Active radio frequency pulse compression using switched resonant delay lines

Active Radio Frequency Pulse Compression Using Switched Resonant D.elay Lines*

This paper presents a study and design methodology for enhancing the efficiency of the SLED II rf pulse-compression system [l]. This system employs resonant delay lines as a means of storing rf energy. By making the external quality factor of these lines vary as a function of time, the intrinsic efficiency of the system can reach 100%. However, we demonstrate a considerable increase in efficien...

Active High-Power RF Pulse Compression Using Optically Switched Resonant Delay Lines

Radio Frequency Pulse Compression*

High gradients require high peak powers. One possible way to generate high peak powers is to generate a relatively long pulse at a relatively low power and compress it into a shorter pulse with higher peak power. It is possible to compress before DC to RF conversion as is done for the relativistic klystron or after DC to RF conversion as is done with SLED. In this note only radio frequency puls...

Loaded Delay Lines for Future R.f. Pulse Compression Systems

The peak power delivered by the klystrons in the NLCTA (Next Linear Collider Test Accelerator) now under construction at SLAC is enhanced by a factor of four in a SLED-II type of R.F. pulse compression system (pulse width compression ratio of six). To achieve the desired output pulse duration of 250 ns, a delay line constructed from a 36 m length of circular waveguide is used. Future colliders,...
