There is a new service from HSE to do IAQ (indoor Air Quality) assessments, we should ask them to do this for any/all areas where we have 3D printers. Do you have a list of printers and where they are located? I’m happy to make the request as we’ll have other experiments that also need this.

Title: ARIES: A Next-Generation β-Tagging Detector with Sub-Nanosecond Timing and High Spatial Resolution
Speaker: Victoria Vedia (CERN)
Abstract: The development of state-of-the-art instrumentation is essential to unlocking the full scientific potential of radioactive ion beam facilities, where a powerful approach combines large HPGe arrays with auxiliary particle detectors to enable high-precision, correlated decay studies.
ARIES is a next-generation ancillary β-tagging detector, which integrates high β-detection efficiency, sub-nanosecond timing resolution, fine spatial granularity, and high data throughput within a single, compact system.
Designed to overcome traditional trade-offs between timing, efficiency, and spatial resolution, ARIES enables precision β–γ angular correlations, fast-timing lifetime measurements, and high-statistics decay spectroscopy. Its modular architecture and optimized geometry significantly extend the reach of studies of exotic nuclei far from stability and its picosecond-level timing and rate capabilities exceeding 20 MBq sets a new benchmark for ancillary detector performance.
In this talk, I will present the design, implementation, and performance of the ARIES detector.
