We present a realistic 3D simulation workflow for pixel detectors, with emphasis on TCAD modeling of Timepix and CMS CROC pixel sensors and its connection to Monte Carlo-based synthetic data generation. Detailed electric-field and charge-transport simulations are used to model detector response, while Allpix Squared provides event-level Monte Carlo simulation and pixel-level observables such...

Patterns of charge deposited in pixelated particle tracking detectors are rich with kinematic information that is lost to ever increasing bandwidth constraints in high-luminosity environments. On-sensor inference of track geometry at the collision rate will grant next-generation triggering algorithms access to regions closer to the interaction point than ever before. We evaluate the fidelity...

Pixelated tracking detectors are integral to contemporary collider experiments. For forthcoming colliders, 4D pixel detectors that integrate high spatial resolution (<50 ยตm) and high temporal resolution (<30 ps) present a compelling solution to manage the extreme particle multiplicities prevalent in environments such as a Muon Collider. The 4D Fabric initiative is dedicated to the development...

The Selena experiment aims to search for neutrinoless double beta decay in โธยฒSe using hybrid amorphous selenium (aSe)/CMOS pixel sensors, in which a thick aSe layer is deposited directly over a fine-pitch CMOS readout chip. A high-voltage is applied across the aSe to drift and collect ionization. Current R&D devices are Topmetal-Se bare die, featuring 100ร100 pixel array with exposed metal...

Low Gain Avalanche Detectors (LGADs) are characterized by a fast rise time (~500ps) and extremely good time resolution (down to 17ps), and the potential for a very high repetition rate with ~1 ns full charge collection. For the application of this technology to near-future experiments such as e+e- Higgs factories (FCC-ee), the ePIC detector at the Electron-Ion Collider, or smaller experiments...

The advent of Low-Gain Avalanche Diodes (LGADs) and AC-coupled Low-Gain Avalanche Diodes (AC-LGADs) as candidate technologies for four-dimensional tracking has moved part of the reconstruction burden onto the analog waveforms of the sensor, in which the charge shared between electrodes encodes the impact position well below the electrode pitch. Recovering that position is a continuous,...

The PIONEER experiment at the Paul Scherrer Institute (PSI) will observe rare pion decay processes; in its first phase, it will provide a sensitive test of the Standard Model by measuring the branching ratio for pion decays directly into positrons ($\pi^+ \to e^+ \nu_e$) with a precision of 0.01%. We are developing a demonstrator for the active target (ATAR) system, a key novel component of...

LGADs have an internal gain mechanism that allows for a timing resolution on the scale of tens of picoseconds within a 50 micron active thickness. However, they have been optimized for use with minimum ionizing particles (MIPs) at institutions like the LHC. In this talk, I will discuss recent studies performed with the University of Washington's tandem accelerator on LGAD responses in the...

Thin-film semiconductor sensors represent a class of particle detectors that exploit scalable deposition techniques to extend the range of active materials beyond silicon and to ultimately enable large-area, low-mass sensor fabrication on flexible substrates. The active material may be deposited as a standalone film, or directly onto a CMOS readout ASIC, enabling monolithic-like hybrid...
