  The synchrotron light source BESSY went into operation for users in 1998. BESSY was not designed initially to allow for Top Up operation, a mode where lost electrons are replaced after minutes while the beam shutters are open and users take data. Since 3 years the facility is improved in order to guarantee safe operation in this risky mode. The work culminated in a one week long Top Up test run at the beginning of this year. The efforts and achievements are described in detail: Improvements of the injector, the pulsed injection elements, the timing system, insertion devices, the additional safety interlocks, and the shielding of the ring.
