title: In-line ion detector.
abstract: An in-line particle detector (IPD) uses secondary electrons for the detection of multiply charged ions with low to medium energy (10-10 keV). The ion detector does not physically intercept the ion beam line and is fully transparent to ions without applied voltages. The activation of the detector is performed by applying appropriate voltages to electrodes, which avoids any physical movement. Equipped with a channel electron multiplier, single particle counting is possible as well as measurement of currents. This detector therefore has a large dynamical range from about 10(-17) to 10(-3) A. The basic principle also allows for ion beam diagnostics.
