Smith-Purcell radiation (SPR), emitted when a charge passes above a periodic grating, is important for applications such as terahertz production and nondestructive bunch-length diagnostics. The grating width is shown to become an important parameter

We report the absolute power measurement of frequency-locked terahertz coherent transition radiation (CTR) from a train of electron bunches produced by a 17.14 GHz accelerator. Frequency measurements were obtained by two independent techniques: a wav

Frequency-locked Smith-Purcell radiation (FL-SPR), generated by a train of electron bunches traveling above a grating, is characterized by a broad range of frequencies which are locked to the train frequency in a discrete comb and are spatially dispe

Smith-Purcell radiation (SPR), generated by an electron beam traveling above a grating, is characterized by a broad range of frequencies. The radiated wavelength depends on the angle of observation according to the SPR resonance relationship and the

The use of drift-step-recovery diodes (DSRDs) for producing high-voltage pulses in the nanosecond range requires a prime switch. The prime switch pumps the DSRD with carriers in the forward direction and then pulses the DSRD quickly in the reverse di

Drift-step-recovery diodes (DSRDs) are fast-opening switches capable of delivering nanosecond-scale high-voltage (HV) pulses into a load. The HV capability is achieved by stacking DSRD dies in series. In this paper, we characterize a DSRD die based o

A silicon-avalanche shaper/sharpener is a fast-closing semiconductor switch. For positive voltages, it is activated by a high-voltage pulse at its cathode, and, when turned on, the current through the device rises rapidly. Using Synopsys TCAD softwar

Drift-step-recovery diodes (DSRDs) are used in pulsed-power generators to produce nanosecond-scale pulses with a rise rate of the order of 1 kV/ns. A 2.2 kV, 1 ns pulsed power circuit is presented. The circuit features a single prime switch that util
