04/08/13	12:40	536	850	-750			Fluctuating from 1.5-3.0 [math]\mu[/math]A on both sense and field.
04/08/13	13:32	536	850	-750			Tripped
04/08/13	13:40	536	800	-750			Set trip threshold to 15 [math]\mu[/math]A. Current tripped within 5 minutes.

04/09/13	10:12	536	900	-750	5	4	Found HV in tripped state, restored sense to 900 instead of 1050, it first tripped when attempting 900 Volts but staged 50 volts increases brought it back without tripping, I observe 30[math] \mu[/math]A spikes at 900 Volts
04/09/13	11:00	536	890	-750	0.1	0	Found HV in tripped state, set HV to 890 any further and 30 [math]\mu[/math]A current spikes occurr, changed trip time from 0.1 to 1.1 sec
04/09/13	13:11	536	900	-750	0.1	0	current is jumping more
04/09/13	13:11	536	890	-750	0.1	0	found HV in tripped state, went back to 890
04/09/13	17:22	536	890	-750	0.05	0.00
04/09/13	17:30	536	970	-750	1.3	1.2	Changed voltage in steps of 10V at a time. Changed ramp rate to 1V/s on sense. Observed some surge currents after voltage stabilized at around 30 - 40 [math]\mu[/math]A for a few seconds.
04/10/13	07:40	536	970	-750	0.115	0.005	Found fields in tripped state, but not sense or guard. Turned on again, current was relatively low.
04/10/13	07:50	536	1080	-750	1.1	1.0	Went up in voltage in 10V increments at 1V/s ramp, monitoring change in average current at each step after voltage settled. Last increment to 1080 saw some surge currents up to 30 [math]\mu[/math]A, but average current is around 1 [math]\mu[/math]A.
04/10/13	10:40	536	1070	-750	0.2	0.3	Found fields in tripped state. Set sense to lower voltage and reset field voltage.
04/10/13	10:42	536	1070	-750	1.3	1.4	Tried turning voltage on sense up to 1080, current and voltage started fluctuating more than usual. Turned voltage back to 1070. Current is still a little higher than when initially started up again at 10:40, fluctuating from 1 to 4 [math]\mu[/math]A.
04/10/13	11:04	536	1050	-750	1.3	1.4	Found Field & Sense HV in tripped state, set Sense HV to 1050 current becomes non zero after a sense wire Voltage of 1000 VOlts
04/10/13	11:25	536	1050	-750	0.2	0.3	tried to increased to 1060 since current fluctuations were small and below 0.2 [math]\mu[/math]A, both sense & FIled tripped so returned to 1050 sense wire voltage setting
04/10/13	12:30	536	1050	-750	0.2	0.3
04/10/13	13:45	536	1070	-750	0.15	0.25	Current instability was observed when taking voltage up to 1075. Backed off to 1040, current stabilized to less than 0.01 [math]\mu[/math]A. Raised back up to 1070V again, current appears stable for the moment.
04/10/13	15:15	536	1070	-750	0.065	0.115
04/11/13	08:30	536	1120	-750	0.065	0.115	Currently raising voltage only 1-3 volts at a time and monitoring sense current for a few seconds before raising again. If sense current stays above 0.075 for more than a few seconds, run-away current instability will usually start-up again.

04/17/13	07:35	536	1020	-750	3	3	during rise to 1175 V, current appeared unstable so I backed off to 1020V where it oscillated between 3 and <1. Letting it settle here before ramping back up to 1205.
04/17/13	12:46	536	1070	-750	0.1	0.2	increased Senve voltage by 20 volts until current fluctuations were seen on the field current

04/17/13	14:48	536	1110	-750	0.01	0.1	some 5uA current spikes are occurring, leave at this voltage overnight.
04/18/13	10:50	536	1160	-750	0.080	0.170	Noticed some possible spiking, getting close to trip current at 1170, scaled back to 1160 and current stabilized within a minute.

04/22/13	17:40	536	1140	-750	0.000	0.050	HV was found in a tripped state a few hours ago. Voltage was ramped up to 1050 a few minutes ago. Just ramped up to 1140 now. Current appears stable at 0.050 on field.

04/23/13	10:00	536	1140	-750	0.000	0.050	Found in tripped state. Reset to previous stable voltage. Some current spiking from 0 - 3, sometimes up to 140 microamps for a split second in the first few minutes after reset.

04/24/13	17:43	536	1400	-750	6.2	6.3	Kraken was removed from SL1 and placed on SL2 to test up to full operating voltage on a burned in SL. SL2 averaged 1.2 microamps after 24 hours of full voltage on with the Kraken. moved Kraken back to SL1. Able to get voltage up much higher now, and current spiking does not occur quite as readily to high levels (e.g., 140 microamps with an average reading of 3 or less microamps). Current trip level is set to 200 microamps on all wires.
