Since a lower E c means a higher voltage (see Section 2.4), the N side is at a higher voltage or electrical potential than the P side. Download PDF. Physics > Instrumentation and Detectors. Both of these features depend strongly on the amount of space charge in the TPC gas volume, mainly due to the ions from the amplification stage. collisions.

Space-charge-limited current is considered in a thin-film n-i-n diode. It is assumed that impenetrable barriers limit the current flow to a film of thickness D . The properties of two types of space-charge flow crossed-field electron guns are investigated. The first type is a form of short gun; the second one is a type of long gun in which the electron stream is accelerated adiabatically. Both guns are intended for use in M-type injected beam microwave devices in which, ideally, electron beams satisfy of current flow should have no influence on the amount of recombination which takes place. It is shown below, however, that field asymmetry due to space charge may still affect the region from which ions can reach collecting electrode, and thus lead to a change in current when the polarity of the collector is reversed. 5 3.
The equations of electrostatic irrotational space‐charge flow are set up in a paraxial manner. Given an arbitrary trajectory, and the potential distribution along that trajectory, the variation of such quantities as potential and beam convergence in the vicinity of the specified trajectory are investigated. We have designed a high current electrostatic scanner-deflector. The scanner includes electron gates to confine the space-charge-unneutralized region to the immediate vicinity of the scanner. The remaining beam divergence due to space charge has been compensated for by the inherent focusing property of the scanner. Since this latter effect Abstract. During the past three years we have had occasion to design and build magnetron-injection guns for producing hollow beams. These guns have been designed both from a planar space-charge flow which has been described by Kino and Taylor [1] and more recently from one of the axially-symmetric flows described by Kirstein [2]. Abstract. In some papers concerned with the exact solution of the equations of a nonrelativistic single-energy beam of charged particles (e.g., [1, 2]), the opinion has been expressed that, while the method of separation of the variables has possibilities, serious difficulties can arise in obtaining the actual systems with separated variables.

S. Kino, and W. E The equations for irrotational, electrostatic laminar space‐charge flow (no thermal velocities or normal magnetic field at the cathode) are set up in terms of the action function. The resulting nonlinear partial differential equation is first reduced, by the method of the separation of variables in cylindrical polar coordinates, to the solution of a set of first‐order, nonlinear, ordinary
