In the process, one wants to measure detector performance with gradually changing light guide parameters such as location and length of reflector to be inserted in the light guide. For a light guide, a hard plate like an acrylic plate is generally used. However, it is not easy to make slots in the plates for reflectors to control light spread and it is almost impossible to change, for example, the position of the slots in the same plate. The light guide we propose is made of silicon rubber, RTV rubber. It is known as a coupling material for scintillators because of its transparency and similar refractive index to the scintillators. That is a good character as material of a light guide. To make a light guide of the RTV rubber, what we should do is keep it into favorable shapes until becoming rubbery. Once it became a rubber, we can cut it freely with a cutter or scissors. Reflector insertion process is also easy. The process will be, make a cut into the rubber, bend the rubber to open the part, and set a reflector. Different from an acrylic plate, surfaces of the rubber is a little bit sticky so that the reflector does not move easily. To restore the cut to change its position, one should only put a thin coating of additional RTV rubber in the cut. We also demonstrated advantage of this convenient light guide using the 4-layer DOI PET detector we previously developed., IEEE2013参加・発表}, title = {A Convenient light guide for trial production in its optimization process}, year = {2013} }
