Residual Gas Analysis in Color Cathode Ray Tubes

Experimental equipment for registration of residual gas spectra in color cathode ray tubes (CCRT) and effective method of analysis of getter behavior is described. The construction of computerized facility for CCRT residual gas investigations and analysis of four types (A33EKC, A48 EKB and 51EKE(EJJ)) CCR tubes are presented. The quadrupole mass spectrometer (QMS) allows partial pressure measurements of the gases contained inside the tube. Outgassing process kinetics in the CCRT systems is described by residual gas dependence on time. These investigations allow predicting getter surface and volume changes in the different gas ambient, certificating properties of getters agents and to trawl of the new getters agents.
