).
The new instrument consists of a large volume filled with xenon gas at...
High pressure gaseous argon time projection chambers (HPgTPC) is crucial for many applications, including neutrino oscillation analyses, and rare event searches such as coherent elastic neutrino-nucleus scattering (CEvNS) and low-energy nuclear recoil detection. Current R&D efforts are focused on testing gas electron multipliers (GEMs) in high-pressure environments, which is critical for...
Scaling neutrinoless double beta decay experiments to the 100 ton or kiloton scale seems most plausible, at least from an instrumentation point of view, if we aim for a large TPC. However, the lack of a xenon supply chain is a bottleneck. In this talk, we will discuss possible alternatives TPC gases, including SeF6 efforts, and our efforts to identify alternative non-electronegative gases. ...
We are working on R&D studies of a straw tracker that could be used as an inner tracker for the FCC-ee experiments. The straw tracker offers the advantage of a low material budget and a single-hit resolution of 100-120 microns per straw. With about 100 layers, the straw tracker will play a pivotal role in pattern recognition, particle identification, and long-lived particle searches. Straws...
Circular Electron Positron Collider as a Higgs and high luminosity Z factory, the accelerator Technical Design Report has been released in the end of 2023. The baseline design of a detector concept consists of a large 3D tracking system, which is a high precision (about 100μm) spatial resolution Time Projection Chamber (TPC) detector as the main track embedded in a 3.0T solenoid field,...
The possibility to realize a second detector at the IP8 position of Electron Ion Collider (EIC) is of great importance. It is aimed to provide complementarity and reference for the physics measurements of the future ePIC detector at the EIC with the possibility of extended physics measurements.
Time Projection Chamber (TPC) with GridPix readout is one of the most attractive options as it...
The future Electron-Ion Collider (EIC) at Brookhaven National Laboratory will collide polarized electrons with polarized proton/ions. The electron – Proton / Ion Collider (ePIC) Experiment is the EIC general-purpose detector aiming at delivering the full physics program of the EIC. This unique environment imposes stringent requirements on the tracking system needed for the measurement of the...
The sPHENIX TPC is a double-sided, GEM-based, gaseous drift detector covering full azimuth and |η| < 1.1. The TPC is instrumented with 624 Front End Electronics (FEE) Cards which perform analogue/digital conversion, pulse shaping, and zero suppression. The FEE cards use 8 SAMPA v5 ASIC chips with shaping time of 80 ns, digitization rate of 20 MHz, and 10-bit adc ouptut for 256 pads each. The...
The sPHENIX experiment completed construction at Brookhaven National Lab's RHIC facility in 2023 and has now completed its first full year of data taking, with a physics program that will probe the nature of QGP through jet, upsilon and open heavy flavor final states over a broad range of pT. The experiment's Time Projection Chamber covers |\eta|<1.1 and full azimuth, and serves as its main...
