A Pulse to Pulse Klystron Diagnosis System

Pulse Transformer R&d for Nlc Klystron Pulse Modulator

We have studied a conventional pulse transformer for the NLC klystron pulse modulator. The transformer has been analyzed using a simplified lumped circuit model. It is found that a fast rise time requires low leakage inductance and low distributed capacitance and can be realized by reducing the number of secondary turns, but it produces larger pulse droop and requires a larger core size. After ...

Development of the Pulse Transformer for Nlc Klystron Pulse Modulator

We have studied a conventional pulse transformer for the NLC klystron pulse modulator. The transformer has been analyzed using a simplified lumped circuit model. It is found that a fast rise time requires low leakage inductance and low distributed capacitance and can be realized by reducing the number of secondary turns, but it produces larger pulse droop and core size. After making a tradeoff ...

Two-Klystron Binary Pulse Compression at SLAC*

The Binary Pulse Compression system installed at SLAC was tested using two klystrons, one with 10 MW and the other with 34 MW output. By compressing 56@ ns klystron pulses into 70 ns, the measured BPC output wss 175 MW, limited by the available power from the two klystrons. This output was used to provide 10GMW input to a 36cell X-band structure in which a lOO-MV/m gradient was obtained. This s...

Design of a Pfn for the Nlc Klystron Pulse Modulator

A pulse-forming network(PFN) with mutual coupling has been designed and built for the klystron pulse modulator of the SLAC Next Linear Collider(NLC). The PFN consists of a single-layer air-core coil with mutual coupling between sections and equal valued capacitors. The optimization of the coupling coefficient and the design of the air-core coil such as its radius, the number of turns and its to...
