The stability of the hot-electron precessional mode is investigated in the presence of a relative Earrow x Barrow precession between the end cell and the center cell, which is inherent to the tandem-mirror concept. It is found that a positive radial electric field in the end cell is favorable to stability. Under normal conditions, the stability of a hot-electron symmetric tandem mirror is not worse than a quadrupole tandem mirror with the same relative Earrow x Barrow precession.
