Sub-Kelvin ac magnetic susceptometry.
Designing an apparatus for experiments that operate deep into the milliKelvin regime requires a careful selection of materials and construction techniques, and often entails balancing mutually contradictory requirements. In the case of magnetic susceptibility measurements, this involves choosing materials that realize both high thermal conductivity for good heat sinking and low electrical condu...
متن کاملSensitive High Frequency AC Susceptometry in Magnetic Nanoparticle Applications
We report on the development of a sensitive high frequency susceptometer capable of measuring in the frequency range from 25 kHz up to 10 MHz with a volume susceptibility sensitivity of 3.5×10 at 100 kHz corresponding to about 0.3 % of the measured AC susceptibility. In combination with the previous reported DynoMag system capable of measuring dynamic magnetic properties in the range from 1 Hz ...

متن کاملAntiproton-Hydrogen annihilation at sub-kelvin temperatures
The unique features of the LEAR (low-energy antiproton ring) facility at CERN made recently possible the synthesis of few antihydrogen atoms [1]. This effort would be pursued with the antiproton deccelerator (AD) project [2] and would make possible the storage of sensible amounts of antihydrogen. This project reinforces the already active interest to investigate several theoretical and experime...
متن کاملSPICA/SAFARI Sub-Kelvin Cryogenic Chain
SPICA, a Japanese led mission, is part of the JAXA future science program and is planned for launch in 2018. SPICA will perform imaging and spectroscopic observations in the 5 to 210 mm waveband. The SPICA payload features three instruments, one of which, SAFARI, is developed by a European based consortium. SPICA’s distinctive feature is to use an actively cooled telescope down to 4 K. In addit...
