The Generation of 400-MW RF Pulses at -Band Using Resonant Delay Lines
نویسندگان
چکیده
In this paper, we present theory and experimental data for a resonant-delay-line pulse-compression system. The system is fed by two high-power klystrons at X-band. The peak output power is four times the input power. The system produces flat-top output pulses. It uses evacuated room-temperature copper delay lines as a means of storing energy. These lines achieved a quality factor greater than 4.3 105, with total losses due to external components measured at 4%. We compare theory with experimental results. The system produced 150-ns pulses at power levels around 470 MW.

Binary Rf Pulse Compression Experiment at Slac
Using rf pulse compression it will be possible to boost the 50to lOO-MW output expected from high-power microwave tubes operating in the loto 20-GHz frequency range, to the 300to lOOO-MW level required by the next generation of high-gradient linacs for linear colliders. A high-power X-band three-stage binary rf pulse compressor has been implemented and operated at the S&ford Linear Accelerator ...
متن کاملBright broadband coherent fiber sources emitting strongly blue-shifted resonant dispersive wave pulses.
We predict and realize the targeted wavelength conversion from the 1550-nm band of a fs Er:fiber laser to an isolated band inside 370-850 nm, corresponding to a blue-shift of 700-1180 nm. The conversion utilizes resonant dispersive wave generation in widely available optical fibers with good efficiency (~7%). The converted band has a large pulse energy (~1 nJ), high spectral brightness (~1 mW/n...
متن کاملResults of an RF Pulsed Heating Experiment at SLAC
Results are reported from an experiment on RF pulsed heating of copper at SLAC. Damage in the form of cracks may be induced on the surface after the application of many pulses of RF. The experiment consists of two circularly cylindrical cavities operated in the TE011 mode at a resonant frequency of 11.424 GHz. Each cavity received 8.5 MW, 1.2 μs pulses at 60 Hz corresponding to a calculated tem...

SLAC is committed to developing an X-band source _ capable of producing 100~MW, I-ps pulses to power the next linear collider [3]. The fust experience encountered at -, -SEAC in the X-band regime above a few megawatts was in the relativistic klystron program in cooperation with LLNL and LBL [2]. About 280 MW had been transmitted through a variety of waveguide components but at very short pulse ...
متن کاملSeeded free-electron and inverse free-electron laser techniques for radiation amplification and electron microbunching in the terahertz range
A comprehensive analysis is presented that describes amplification of a seed THz pulse in a single-pass free-electron laser (FEL) driven by a photoinjector. The dynamics of the radiation pulse and the modulated electron beam are modeled using the time-dependent FEL code, GENESIS 1.3. A 10-ps (FWHM) electron beam with a peak current of 50–100 A allows amplification of a 1 kW seed pulse in the fr...
