Recipe for making a thin film detector

Abstract The thin film detector consists of a thin scintillator film placed perpendicular to the parallel faces of two opposing photo-multiplier tubes and uniquely is capable of responding to the differential energy loss of transiting heavy mass ions (e.g., fission fragments). A step-by-step procedure for fabricating a thin film detector is presented. Testing routines are described and typical results are shown for comparing the relative performance of the finished product with regard to light and heavy ion energy loss response.
