# Measuring emission current vs time. # 9:13.dat shows peak in current followed by decrease. # Decrease due to venault? Try decreasing venault and see if current increases # Dropped Vv -> 0, Ie -> 0.8 uA # Wait 2 minutes # Increase Vv -> 17.38 # Start 9:43 # t (min) Ie (uA) 0.0 11.9 0.2 13.1 # Maximum reached; very rapidly, then rapid decrease; time is rough estimate only 0.5 12.1 1.0 11.2 1.5 10.8 2.0 10.6 2.5 10.5 3.0 10.4 3.5 10.4 4.0 10.3 4.5 10.3 5.0 10.3 # Stop 9:48 # Notes # The current rapidly decreased when the venault was turned back on. It reached the maximum of 13.1 within 15 to 20 seconds, then decreased. # Seems like when the venault is strongly positive, it accumulates charge. # At 9:50, current is still 10.3; added to end of data # At 9:53, current unchanged 7 10.3 10 10.3 12 10.4
