ET Enterprises Limited is a new UK company which has taken over manufacture and supply of the Electron Tubes brand photomultipliers and associated hardware to meet the needs of detector users in industry and research around the world. Although a new company, its history goes back to the 1930s when, as part of EMI, it first became involved with light detection technologies and the development and manufacture of photomultipliers which started in the late 1940s. We were one of the first companies to produce a hemi-spherical photomultiplier, which was a 5 inch pmt for the SNO project. This was followed by the first major order for 8 inch hemi-spherical pmts for the BOREXINO project. Then came our biggest order ever for pmts, which was for the BaBar DIRC detector. Our development efforts have also been directed towards rugged pmts for space applications, such as the GRO, SOHO, HIPPARCOS, and INTEGRAL projects. In parallel with this we developed and introduced a range of extremely rugged, high temperature pmts for oil exploration applications. In the Astro-Physics sector we were the first company to develop and introduce a small hemi-spherical photomultiplier for the high-resolution camera of the MAGIC cosmic shower telescope. We have also developed a range of ultra-low background pmts for Dark Matter experiments, including pmts for operation at liquid argon temperatures. Current projects are DAMA, WARP and ICARUS.
