Abstract/OtherAbstract:
|
We present a simple modification for thermoelectrically cooled photomultiplier tube (PMT) assemblies that eliminates the magnetic interference between the peltier element and the PMT. An active compensation is accomplished by forming current loops of the wires of the peltier element and placing them in such a way that they eliminate the interfering magnetic field. It is demonstrated that the improved system reduces measurement errors of the order of 1% to statistical noise at the level of 0.07%. |
