We summarize the recent progress of Axion Longitudinal Plasma Haloscope (ALPHA) Consortium, a new experimental collaboration to build plasma haloscope search for axions and dark photons. The is novel method detection resonant conversion light matter ALPHA will be sensitive QCD over almost decade parameter space, potentially discovering resolving strong $CP$ problem. Unlike traditional cavity haloscopes, which are generally limited in volume by Compton wavelength matter, haloscopes use wire...
Abstract A plasma haloscope has recently been proposed as a feasible approach to extend the search for dark matter axions above 10 GHz (≈40 eV), whereby microwave cavity in conventional axion is supplanted by wire array metamaterial. Since frequency of metamaterial determined its unit cell, and thus bulk property, resonator any can be made arbitrarily large, contrast which incurs steep penalty volume with increasing frequency. To assess actual potential this concept practical haloscope,...
In this paper, we have developed a methodology to estimate the spatiotemporal distribution of radiation air dose rates around Fukushima Daiichi Nuclear Power Plant (FDNPP). our exploratory data analysis, found that (1) temporal evolution is composed log-linear decay trend and fluctuations are spatially correlated among adjacent monitoring posts; (2) slope environmental can be represented as function apparent initial rates, coordinate position, land-use type, soil type. From these...
Metamaterials based on regular two-dimensional arrays of thin wires have attracted renewed attention in light a recently proposed strategy to search for dark-matter axions. The metamaterial-based resonator concept was specifically motivated by recent stringent predictions the axion mass one cosmological scenario, which are expected improve further near future. When placed external magnetic field, such metamaterials facilitate resonant conversion axions into plasmons their plasma frequency....
Metamaterials based on regular two-dimensional arrays of thin wires have attracted renewed attention in light a recently proposed strategy to search for dark matter axions. When placed the external magnetic field, such metamaterials facilitate resonant conversion axions into plasmons near their plasma frequency. Since axion mass is not known priori, practical way tune frequency metamaterial required. In this work, we studied system two interpenetrating rectangular wire lattices where...
It is now known explicitly how to calculate the pressure losses due a developed flow in pipe. As for pipe system, simplicity, minor caused by valves, elbows, enlargements, inlets, outlets, and other fittings was considered be ignorable when compared with frictional losses. However, actually, this not always case. In work designing safety rods next generation of fast reactor, inner structure which makes large part contribution drop liquid sodium through them, should carefully. case, T-joint...
The present work was undertaken to evaluate the sedimentation rate of sodium aerosol in a hypothetical fire accident China Experimental Fast Reactor (CEFR). In accident, which hazardous for facility and people as result its chemical property radioactivity, must be carefully evaluated. this publication, physical characteristics particles well factors that influence during transport is attempted analysed. Besides, simplified model given calculate when getting through ventilation system CEFR....
A plasma haloscope has recently been proposed as a feasible approach to extend the search for dark matter axions above 10 GHz ($\sim$ 40 $μ$eV), whereby microwave cavity in conventional axion is supplanted by wire array metamaterial. As frequency of metamaterial determined its unit cell, and thus bulk property, resonator any can be made arbitrarily large, contrast which incurs steep penalty volume with increasing frequency. We have investigated basic properties metamaterials through $S_{21}$...
