For advice on the choice of the scintillator, readout method and photodetector, as well as for scintillator orders, please contact C. Joram (78909)
The group possesses expertise in the machining and polishing of plastic scintillators, light guides and fibres. We build scintillation counters, incl. light guides (fish tail, adiabatic, WLS bars & fibres), and support CERN users in the selection and acquisition of scintillators.
For devices of relatively small area (e.g. 10 x 10 cm2) and thickness (up to 1 cm), we maintain a stock of standard scintillator sheets.
For larger devices or specific scintillator types, we normally work with the suppliers Saint Gobain (formerly Bicron) and Eljen Technology. Delivery delays are of the order 8 weeks, but depend on complexity and volume of the order.
Scintillating and WLS fibres can be ordered from Kuraray or Saint Gobain.
Important: For all jobs, please fill the Work Request Form (MS Word,PDF), print it and bring it to the scintillator lab (hall 187).
For the choice of the photomultiplier tube, you may consult the websites of Hamamatsu and Electron Tubes. Photonis, formerly Philips, do not produce PMTs any longer. The ET site lists some data sheets of Photonis tubes to which they provide an equivalent device. As a further alternative, consult the webpages of the Russian supplier MELZ FEU (contact info@melz-feu.ru).
