Active High-Power RF Pulse Compression Using Optically 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...

Rf Pulse Compression via Te01 Optically Controlled Multi- Megawatt Microwave Switch

We present the design and experimental results of an optically controlled high power pulse compression system. The rf parameters of the system are chosen to fit the requirements of the X-band Next Linear Collider design at SLAC. The system is based on the switched resonant delay line theory [1]. The high power microwave switch, required for this system, is realized using optical excitation of a...

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,...

High-power Rf Pulse Compression W Ith Sled-ii at Slac*

Increasing the peak rf power available from X-band microwave tubes by means of rf pulse compression is envisioned as a way of achieving the few-hundred-megawatt power levels needed to drive a next-generation linear collider with 50-100 M W klystrons. SLED-II is a method of pulse compression similar in principal to the SLED method currently in use on the SLC and the LEP injector linac. It utiliz...
