Experimental studies with low energy charged particles
Research interest
Experimental studies on the confinement of charged particles with an electromagnetic field, the production of low energy charged particle beams and the application of the beams for the related plasma physics, beam physics and atomic physics research. (What is a plasma ? )B
A Penning trap can confine charged particles with static electric and magnetic fields. When a single charged particle (electron, positron, proton, antiproton, highly charged ion, etc.) is confined, fundamental properties (g-factor, charge to mass ratio, etc.) of the trapped particle can be measured. When a large number of charged particles is confined as a plasma, various basic properties of the plasma can be investigated. Also, it is applied as a trap based low energy beam source (positrons for example). It is also used for the antihydrogen production at Antiproton Decelerator at CERN.
When there is a pair of magnetic mirrors, it becomes possible to confine both positive and negative charged particles in the same volume. With the use of an improved magnetic mirror trap, the experimental study of electron-positron plasma will be made possible.
This is the collaboration with National Institute of Advanced Industrial Science and Technology (AIST).
