Abstract
A ''radius-tailored'' electron beam, which is tapered with a larger he ad and a smaller tail, has been generated. This has been accomplished by injecting the electron beam into a fast rise-time magnetic focusing coil, so that the beam head expands while the beam body and tail are confined by the axial magnetic field. Time-resolved beam radius measur ements indicate that a beam radius tailoring on the order of 3 to 1 ha s been achieved. This result is also in agreement with computer simula tions.
