Abstract :
This presentation summarizes the measurements performed on the ETL 9125FLB17 photomultiplier tubes, used in the particle identification device of the high-energy physics B a B ar experiment. In particular, we show how the performance of the phototubes is degraded by either a magnetic field or helium gas.
