Abstract: In January 2021 two X-band (12GHz) PolariX Transverse De- flecting Structures with variable streak polarization were installed into the FLASH2 beamline at FLASH. Since none of the RF com- ponents 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 condi- tioning, 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 5.5MW flat top of 400ns operation. Next step will be to include RF pulse compression to achieve the design power of 22 MW.
