Available in PDF, EPUB and Kindle. Book excerpt: The peak power delivered by the klystrons in the NLCRA (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, however, will require even higher peak power and larger compression factors, which favors a more efficient binary pulse compression approach. Binary pulse compression, however, requires a line whose delay time is approximately proportional to the compression factor. To reduce the length of these lines to manageable proportions, periodically loaded delay lines are being analyzed using a generalized scattering matrix approach. One issue under study is the possibility of propagating two TE{sub o} modes, one with a high group velocity and one with a group velocity of the order 0.05c, for use in a single-line binary pulse compression system. Particular attention is paid to time domain pulse degradation and to Ohmic losses.

This book was released on 2005 with total page 1 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pulse compression systems for future linear colliders, such as NLC and JLC, involve hundreds of kilometers of waveguide runs. These waveguides are highly overmoded to reduce the rf losses. Reducing the length of these waveguide by loading them with irises increase the losses of the system. Also, loading makes the waveguide depressive, and rf pulse shapes get distorted. In this paper we present a novel idea for utilizing the waveguides several times by using different modes. All the modes being used have low-loss characteristics. We describe mechanically simple mode transducers that switch the propagation mode from one configuration to another with no observable dispersion. We compare our theoretical designs with experimental data.

Available in PDF, EPUB and Kindle. Book excerpt: Dispersive delay lines are a very stable and reliable pulse compression technique. As a result of increased requirements placed on pulse compression systems such as bandwidth, and time-bandwidth products, dispersive delay line techniques must be improved. Improved dispersive delay line technology as applied to pulse compression systems was investigated. Higher frequency of operation, broader bandwidth and greater ease of fabrication were the primary areas of interest. Two dispersive delay line configurations were investigated. The first configuration was a technique based on the dispersive characteristic which results from elastic waves propagating in thin metal strips, and the second configuration was based on slow wave propagation in a yttrium iron garnet. An investigation was undertaken to determine a highly efficient transducer to be used in conjunction with the dispersive delay lines. Vacuum deposited cadmium sulfide transducers proved to be most desirable and successful in constructing delay lines of broad instantaneous bandwidth. (Author).

Book Synopsis Delay Line Investigation by : David E. Flinchbaugh
Download or read book Delay Line Investigation written by David E. Flinchbaugh and published by . This book was released on 1969 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: A dispersive delay line of the perpendicular diffraction grating type was investigated. The delay line operated at 100 MHz with 40 MHz bandwith and 26.7 microsecond dispersion. One of the program's primary goals was insertion loss reduction. To this end a technique was developed that reduced the insertion loss from 95 db (best previously obtained) to 60 db. A breadboard pulse compression system was fabricated and demonstrated using the delay line. The system exhibited over 1000:1 pulse compression ratio, 35 ns compressed pulse width at the -3 db points, -33.5 db sidelobe level, and 55 db dynamic range. The system is lightweight, compact, and well suited to airborne applications. It is highly probable that the technique is applicable to pulse compression ratios approaching 10000:1. (Author).
