Abstract :
A Smith-Purcell radiation source using a grating structure modified in a cylindrical manner was considered to utilize a high power relativistic annular electron beam. The output characteristics were confirmed by numerical simulations assuming a 500 keV-5 kA electron beam. The experiment is being prepared.
