Experimental study of rf pulsed heating
WebAn experiment to study the effects of RF pulsed heating on copper has been developed at SLAC. The experiment consists of two circularly cylindrical cavities operating in the TE/sub 011/ mode at a resonant frequency of 11.424 GHz. These cavities are connected by a magic tee and driven by a 50 MW X-band klystron. Each cavity receives an input pulse of 20 … WebThe measurement of the pulsed temperature rise will be performed as follows. Before the application of a high-power RF pulse, the TE 012 mode will be set up in steady state …

This is especially true for structures that have complicated features for wakefield damping. WebCyclic thermal stresses produced by rf pulsed heating can be the limiting factor on the attainable reliable gradients for room temperature linear accelerators. This is especially true for structures that have complicated features for wakefield damping. These limits could be pushed higher by using special types of copper, copper alloys, or other conducting …
WebThe diagnostic consists of simultaneously exciting a TE 012 mode to steady-state in the cavity at 18 GHz and measuring the change in reflected power as the cavity is heated from high-power pulsed RF. Two experimental runs were completed. One run was executed at a calculated temperature rise of 120 K for 56 × 10 6 pulses.
