GEOMAGNETIC FIELD EFFECTS ON THE PERFORMANCE OF 8-INCH DYNODE PHOTOMULTIPLIER TUBES

Two different systems have been built to study the geomagnetic field effect on the performance of large area photomultiplier Twin Storage Bedroom tubes.The main characteristics of photomultiplier tubes such as gain, collection efficiency, transition time spread and energy resolution were measured to investigate the effect.This study shows that both

Recently, several new metaheuristic schemes have been introduced in the literature.Although all these approaches consider very different phenomena as metaphors, CHILD TOOTHBRUSH the search patterns used to explore the search space are very similar.On the other hand, second-order systems are models that present different temporal behaviors depending
