OpenPCBLGR

Open-Source Loop-Gap Resonator for X-Band EPR Spectroscopy — Rev 1.0

Open-hardware design for a PCB-based loop-gap resonator (LGR), by Thorsten Maly (@thmaly).

Contents

  • KiCAD/ — PCB source files and gerbers (resonator top/bottom, coupling loop)
  • Model/ — mechanical parts: SolidWorks, STEP, and 3D-print (STL) files
  • Manual/ — assembly instructions, BOM, and workshop presentation

Documentation

Full build documentation and background: [docs site — TODO]

Quick Start

  1. Order PCBs from the gerber files (e.g. JLCPCB) — no modifications needed for stock builds
  2. Print/machine mechanical parts from Model/
  3. Follow the Assembly Manual
