Abstract:
Ocular melanomas have been treated for the last 20 years at the Helmholtz-Zentrum Berlin in collaboration with the Charité – Universitätsmedizin Berlin. Howev-er, parts of the initial control system electronics date back to the 1970s, when the machine was installed. Facing a critical shortage of legacy and obsolete com-ponents and with the down-time due to failures in the electronics on the increase, a decision was made to install the digital low-level RF control system, devel-oped by iThemba LABS, on our k=132 cyclotron. A short description of the installation and commission-ing process, which occurred in April 2017, and the experiences of the first two years of operation with the new digital low-level RF control system is presented
