WebNow, in order to accelerate ions to the Bohm velocity, the potential drop across the pre-sheath needs to be , where is the electric potential in the interior of the plasma. It follows from Equation ( 4.260 ) that the relationship between the electron number density at the sheath boundary, , and the number density in the interior of the plasma, , is Web, called the Bohm velocity, or the ambipolar speed of sound. This is the velocity at which ions enter the plasma sheath after falling through a small, but not-negligible potential drop in the pre-sheath. Notice that this peculiar velocity … simon school two thousand sixteenWebalso showed that the Bohm criterion is the right choice for the sheath boundary only if where is the ion mean free path in presheath region. For collisional plasmas, the deﬁnition of the sheath bound-ary is ambiguous [5], [21]–[23]. When is is small according to Riemann [5], the Bohm criterion is still good for the sheath boundary. simon school mba
