abstract = {{The Heidelberg Ion Beam Therapy Centre (HIT) is a synchrotron based medical accelerator facility for the treatment of cancer patients with ions. Since the first treatment in November 2009 about 7000 patients have been irradiated with protons or carbon ions and, since July 2021, also with helium ions. In 2010 HIT started the operation of a test bench with a setup comparable to the LEBT at the accelerator. Since 2013 the test bench serves as a common low energy beamline of Siemens Healthcare and HIT with components from both partners. In parallel to ion source and RFQ research and development we have experimented with our proprietary pepper pot device. We plan to install the final version of the pepper pot into the LEBT section and use the measured beam distributions for the design of a new RFQ. With the recent redesign of the mask-target assembly we have increased the active area of the device and generated a possibility for an accurate pixel calibration by a specialised calibration mask. Our tool PePE (Pepper Pot Emittance Evaluation) offers different approaches for the reconstruction of the 4D emittance parameters from the raw image. The evaluation process was validated by a pepper pot image generated from a simulated beam with known properties.}},
