The presented report describes the current state of the Cyclotron and summarizes the work that has recently been done in the Cyclotron AIC-144 Department. Work on improvement of the proton beam parameters has been carried out since 2004. The recent upgrading involved the RF generator, control system of correction coils, the vacuum system and ion source. Technical inspection in October 2013 confirmed the effectiveness of the adopted modification. Despite many years of service Cyclotron is in a good operating condition. Implementation of Quality Assurance procedures and timely technical inspections ensure long-term operation of the machine.polReport
