V. Guidi et al., HELIUM PURITY CONTROL BY THIN-FILM GAS SENSORS AT THE NA-48 EXPERIMENT AT CERN, Sensors and actuators. B, Chemical, 47(1-3), 1998, pp. 54-58
The authors have implemented a system for monitoring the purity of hel
ium for the NA-48 experiment on high-energy physics at CERN. This meas
urement is important for correct execution of the experiment. A set of
SnO2 sensors was used to the purpose for on-line information on heliu
m purity within the required accuracy. (C) 1998 Elsevier Science S.A.
