Abstract:
A compact apparatus for the production of intense THz radiation comprising;a) a particle beam source that generates a short bunch particle beam having an energy between about 100 and about 500 KeV, a charge of between about 1 and about 10 pico coulombs, a repetition rate of from about 500 to about 3000 MHz at a current of less than about 30 milliamps and an emittance of <20 mm mrad, b) a linac comprising one or a series of compact superconducting cavities that are capable of delivering up to about 10 million volts that accelerates said beam as it is received from said particle beam source; c) a wiggler/undulator that receives said beam from said linac and exhibits the following properties: &ggr;w of about 3 cm, Np of about 50 and a field K of about 1 Tesla; and d) a magnet that bends said particle beam as it exits said wiggler/undulator thereby permitting extraction of THz radiation therefrom.
