Abstract In this work we report the realization of first low-threshold cryogenic detector that uses diamond as absorber for astroparticle physics applications. We tested two 0.175 g CVD samples, each instrumented with a W-TES. The sensors showed transitions at about 25 mK. present performance detectors and highlight best performing one, where obtained an energy threshold low 16.8 eV. This promi...
In threshold-based anomaly detection, we want to tune the threshold of a detector achieve an acceptable false alarm rate. However, tuning is often non-trivial task due unknown output distributions. A that provides rate equivalent specific quantile distribution. Therefore, use estimators based on order statistics estimate threshold. The estimation quantiles from sample data has more than century...
It is a challenge to implement loss-of-signal (LOS) circuit with wide threshold voltage range that insensitive temperature. This paper presents new wide-range threshold-programmable LOS detector full temperature compensation for application in 25Gb/s high-speed optical communication receivers. The programmable of the achieved by adjusting peak and gain variable amplifier (VGA). detection accura...
An x-ray detector for a solar axion search was developed. The detector is operated at 60K in a cryostat of a superconducting magnet. Special care was paid to microphonic noise immunity and mechanical structure against thermal contraction. The detector consists of an array of PIN photodiodes and tailor made preamplifiers. The size of each PIN photodiode is 11 × 11 × 0.5 mm and 16 pieces are used...
In this paper we report quantitative measurements of the imaging performance for the current generation of hybrid pixel detector, Medipix3, used as a direct electron detector. We have measured the modulation transfer function and detective quantum efficiency at beam energies of 60 and 80keV. In single pixel mode, energy threshold values can be chosen to maximize either the modulation transfer f...
