Technical details and manufacturing context for Bending Magnet

Definition
In a Medical Linear Accelerator, the bending magnet is a critical component that precisely deflects and steers the high-energy electron beam along the desired trajectory within the accelerator structure. It ensures the beam is properly directed toward the treatment head for accurate radiation delivery to tumor targets.
Working Principle
The bending magnet generates a strong, uniform magnetic field perpendicular to the direction of the electron beam. According to the Lorentz force law, charged particles (electrons) moving through this magnetic field experience a force that causes them to follow a curved path, allowing precise control of beam direction and focusing.
Common Materials
Laminated silicon steel, Copper windings, Insulation materials
Technical Parameters
  • Magnetic rigidity - product of magnetic field strength and bending radius, determining the energy of particles that can be deflected (T·m) Customizable
Components / BOM
  • Magnet Core
    Provides the magnetic circuit and determines field shape and strength
    Material: Laminated silicon steel
  • Coil Windings
    Carry electrical current to generate the magnetic field
    Material: Copper conductor with insulation
  • Cooling System
    Removes heat generated by electrical resistance in the coils
    Material: Stainless steel tubing, water
  • Magnetic Pole Pieces
    Shape and concentrate the magnetic field in the beam path region
    Material: Low-carbon steel
Engineering Reasoning
0.5-2.0 Tesla magnetic field strength, 100-500 A excitation current, 20-80°C operating temperature
Magnetic field saturation at 2.1 Tesla (for NdFeB magnets), coil insulation breakdown at 650°C, mechanical deformation at 150 MPa stress
Design Rationale: Magnetic saturation reduces permeability (μ_r drops below 1.05), causing field distortion; thermal expansion mismatch (Δα = 12×10⁻⁶ K⁻¹ between copper coil and steel yoke) induces mechanical stress exceeding yield strength
Risk Mitigation (FMEA)
Trigger Coolant flow reduction below 2.0 L/min (40% of design flow)
Mode: Coil temperature exceeds 155°C, causing insulation degradation (Class H insulation limit)
Strategy: Redundant cooling loops with independent pumps and flow sensors triggering at 2.5 L/min
Trigger Harmonic content in power supply exceeding 3% THD at 300 Hz
Mode: Eddy current heating in pole faces increases by 15%, causing thermal distortion of 0.1 mm
Strategy: Active harmonic filters with 98% cancellation efficiency and pole face laminations of 0.35 mm thickness
