Syllabus

# LIN 105 - RF & Microwave Systems for Linacs

## Course Description
This course provides foundational knowledge and practical skills for servicing radiofrequency (RF) and microwave systems integral to medical linear accelerators. Students will explore the principles of electromagnetic wave propagation, impedance matching, and power transmission within waveguides and coaxial structures. Key components such as circulators, isolators, and RF drive chain elements will be analyzed. The course covers the operational theory of accelerating structures and the function of Automatic Frequency Control (AFC) loops. Emphasis is placed on safe handling, measurement techniques, and troubleshooting common faults in high-power microwave systems. This course prepares technicians to maintain critical accelerator subsystems with precision and safety.

## Learning Outcomes
