| 21. | There are, however, other types of instabilities, such as velocity-space instabilities in magnetic mirrors and systems with beams.
|
| 22. | The basic idea was to inject high-energy electrons into a magnetic mirror ( the " tank " ).
|
| 23. | Can vary from microseconds ( MEMS and magnetics mirrors ) to tens of seconds for thermally controlled DM's.
|
| 24. | Magnetic mirrors also occur in nature.
|
| 25. | The polywell attempts to confine the ions and electrons through two different means, borrowed from fusors and magnetic mirrors.
|
| 26. | Grad was a critic and supporter of many early fusion schemes including picket fences, magnetic mirrors and Biconic cusps.
|
| 27. | Their gyroradius shrinks and when they hit a dense magnetic field they can be reflected using the magnetic mirror effect.
|
| 28. | The properties of magnetic mirrors can be derived using the adiabatic invariance of magnetic flux under changes in magnetic field strength.
|
| 29. | This arrangement solved one of the main problems with the basic magnetic mirror concept, which had open field lines at the ends.
|
| 30. | The magnetic mirror was first published in 1967 by Richard F . Post and many others at the Lawrence Livermore National Laboratory.
