Instrumentation and Detectors Papers of the Week

We present the first search for fixed-polarization dark photon (DP) dark matter in the 44-52$\mu\mathrm{eV}$ mass range, corresponding to 10.7-12.5GHz.

We present an optical acceptance test framework specifically designed for the calorimeter, providing comprehensive link and slow-control validation of installed FireFly modules under realistic operating conditions.

In this work, we define a regional anomaly score by summing the squared latent coordinates of the same flow within small detector regions around the point where the particle enters the calorimeter, with the threshold set using background showers alone.

The electron constitutes the beta radiation detected in this work, while the accompanying antineutrino motivates future extensions toward neutrino detection.

We formalize this: records form a lattice on which information is monotone; thinning a Poisson record scales Fisher information exactly by the retention; clustered records read out as sums cost the 1/(1+cv^2); and the quadrature budget a/sqrt(E) (+) b is the floor of every summed readout.

We present a fast self-triggering and segment-fitting algorithm that identifies cosmic muons and reconstructs their directions using a small-diameter Monitored Drift Tube (sMDT) chamber without an external trigger detector.

At a deep (800-1000 m) and a shallow (65 m) CO2 storage site, each approach reduces the computing time about 700-fold, and the filtered simulation gives the same hit rate as a full one, as long as the margin exceeds the muons' sideways scattering drift.

Here, we present inverse low-gain avalanche diode (iLGAD) sensors integrated with a thin entrance window, demonstrating single-photon resolution down to 390 eV (below the Nitrogen K-edge) with a signal-to-noise ratio of 5.

We present the design of COMIRA, a compact magnetic spectrometer for space radiation measurement.

In this contribution, we evaluated ILGAD sensors bump-bonded to 25 {\mu}m pitch charge-integrating MÖNCH chips at a laser-driven soft X-ray source.

To this end, we designed a new electrode structure using Garfield++ simulations and fabricated a triaxial $\mu$-PIC based on through-glass-via (TGV) technology.

A unified framework for track reconstruction in the ACTAR Time Projection Chamber (ACTAR TPC) is presented, designed to address the specific challenges of direct-reaction and resonance-elastic scattering experiments involving exotic nuclei.

Sensitivity analyses cover dark-count level, heterogeneity, detector model and random seed.

A position reconstruction method based on the light-yield distribution was developed for both single- and multi-particle events.

This work presents a UVM-based verification strategy that identified 260 design errors and summarizes key lessons from ASIC sign-off.

A turn-on study identifies capacitor charging at Stage 3 as the main cause of inrush currents triggering Stage 2 overcurrent protection.

We present the engineering development, gas diagnostics, and spectroscopy data from our hydrogen plasma.
