The RF system for the Alternating Gradient Synchrotron (AGS) at Brookhaven National Lab (BNL) consists of a Tetrode Based Power Amplifier (PA) driven by a Solid-State Feedback Amplifier (SSFB). Due to the nature of the tetrode, the Screen Voltage is prone to arcing to the Grid. This creates a transient at the Screen Voltage (2kV) which appears on the output of the SSFB damaging the devices....

To support the reliable operation, there have been three RFQs developed at SNS. SNS RFQs are 4-vane type structures designed to accelerate H- beam from 65 keV to 2.5 MeV with estimated transmission efficiency above 90%. The RFQ02 was installed to the SNS Front End and started operating for beam production in 2018. After a few years of operation, field tilts were observed in all four quadrants...

Fermilab’s PIP-II project seeks to enhance its proton beam capabilities for scientific research by modifying the existing synchrotrons and replacing the linear accelerator with a superconducting linear accelerator. To mitigate risks in technology readiness and prepare for operational maintenance, test stands of various complexities were built. Many of the RF components, subsystems, and systems...
