Vacuum measuring technique is of special importance in the FAIR and GSI accelerator facilities. On the one hand, monitoring the vacuum pressures in the beam tubes is indispensable for the assessment of the generated vacuum quality, which defines the beam losses and thus ultimately the beam life time. On the other hand, vacuum measuring techniques will be used as an input for the interlock system of the machines and is important for the detection and localization of potential leaks. Reliability and durability of the vacuum measurement technology used are therefore important prerequisites for trouble-free operation of the accelerator vacuum systems. The vacuum measurement at FAIR and GSI involves the measurement of pressures ranging from atmospheric pressure down to the operating pressure required in the particular machines. Due to radiation environmental issues, the FAIR and GSI facilities require vacuum gauges without on-board electronics on the gauge head (i.e. passive gauges), only. The gauges must be compatible with remote connection to the controllers with the use of cable lengths between 100 and 300 m.

These gauges are required for different accelerator parts at FAIR,GSI and FZ Jülich (third).
