Abstract

Following the method of Sands and Rees, we have developed a two arm comparison apparatus of high sensitivity and good temporal resolution for the measurement of bunch engendered fields. With a relative timing uncertainty of .5 picoseconds the apparatus has demonstrated a sensitivity of .05Ω for the resistive impedance in the presence of a reactive impedance of 4.2Ω for a gaussian shaped bunch of standard deviation 2.1 centimeters. The apparatus is described and results for a typical component are presented. Both energy loss and bunch generated fields are discussed.
