This workshop is jointly organized by the QUASAR and THz-Groups and covers the R&D work of both groups in Accelerator Science and Technology. During the five-day workshop, the participants will work on the following topics: > Beam Instrumentation for Present and Duture Particle Accelerators; > Challenges from Vacuum Technology; > Accelerator Beam Dynamics; > Ion beam-based Cancer Therapy; > Disentanglement in Data Analysis. The workshop also contains a careers session that is targeted at researchers at the early stage of their careers, i.e. M.Sc./Ph.D. students and young Postdocs and shall help facilitating their next career steps.
