Design and modeling of an integrated flywheel magnetic suspension for kinetic energy storage systems
The paper presents a novel configuration of an axial hybrid magnetic bearing (AHMB) for the suspension of steel flywheels applied in power-intensive energy storage systems. The combination of a permanent magnet (PM) with excited coil enables one to reduce the power consumption, to limit the system volume, and to apply an effective control in the presence of several types of disturbances. The electromagnetic design of the AHMB parts is carried out by parametric finite element analyses with the purpose to optimize the force performances as well as the winding inductance affecting the electrical supply rating and control capability. Such investigation considers both the temperature dependence of the PM properties and the magnetic saturation effects. The electrical parameters and the force characteristics are then implemented in a control scheme, reproducing the electromechanical behavior of the AHMB-flywheel system. The parameter tuning of the controllers is executed by a Matlab/Simulink code, examining the instantaneous profiles of both the air-gap length and the winding ampere-turns. The results of different dynamic tests are presented, evidencing the smooth air-gap changes and the optimized coil utilization, which are desirable features for a safe and efficient flywheel energy storage
Radon mitigation during the installation of the CUORE decay detector
CUORE - the Cryogenic Underground Observatory for Rare Events - is an
experiment searching for the neutrinoless double-beta () decay
of Te with an array of 988 TeO crystals operated as bolometers at
10 mK in a large dilution refrigerator. With this detector, we aim for a
Te decay half-life sensitivity of y
with 5 y of live time, and a background index of
counts/keV/kg/y. Making an effort to maintain radiopurity by minimizing the
bolometers' exposure to radon gas during their installation in the cryostat, we
perform all operations inside a dedicated cleanroom environment with a
controlled radon-reduced atmosphere. In this paper, we discuss the design and
performance of the CUORE Radon Abatement System and cleanroom, as well as a
system to monitor the radon level in real time.Comment: 10 pages, 6 figures, 1 tabl

Getting beyond peeing and pronouns: living non-binary gender in higher education
Non-binary people make up just over half the UK trans population and younger people are more likely to identify as non-binary than those over 35. Despite this increasing recognition, non-binary identities and experiences continue to be widely misunderstood. Similarly, if university trans inclusion policies focus solely on models of binary or medical transition, they will not fully address the needs of non-binary students. In the context of an increased focus on the participation and success of marginalized social groups in higher education, and a social and political backlash against equality, diversity and inclusion work, questions of how non-binary students thrive in universities are pressing. Non-binary inclusion and experiences in higher education have received little dedicated attention. This article draws on data from the largest survey to date of non-binary students in the United Kingdom and begins to fill those gaps. We highlight the prominence in the survey of issues around āpeeingā and āpronounsā in the lived experiences of non-binary students and demonstrate the detrimental impact of the lack of recognition on studentsā learning and lives at university. We conclude universities must get beyond āpeeing and pronounsā to reimagine higher education as an accessible and inclusive space
Calibration sources for the LEGEND-200 experiment
In the search for a monochromatic peak as the signature of neutrinoless double beta decay an excellent energy resolution and an ultra-low background around the Q-value of the decay are essential. The LEGEND-200 experiment performs such a search with high-purity germanium detectors enriched in 76Ge immersed in liquid argon. To determine and monitor the stability of the energy scale and resolution of the germanium diodes, custom-made, low-neutron emission 228Th sources are regularly deployed in the vicinity of the crystals. Here we describe the production process of the 17 sources available for installation in the experiment, the measurements of their alpha- and gamma-activities, as well as the determination of the neutron emission rates with a low-background LiI(Eu) detector operated deep underground. With a flux of (4.27Ā±0.60statĀ±0.92syst)Ć10ā4 n / (kBqā
s), approximately one order of magnitude below that of commercial sources, the neutron-induced background rate, mainly from the activation of 76Ge, is negligible compared to other background sources in LEGEND-200
