At the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany, a prototype cryomodule (Advanced Demonstrator) for the superconducting (SC) continuous wave (CW) Helmholtz Linear Accelerator (HELIAC) is under construction. A transport line, comprising quadrupole lenses, rebuncher cavities, beam correctors and sufficient beam instrumentation has been built to deliver the beam from the GSI 1.4 MeV/u High Charge Injector (HLI) to the Advanced Demonstrator, which offers a test environment for SC CW multigap cavities. In order to achieve proper phase space matching, the beam from the HLI must be characterized in detail. In a dedicated machine experiment the bunch shape has been measured with a non destructive bunch shape monitor (BSM). The BSM offers a sufficient spatial resolution to use it for reconstruction of the energy spread. Therefore, different bunch projections were obtained by altering the voltage of two rebunchers. These measurements were combined with dedicated beam dynamics simulations using the particle tracking code Dynamion. The longitudinal bunch shape and density distribution at the beginning of the matching line could be fully characterized.

The Institute for Applied Physics (IAP) of Goethe University Frankfurt has a long history in developing DTL-cavities and further essential components of particle accelerators from design and simulation up to tuning and final testing. In recent times, the development of beam diagnostic components for the hadron accelerator projects has become increasingly important. Bevatech is designing and setting up linear accelerators, RF and vacuum technology for research laboratories and enterprises worldwide. In a joint effort a simple, efficient and mobile beam position monitor (BPM) test bench has been developed and will be further improved for future tests and the calibration of beam position monitors. It is fully automated using single-board computers and microcontrollers to obtain the essential calibration data like electrical offset, button sensitivity and the 2D response map. In addition, initial tests with the implementation and evaluation of the Libera signal processing units Single Pass H and Spark were promising.
