Titanium pump working principle

The motion of the electron in the titanium pump anode tube in axial velocity component, Vz and radial velocity Vr, because Vr and axial magnetic field Bz perpendicular, electron by the Lorentz force F=eVr´ Bz effect, so the electrons to the anode tube in addition to the action of electric field force is axial symmetry, but also by the Lorentz force Bz, the electron motion into linear motion and axial cross section on thewheel rolling line movement. 

   In cross section of electricity Sub wheel rolling line moving radius size is a function of the electron velocity and magnetic fieldstrength, the larger the electronic speed (the anode voltage is higher), round the ring rolling line larger; magnetic field stronger, wheel rolling line of the circle is smaller.
