摘要

Over the past several decades since the invention of the first biosensor based on the Clark-oxygen electrode for glucose, the instrument most used for measuring for biosensor devices has been the potentiostat, and there have been thousands of published papers on electrochemical biosensors using the potentiostat. Here, we show for the first time a comparison between a potentiostat and a source measure unit (SMU) for signal generation in a biosensing measurement of glucose. The results demonstrated that both a potentiostat and a SMU could provide excellent sensing performances, though the results were slightly difference. We expect that this work can open up exciting opportunities for fundamental studies on the measurement methods of biosensing devices, as well as for a variety of applications for using biosensing devices in healthcare, environmental monitoring, and defense.

Calibration sources for the LEGEND-200 experiment

L. Baudis, G. Benato, E. M. Bond, P. J. Chiu, S. R. Elliott, R. Massarczyk, S. J. Meijer, Y. Muller

Summary: In the LEGEND-200 experiment, excellent energy resolution and ultra-low background around the Q-value are crucial for searching for monochromatic peaks as the signature of neutrinoless double beta decay. Custom-made Th-228 sources with low neutron emission rates are used to determine and monitor the stability of the energy scale and resolution of the germanium detectors. The neutron-induced background rate, mainly from the activation of Ge-76, is negligible compared to other background sources in LEGEND-200, with a flux approximately one order of magnitude lower than commercial sources.

Summary: The SuperNEMO experiment aims to search for neutrinoless double-beta decay and study the Standard-Model double-beta decay process. The SuperNEMO Demonstrator Module will be calibrated using 42 Bi-207 calibration sources for accurate energy response, and a novel method using Timepix pixel detectors has been proposed for precise measurement of the sources' geometry. Selection of high-quality sources with central positioning is crucial for calibration.

Summary: SNO+ is a large-scale liquid scintillator experiment located approximately 2 km underground in SNOLAB, Sudbury, Canada, with the primary goal of searching for neutrinoless double beta decay. The experiment measured the optical properties of the detector in situ using a deployed light diffusing sphere to improve the detector model and energy response uncertainties. The calibrated detector model was validated using a deployed tagged gamma source, showing a 0.6% variation in energy scale across the primary target volume.

Characterization of a CMOS pixel sensor for charged particle tracking

L. Li, L. Zhang, J. N. Dong, J. Liu, M. Wang

Summary: A prototype CMOS pixel sensor named Supix-1 was fabricated and tested to investigate its feasibility for a pixelated tracker for the proposed Circular Electron-Positron Collider (CEPC). The sensor, fabricated with a 180 nm CMOS Image Sensor (CIS) process, showed satisfactory noise level and charge collection performance for pixels as large as 21 x 84 µm. The study demonstrates that CMOS pixel sensors with enlarged pitches using CIS technology can be used in tracking for upcoming collider detectors like the CEPC.
