Abstract

The Laboratory of Nuclear Studies is proposing an upgrade to the existing CESR electron-positron storage ring to make possible the study of CP violation of B meson decays. This B-Factory, because of the required luminosity and the resultant high beam current, will require very high RF power levels to replace the synchrotron radiation and the HOM (higher order mode) energy losses of the beams. The proposed design would require 16 superconducting cavity structures, each with an RF input power of approximately 400 kW at 500 MHz. The design requirements and the feasibility of a planar waveguide vacuum window are considered. Low-power and high-power measurements are described. The test results are provided.<>
