LB-7 employs the latest RF system technology in the industry, utilizing a solid-state RF source composed of multiple power amplifier modules. This replaces traditional vacuum tube RF sources, significantly improving the stability of the RF system. Since each power amplifier module operates independently, damage to one module will not cause a system outage, further ensuring the stable operation of the cyclotron.
