      abstract     = {In January 2021 two X-band (12 GHz) PolariX Transverse
                      Deflecting Structures with variable streak polarization were
                      installed into the FLASH2 beamline at FLASH. Since none of
                      the RF components for the FLASH2-PolariX RF-distribution
                      system nor the two PolariX structures could be
                      pre-conditioned, RF-conditioning was and is quite tedious.
                      Nevertheless, after 6 weeks of conditioning, we have already
                      been able to streak the electron beam enough to start
                      commissioning of the PolariX controls and the software.
                      After 4 months of conditioning in parallel to FLASH2 user
                      operation, we achieved a stable 5.5 MW flat top of 400 ns
                      operation. Next step will be to include RF pulse compression
                      to achieve the design power of 22 MW. Since then operational
                      experience with the PolariX system has continuously evolved
                      and it has quickly become a valuable if not indispensable
                      tool for tuning FLASH2. Even with the reduced power, a
                      measurement resolution of 12 fs could be reached. In this
                      article we describe key aspects of the conditioning and
                      commissioning process as well as the first experiences and
                      first results of beam measurements both for SASE tuning and
                      for dedicated micro-bunching studies.},
