Abstract : Under the support of this equipment grant, the facilities of the Plasma laboratory of the Institute used for an on-going research program funded by the AFOSR have been upgraded. Our research program bears the scientific goal to develop a high power, compact microwave device carrying good output efficiency. A cusptron device is thus designed to fir the requirements, This device utilizes the negative mass instability for the resonant interaction between an axis-encircling electron beam and the modes of a slotted cylindrical waveguide. This beam configuration is prodiced by passing an electron beam through cusp magnetic field and maximizes the finite Larmour radius effect for harmonic cyclotron resonance interaction. Further, the slotted boundary introducing a periodic fringe field near the orbits of the electron beam, thus, enriches the resonant harmonic contents of the rf fields as experienced by the gyrating electrons.
