      abstract     = {The FLASH 2020+ project at DESY includes, among other
                      modernizations, an increase of the electron beam energy. Two
                      accelerator modules were replaced and the RF distribution of
                      other modules was optimized. The limiting factors such as
                      cavity breakdown and field emission were identified and
                      measured through dedicated studies. At a later stage, based
                      on these measurements, adjustments to the high-power
                      distribution were proposed and the optimal operating point
                      was demonstrated to achieve the design electron energy of
                      1.35 GeV with the nominal RF pulse length at FEL lasing
                      conditions. After proper optimization and tuning of the
                      low-level RF parameters, the linac successfully operated at
                      maximum energy and delivered FEL radiation in the wavelength
                      range below 3.2 nm. The measurement results as well as the
                      achieved cavity gradients with energy gains are presented.},
