We have developed a simple method to measure the phase space of ion beams by using standard beam line components like moveable slits and a beam profile monitor [1].
We now present an automated phase space measurement device. The entire measurement procedure is performed by an embedded controller. The operating system of the controller (DIL/NetPC) is based on Linux with a real time extension. It controls the movement of the slits and records the data synchronized to the movement of the beam profile monitor. For every position of the slits (spacing 0.05 mm), a beam profile is acquired. The data are sent via TCP/IP to the data acquisition system of VERA, where visualization takes place. Presently, a hardware prototype is fully functional, also the visualisation software works succesfully.
One phase space measurement (either x or y) will take less than 10 seconds, which will allow to use the device for routine beam tuning. The design and the characteristic of the device will be discussed.
