      abstract     = {The transformer ratio, the ratio between maximum
                      accelerating field and maximum decelerating field in the
                      driving bunch of a plasma wakefield accelerator (PWFA), is
                      one of the key aspects of this acceleration scheme. It not
                      only defines the maximum possible energy gain of the PWFA
                      but it is also connected to the maximum percentage of energy
                      that can be extracted from the driver, which is a limiting
                      factor for the efficiency of the accelerator. Since in
                      linear wakefield theory a transformer ratio of 2 cannot be
                      exceeded with symmetrical drive bunches, any ratio above 2
                      is considered high. After the first demonstration of high
                      transformer ratio acceleration in a plasma wakefield at
                      PITZ, the photoinjector test facility at DESY, Zeuthen site,
                      limiting aspects of the transformer ratio are under
                      investigation. This includes e.g. the occurrence of bunch
                      instabilities, like the transverse two stream instability,
                      or deviations of the experimentally achieved bunch shapes
                      from the ideal.},
