Transverse Beam Position Pick-up for SPS

The image shows the vacuum chamber and the pick-up electrodes for a transverse beam position monitor of the SPS. The block with the electrodes slides into the vacuum chamber when the pick-up is assembled. The two feedthrough parts provide a vacuum tight signal link from the electrodes through the vacuum chamber to the outside world. The external end of the feedthrough allows the connection of a coaxial cable leading to the signal processing electronics.
