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...

The perovskite structure materials have been used widely in a lot of fields of the modern technology. They are used as high density capacitors, actuators, pyroelectric detectors and piezoelectric transducers [1]. The PFN – Pb(Fe0.5Nb0.5)O3 ceramics also belongs to the group of perovskite type materials, in which ions Fe3+ and Nb5+ are arranged in the octahedral positions at random [2]. This fer...

Design Optimization and Construction of the Thyratron/pfn Based Cost Model Modulator for the Nlc*

As design studies and various R&D efforts continue on Next Linear Collider (NLC) systems, much R&D work is being done on X-Band klystron development, and development of pulse modulators to drive these X-Band klystrons. A workshop on this subject was held at SLAC in June of 1998, and a follow-up workshop is scheduled at SLAC June 23-25, 1999. At the 1998 workshop, several avenues of R&D were pro...
