In low duty cycle machines, such as linear and muon colliders, collision happen only in a small fraction of the total operational time. Currently, most of the developments of Monolithic Active Pixel Sensor (MAPS) focus on circular colliders, with a continuous time analog front-end. In this contribution we propose a time-variant analog front-end, which, when operated synchronously with the...

Searches for 1-10 GeV dark matter particles with liquid xenon TPCs such as LZ, XENONnT and PandaX-4T are presently limited by instrumental backgrounds consisting of accidental photon coincidence. We have investigated this pathology and conclude that the dominant source of the photons, which follow each particle interaction, is fluorescence of the quartz windows of the photomultiplier tubes....

Grace Bratrud (Northwestern University)09/10/2025, 14:40RDC 7 Low-Background DetectorsParallel session talk
Recent work has shown that ionizing radiation incident on a superconducting qubit chip can cause phonon excitation and trapped charges. The phonons can generate non-equilibrium quasiparticles in the superconductor, which can tunnel across the junction and interact with the qubit energy. Trapped charges change the electric field environment in nearby qubits and are seen as charge noise in...

In advanced detectors, we observe events of stored energy releases, as well as energy accumulation and delayed release dynamics. Spontaneous burst emission of phonons, photons, and quasiparticles produces excess backgrounds in dark matter detectors and correlated quantum errors and decoherence in quantum information devices- in the same way as external particles. These effects are now observed...

In pursuit of a quantum computer, there have been many proposals of qubits that take advantage of quantum systems, from solid-state systems to trapped ions. A particularly promising candidate is the transmon, a qubit based on a superconducting resonator with a Josephson Junction and optimized to have reduced sensitivity to charge noise. It is well-known that these types of qubits suffer from...

To date, all light mass dark matter calorimeters have measured a low energy, non-ionizing background whose rate decreases with time since cooldown. Such bursts have recently also been seen to be the dominant source of parity flipping in superconducting QUBITs. In this talk, we will summarize recent work to understand the source of this background where we correlated the measured burst rate to...
