Construction of a d.i.y. Thermoelectrically-Cooled Photomultiplier Tube (PMT) Housing

The photomultiplier tubes (PMT) is the workhorse detector in particle physics and many other fields that require detection of light at extremely low levels.  However, the long-wavelength response of PMTs is not only low because of low quantum efficiency, but also because thermionic emission at room temperature causes swamps low-level signals with noise. Reducing dark counts

diy Scintillation Probe for Ludlum Ratemeters Using Surplus XP3312/SQ PMT

  Ludlum general-purpose ratemeters are professional-grade instruments that are available on the secondary market at affordable prices.  They are compatible with a wide variety of probes, making them a great choice for educators, surveyors, and advanced amateur users.  However, probes for Ludlum ratemeters are often as expensive as the meter instrument itself, making it worthwhile
