Abstract
A study is made of the imaging properties of an electrostatic quadrupole that has been uniformly twisted about its axis. It is shown that the structure is capable of identically reproducing the injection coordinates and momenta of a system of particles in a coordinate plane which is located some distance along the quadrupole. The imaging takes place with a small amount of aberration. This aberration can be greatly reduced by constructing the lens of two sections which follow each other and which have equal and opposite twists.
