However, 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 components 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, developed by iThemba LABS, on our K=132 cyclotron. A short description of the installation and commissioning process, which occurred in April 2017, and the experiences of the first 2 years of operation with the new digital low-level RF control system is presented.
