A source of high voltage negative to fotomultiplicadoras with control system and remote monitoring

摘要

A source of high voltage negative to fotomultiplicadoras with control system and remote monitoring. The present invention relates to a source switched high voltage negative with remote monitoring system for feeding multiple anodes (mapmt photomultiplier tubes).The fountain was based on a model of the positive high voltage, modified to provide overtones of - 500 V to - 1000 V and a maximum current of 500 Au. A prototype was mounted on a printed circuit board with low cost components and easily found in the market.This prototype has as objective to conduct stability tests and noise with different loads and input voltages and observation of the high tension produced, as well as the supply voltage of the source and the ambient temperature. The results of the tests and tests have shown that the source has high stability, low power consumption and excellent regulation.The portability of the source also allows the application in field tests (through the use of a 12 volt battery), and may be used in the context of fundamental research and didactic way in laboratories of physics experiment.
