Non-Electrostatic Diagnostics for Ion Beams

Abstract

The article reports on non-electrostatic diagnostics for ion beams. A novel galvanometric force measuring probe is presented, and results are compared with corresponding measurements by a calorimetric technique and using falling microparticles. The target chamber is operated at argon pressures where charge-exchange collisions are important. It is highlighted that non-electrostatic methods are sensitive for ions as well as energetic neutral atoms. For the first time, bombardment induced light emission (BLE) from solid targets is proposed as simple beam diagnostic. © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
