Microwave Cold-Testing Techniques for the NLC
نویسندگان
چکیده
The R & D program for the Next Linear Collider Test Accelerator (NLCTA) includes the development of microwave techniques for testing Xband accelerating structures at different stages of design, manufacturing and assembly. During the design phase, short stacks were built and tested to finalize dimensions. Cell by cell measurements were performed on the NLCTA injector cells as a microwave quality control (QC) after manufacturing. The two injector sections were tuned using a moveable plunger and tested using a semiautomated system of bead-pull. Using this perturbation technique, we were able to map the amplitude and phase of the electric field on the axis throughout the assembled structures under traveling-wave conditions.

Microwave Quadrupoles for Beam Break-up Supression In the NLC Main Linac
This is a preliminary study of the effect of using microwave quads (MQs) instead of rf phase shifting to induce BNS damping in the main linac of the NLC collider. We consider MQs running at X-band, and find that the total length of MQs needed for the NLC is 6% of the total length of the accelerating structures. We show through simulations that, by using MQs instead of phase shifting for BNS dam...

The very first klystron in the XC series, (XCl), The SLAC design for a l-TeV collider (NLC) requires klystrons with a performance which is well beyond the state-of-the-art for microwave tubes in the United States or abroad. The electrical specifications for the NLC klystrons are not fully established, but they are approximately as follows: Frequency: Peak Power:

The Wittig reaction rate can be dramatically enhanced by irradiation of the reaction mixture containing an aldehyde or ketone; methoxymethyl(triphenyl)phosphonium chloride, potassium t-butoxide, and t BuOH with a commercial microwave oven. Carbonyl compound are converted to Witting products within three min. in good yields.
متن کاملHigh Power Rf Component Testing for the Nlc
In the Next Linear Collider (NLC), the high power rf components must be capable of handling peak rf power levels in excess of 600 MW. In the current view of the NLC, even the rectangular waveguide components must transmit at least 300 MW rf power. At this power level, peak rf fields can greatly exceed 100 MV/m. We present recent results of high power tests performed at the Accelerator Structure...
