Coatings for the Aps Rf Cavity Tuners for the Reduction of Secondary Electrons *
نویسندگان
چکیده
Thin film coatings are used to reduce the generation of secondary electrons at the ends of the Advanced Photon Source (APS) rf cavity tuners because these electrons result in increased temperatures on the tuner. To improve the film properties over the existing evaporated titanium film, a magnetron-sputtered film of titanium nitride has been developed that is both harder and adheres more strongly than the past evaporated film. This paper describes the process for creating this new coating.

Secondary Electron Yield of a Thin Film Coating on the Aps Rf Cavity Tuners
A thin film coating of titanium nitride was applied to the surface of rf cavity tuners to reduce secondary electron generated when the existing copper base material is in place. The tuners are used in high-field gradients, where electron heating of the tuner is a problem. By reducing the generation of electrons the temperature of the tuners will be reduced, for better reliability. This paper co...
متن کاملStatus of Rf Deflecting Cavity Design for the Generation of Short X-ray Pulses in the Advanced Photon Source Storage Ring
The Advanced Photon Source (APS) at Argonne National Laboratory is exploring the possibility of using radio frequency deflection to generate x-ray radiation pulses on the order of 1 pico-second (Delta t – 70%) or less [1]. This scheme is based on a proposal by A. Zholents et al. [2] that relies on manipulating the transverse momentum of the electrons in a bunch by using an rf deflecting cavity ...
متن کاملEvaluation of changes in excision cavity volume during whole breast irradiation using secondary CT image
Background: The aim of this study was to evaluate the reduction in excision cavity volume (ECV) during the whole breast radiotherapy (WBRT). The delineating of reduced cavity volume on secondary CT (computed tomography) might decrease the field size of boost plan. Materials and Methods: Twenty patients were treated having breast conservative surgery. At first, primary CT simulation (CT-1) was d...

The absorption performance of anechoic coatings depends on the material properties, layer thicknesses and cavity distribution density and cavity size. In this paper a design method based on numerical simulation was presented by combining FEM and acoustic duct method (ADM). Analyzing of anechoic coatings was performed under active sonar impinging plane wave by normal incident angle. In thi...
متن کاملEvaluation of the Effects of Different Filters and Helium Bag on the Reduction of Electron Contamination in Photon Beam of Neptun Linac
Introduction: Skin sparing is one of the most desirable characteristics of high energy photon beams. However, the photons emerging from the target of linacs are contaminated by secondary electrons as a result of their interactions with air, collimators, flattening filter and any other objects in their path. This phenomenon tends to increase the skin dose received b...
