The guard is ideally an extension of the cylindrical probe, having the same voltage as the probe, but being electrically
WebThe probe consists of a collector, a guard, and a sleeve electrode. Besides being easier to construct, this modified probe geometry is more amenable to numerical verification of its operating properties. Such a verification is carried out by numerically following selected collisionless orbits of charged particles in the electric field of the probe.
