I recently purchased an educational kit of parts from an Ebay auction. The plastic carrying case is labled, "Electron Spin Spectrometer". Inside the case is a tunable waveguide, some microwave diodes, and a device that I can not identify. It is basically a chunk of aluminum with waveguide mounts on oposite sides, and thick glass windows at each waveguide slot. The device was made by Westinghouse, and the model number "WL-1Q22" is printed on the top aluminum dome. By viewing through the windows, I can see all the way through this device, and there is a copper post inside the chamber. Could someome please tell me what this device is? I have no documentation with these parts. I bought it to learn about microwaves and waveguides. Here is the link to the auction, so you can see photos of this misterious device. THANKS!
