ET Enterprises Ltd (formerly the photomultiplier business of Electron Tubes Ltd) designs, develops and manufactures high sensitivity, low noise photomultipliers for the detection and measurement of very low light levels.
Plowden and Thompson Limited and Tudor Crystal Design Limited.
ET Enterprises has introduced a new Multi-Channel Scaler/Counter-Timer, which is the MCS-CT3. When combined with a PC or Laptop via the USB 2.0 interface, the MCS-CT3 operates as a cost-effective, high performance pulse counting instrument.
The photomultiplier is a very sensitive light detector providing a current output proportional to light intensity. Main benefits are large detection area, high gain and single photon capability.
