Stripline electrodes collect electrons that would otherwise impact the beam-pipe surface. The striplines are placed behind an array of small holes in the beam-pipe wall in order to shield them from the beam-induced electromagnetic pulse. There are three striplines placed near one of the pole tips so that they cover a roughly 0.43 radian azimuth. The beam-pipe chamber has also been designed so that microwave measurements of the electron cloud density can be performed. Beam position monitor buttons have been included for excitation and reception of microwaves and the chamber has been designed so that the resonant microwaves are confined to be within the 56 cm length of the quadrupole field. This paper provides some details of the design including CST Microwave Studio time domain simulation of the stripline detectors and eigenmode simulation of the resonant chamber. The detector is installed in the Cornell Electron Storage Ring and is part of the test accelerator program for the study of electron cloud using electron and positron beams from 2 to 5 GeV.
