The Hamamatsu Photonics R13194 is a side-on photomultiplier tube designed for vacuum ultraviolet light detection. It features a cesium iodide (Cs-I) photocathode and a magnesium fluoride (MgF2) window, providing a high quantum efficiency of 26.0% at a wavelength of 121.6 nm. The anode sensitivity is rated at 1.0 vó 10^5 A/W, with an excellent solar blind spectral response, achieving a sensitivity ratio of 8500 when comparing 121.6 nm to 300 nm. This photomultiplier tube is suitable for applications such as atomic emission spectrophotometry, VUV-UV spectrophotometry, and the observation of UV plasma in vacuum environments. It operates effectively within a temperature range of -30 to +50 ¬8C and has a maximum supply voltage of 1250 V, with an average anode current limit of 150 mA. The device has a compact design with a minimum effective area of 4 vó 9.5 mm and a weight of approximately 25.5 g. Engineers considering this product should note its high sensitivity and suitability for specific UV detection applications, making it a valuable component for projects requiring precise light measurement in the vacuum ultraviolet range.
