Solar Wind an overview | ScienceDirect Topics

Nov 27, 1999· Solar wind is an ionized gas made up primarily of protons and electrons with minor ions in amounts similar to those in the corona The electrons and ions are very tightly bound to lines of magnetic flux, again like the coronal plasma in streamers However, the magnetic field in the solar wind is relatively weak and thus is carried along by the solar windThe coil and liquid helium is kept in a large dewar The typical volume of liquid Helium in an MRI magnet is 1700 liters In early magnet designs, this dewar was typically surrounded by a liquid nitrogen (774K) dewar which acts as a thermal buffer between the room temperature (293K) and the liquid heliumCHAPTER9
