Photomultiplier tubes (“PMT”)
Handcrafted glass PMTs are used to convert light into electrical signals. Such tubes are fragile, have high quality variability and require high-voltage for operation. There are only few tube manufacturers worldwide.
Proportional counters & GM tubes (“Geiger counter”)
These counters convert ionization charge into electrical signals. This technology requires high-voltage and is sensitive to vibration.
Key advantages of the semiconductor-based SiPM technology
Standard exterior dimensions are 18.5 cm x 29.5 cm, custom sizes available.
