An e-beam-driven coherent radiation source operating at high cyclotron harmonic is designed. This device, called 'inverted cusptron', has a coaxial line configuration structured with both slotted central line and outer conductor. It used a cusp-magnetic field to convert a hollow e-beam produced from an annular thermoionic cathode into an e-layer as the radiation source. As an advantageous feature, the central cylindrical tube of the structure can be used as input-output ports for an amplifier setup. A particle simulation code is developed to study the intersection between the electrons in the e-layer and the mode fields of the tube.
