Abstract

Abstract: Negative ions compact cyclotrons serve many applications and are known to be effective due to their simple and efficient extraction as well as the large circulating currents without the requirement of separated turns. TR30s are compact cyclotrons that have continued to experience impressive technological advances over the last few decades, driven primarily by medical isotope production needs. Their space charge limits are in the range of 1 to 2 mA, and we explored the combination of our machines' age and the challenges of maintaining their performances. Certain subsystems are detailed with specific examples from more than 30 years of around-the-clock, quasi continuous operations with TR30 cyclotrons. The subsystems' failures and their part in the overall downtime will be presented.
