09.16 Pirani 1.00e-3 mbar IE514 8.77e-8 mbar Leak tester c. 5e-12 mbar.l/s (leak tester valved off) 09.48 Pirani 1.00e-3 mbar IE514 8.67e-8 mbar Leak tester c. 3.5e-12 mbar.l/s (leak tester valved off) 10.33 Pirani 1.00e-3 mbar IE514 8.55e-8 mbar Leak tester c. 4e-10 mbar.l/s (leak tester connected to CARME roughing line) 10.55 Leak tester remains at few e-10 mbar.l/s - we do not understand why With leak tester in differential mode the highest reading around the COF600 seal is c. 3.5e-12 mbar.l/s Following checks elsewhere on the chamber we observe c. 6e-12 mbar.l/s which presumably reflects accumulation of He around the chamber Dispersing He with compressed air reduces diff mode reading to c. 2e-12 mbar.l/s 11.00 Pirani 9.80e-4 mbar IE514 8.47e-8 mbar 14.49 Pirani 1.00e-3 mbar IE514 7.71e-8 mbar Leak tester isolated from CARME backing line - CARME Edwards scroll pump now backing turbo.
