A Low-Cost X-Band Generator for Microwave Optics Experiments

Gunnplexers are becoming scarce in the surplus market, but X-band motion detection is very much alive.  X-band detection modules are available for OEM applications, and fortunatelly, Parallax has a unit based on this module available for $34.99.

d.i.y. Quantum Dot Synthesis

Experimental chemistry is not our forte, so we prefer to use professionally-manufactured quantum dots for the Schrödinger’s Wave Equation experiments we discuss in the book‘s Chapter 7.  However, if you are interested in synthesizing your own quantum-dot nanoparticle suspensions, we recommend that you take a look at the detailed instructions prepared by  Professor George Lisensky

Prototyping PCB for d.i.y. Photomultiplier (PMT) Amplifier/Processor

We built the bulk of our PMT amplifier/processor/discriminator on a Universal PDIP Operational Amplifier Evaluation Module by Texas Instruments (model OPAMPEVM-PDIP).  Click on the picture above for a full-size version of the picture. The diagram in the following pdf file shows the connection layout for the circuit shown in the book’s Figure 34: PMT Processor PCB

Assembly View of diy Variable-Output, High-Performance PMT High-Voltage Power Supply

We are posting this picture to help you construct the variable-output, low-ripple, high-stability, high-voltage power supply described in pages 38-40 of “Exploring Quantum Physics Through Hands-On Projects.”  The schematic diagrams for this power supply are in the book’s Figure 31.  Output voltage (up to 2 kV) and current (up to 1 mA) are monitored via

X-Band Gunnplexer Microwave Transceiver for Microwave Optics Experiments

This is an inside view of our X-Band Gunnplexer transceiver (book‘s Figure 12) that should help you build your own units if you follow the schematics shown in the book’s Figure 11 .  It is used throughout Chapter 1 for experiments in microwave optics, in Chapter 6 to measure single-slit diffraction, and in Chapter 7 to experiment

MX-10160 Gen III Image Intensifier Tube

This is the surplus Gen III image intensifier tube (an MX-10160 Gen III intensifier tube used in the helmet-mounted AN/AVS-6 “ANVIS” aviation night vision imaging system, which we purchased on eBay®) that we used to build our setup to image interference patterns from our single-photon two-slit setup (book‘s Figure 93).  The tube is supplied by
