A long-term aging study of honeycomb drift tubes for the HERA-B Outer Tracker using a circulated and purified CF$_{4}$ gas mixture
The Outer Tracker of HERA-B uses a gas mixture containing CF/sub 4/ to obtain high electron drift velocities. The high cost of this gas makes it necessary to circulate the gas mixture which must then be purified to avoid accumulation of air and pollutants. However, the usage of gas purifiers poses t...
