TI - A Multi-pinhole Faraday Cup Device for Measurement of Discrete Charge Distribution of Heavy and Light Ions J2 - Proc. of IPAC2015, Richmond, VA, USA, May 3-8, 2015 C1 - Richmond, VA, USA T2 - International Particle Accelerator Conference T3 - 6 LA - english AB - It is a difficult task to identify the beam density distribution profile over discrete areas using a standard Faraday cup, as the measurements are provided for the full aperture geometry of the instrument. Ideally, the intensity of the scintillating material would provide a correlation to the beam density, but the low photon efficiency, damage to the scintillator, and camera resolution all limit the practicality of using this system for assessing the spatial resolution of an ion beam. A beam profile monitor (BPM) device has the ability to provide a partial or discrete distribution of an integrated beam profile. The BPM, however, does not discriminate between ions and electrons, the latter of which can be problematic for assessing the full beam profile. To provide a better description of the beam density in spatial dimensions, a multi-pinhole Faraday cup (MPFC) has been designed, developed, and applied to the measurement of energetic ions. This device uses an array of millimeter sized Faraday cups arranged in a grid to measure the current of the beam at discrete locations. This report presents the design of the device, and its performance with ion beams.
