A Method for Measuring the r.m.s Beam Dimension σx2 − σy2 — •Joel Alain Tsemo Kamga, Wolfgang F. O. Müller, and Thomas Weiland — Institut für Theorie Elektromagnetischer Felder, 64289 Darmstadt, Germany
Quadrupole pickups are of particular importance in the accelerator physics because they allow the measurement of some parameters like the beam emittance. However, the emittance can be obtained by measuring the quadrupole moment of the beam by means of a quadrupole pickup consisting of four electrodes placed at 0∘ (Right), 90∘ (Top), 180∘ (Left) and 270∘ (Bottom). Usually, the difference over sum method is used to pick up the quadrupole moment. However, we use another method starting from the log-ratio method. The analysis and comparing of all these methods will be presented in this work.
