Transport Section

Getting rid of Tritium
STS.jpg

The transport section has to adiabatically guide the beta electrons from the source to the spectrometers, while at the same time eliminating any tritium flow towards the spectrometer, which has to be kept practically free of tritium for background reasons. It consists of a differential pumping section (DPS2F) and a cryogenic pumping section (CPS). In combination they must provide a tritium flow suppression by nine orders of magnitude.
