Analysis of Real Materials for the RF Window of a GHz Transition Radiation Monitor — •Stephan Klaproth1,2, Herbert De Gersem2, and Andreas Penirschke1 — 1Technische Hochschule Mittelhessen, Friedberg, Hessen — 2TU Darmstadt, Darmstadt, Hessen
State of the art measurement devices for longitudinal beam profiles typically include Feschenko monitors, Fast Faraday Cups, and field monitors. A novel approach of a GHz diffraction radiation monitor is able to non-destructively measure the longitudinal charge distribution of each micro-bunch within a bunch-train of a heavy ion beam. In this contribution, we compare several vacuum-grade, dielectric materials for the monitor’s rf window aiming at signals as strong and well distinguishable as possible with beam energies of β = 0.05 to 0.75. To achieve this, numerical field simulations were performed with CST Particle Studio® to investigate the influence of different window materials on the signal strength.
