Young stars ejecting plasma could give us clues into the Sun’s past Kyoto, Japan — Down here on Earth we don’t usually notice, but the Sun is frequently ejecting huge masses of plasma into space. These are called coronal mass ejections (CMEs). They often occur together with sudden brightenings called flares, and sometimes extend far enough to disturb Earth’s magnetosphere, generating space weather phenomena including auroras or geomagnetic storms, and even damaging power grids on occasion. Scientists believe that when…

In the production of cavity resonators, the interior field distribution is measured in order to verify that quality and efficiency are being maintained.<br>
The newly developed technology is particularly suitable to be used in superconducting cavity resonators. In comparison to conventional methods, the new method is also suitable to be implemented at operating temperatures of up to 4K. For this reason the calibration is carried out under realistic operating conditions. Furthermore, the key characteristic is that measuring takes place over the entire length of the cavity resonator. Changes in the field are also identified during the cooling period….
