      abstract     = {ALBA is a 3rd generation synchrotron light source located
                      in Spain, in operation since 2012. In preparationfor its
                      upgrade to a 4th generation facility, which requires
                      addressing the significantly reduced Touscheklifetime, ALBA
                      has designed and constructed a higher-order mode (HOM)
                      damped active 3rd harmonic RFcavity. This cavity is designed
                      to longitudinally lengthen the electron bunches, thereby
                      reducing their densityand enhancing the beam lifetime. The
                      design is based on the EU HOM-damped cavity currently
                      employedin ALBA’s main radio frequency (RF) system. The
                      cavity prototype was installed in the BESSY II ring undera
                      collaborative agreement between ALBA, HZB, and DESY,
                      institutions that operate at the same main RFfrequency, 500
                      MHz. This paper presents the first commissioning results,
                      including bead-pull measurements,high-power conditioning and
                      initial beam tests in both single and multi-bunch operation
                      modes. The resultsconfirm that the cavity parameters are
                      consistent with the design specifications, the HOMs are
                      effectivelymitigated, and the anticipated beam lifetime
                      enhancement is achieved, demonstrating the feasibility of
                      thedesigned cavity.},
