Cosmic Watch Muon Detectors - LabWiki

Dieser Myonen-Detektor scheint mir ein interessantes Bastelprojekt für den Physikunterricht zu sein.

Leider konnte ich nur englische Informationen dazu finden.

The CosmicWatch Desktop Muon Detectors are an MIT based undergraduate-level physics project that incorporates various aspects of electronics-shop and machine-shop technical development. The itself is a self-contained apparatus that employs plastic scintillator as a detection medium and a silicon photomultiplier for light collection. These detectors can be battery powered and used in conjunction with the provided software to make interesting physics measurements.

Aus der Cosmic Watch FAQ:

What are the benefits of this detector over conventional instructional muon detectors?

  • It is fully self-contained: you don’t need a HV power supply, NIM modules, oscilloscopes…
  • It is efficient. We draw less than 1 watt per detector.
  • It is USB powered. You can also use a 5V power connector on the barrel jack. We sometimes use a cell phone spare battery to run the detector.
  • It is light-weight. The current detector weighs 68 grams.
  • It is not expensive. Our students build the detectors for sub-100$/unit.
  • The software is simple. We save the data through the USB connection using the website or running a simple python program.
  • It is expandable. The Arduino allows students to implement their own hardware. We’ve had students add on bluetooth connectivity, SD card readers, and temperature sensors.
  • It’s a lot of fun. Try climbing a mountain with it.
  • It makes a photon measurement. We measure the pulse amplitude, and are able to see single photons with the upcoming device.
  • It’s a fantastic science toy.
  • The build time is short. Our first time students can typically build on in under 3 hours (with supervision). We can build one in under an hour.

Es gibt wohl auch ein CosmicWatch v3, soweit ich verstehe aber aktuell nur für JuniorLab am MIT.

    Also sie entfernen alles was an dem Versuch Spaß macht >:(

    Edit: Und ich weiß ja nicht, keine PMTs. Ja es gibt mittlerweile neuere Einzelphotonen-Detektoren auf dem Markt, aber PMTs sind nun mal immer noch das standard Laborequipment und ich denke, dass es schon wichtig ist, dass die Studierenden mit diesen im Rahmen eines Praktikums mal gearbeitet und diese auch mal in einem Protokoll beschrieben haben.
