A Beam Position Monitor System for Electron Cooler in HIRFL-CSR

    Graphical Abstract
    • Abstract
  • The efficient electron cooling requires that the ion beam and electron beam are parallel and overlapped. In order to measure the positions of ion beam and electron beam simultaneously， a beam position monitor system is developed for the HIRFL-CSR electron cooler device， which probe consists of four capacitive cylinder linearcut poles. One can get the both beam positions from the picking up signals of four poles by using Fourier transform(FFT) method. The measurement results show that the beam position monitor system is accurate. This system is suitable for investigating the relation between electron cooling processing and the angle of ion beam and electron beam.
