EMI 9826B Photomultiplier  
Written by AnubisTTP on 2012-06-10  


The EMI 9826B is a small end view photomultipler tube designed for use in the scintillation counters used within positron emission (PET) medical scanners. The 9826B has a peak wavelength of 420 nanometers and is characterized as having a high speed response and immunity to magnetic fields within a relatively compact package. The unusual base is designed to facilitate testing; even though the tube is a flying lead type, it's long gold leads have been welded to a 14 pin button base. This is so the customer can insert the tube into a test fixture for characterization prior to installation in a final device, at which point the button base would be clipped off.
