Sheet electron beams have the potential to make possible higher power sources of coherent millimeter-wave radiation. Recent studies indicate the feasibility of stable focusing of low-emittance sheet beams using periodically-cusped magnetic (PCM) fields. The authors will discuss progress on the preparation of experiments to study the stability and transport of PCM-focused sheet electron beams. This includes a laboratory method to form sheet beams using magnetic quadrupole lenses, a commercially relevant strip-beam thermionic electron gun design, and a PCM configuration to confine the beam in both transverse dimensions. The experiments will involve a 10 kV, 2 A, 1.6 mm X 36 mm elliptical sheet beam and a PCM array with a 3.5 cm spatial period. Peak midplane magnetic fields of 1.0 kG should be adequate for stable beam focusing. The experimental studies will be complemented by numerical simulations using the MAGIC particle-in-cell code and the TOSCA 3-D magnetic design code.
