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.
04/08/13	13:45	536	750	-750			Sense/field fluctuating around 1.5 [math]\mu[/math]A.
04/08/13	14:40	536	750	-750	2	2	HV found in tripped state, set Imax to 100 [math]\mu[/math]A, and restored HV.

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.

04/16/13	16:50	536	1205	-750	5.0	5.1	Current is fluctuating around 5, but not entirely stable. No observed large spikes above 6.
04/17/13	07:35	536	1205	-750	0	0	found in tripped state.
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.

04/19/13	15:28	536	1020	-750	0.080	0.170	Found HV in tripped state, wouldn't restore to 1100 Volts without tripping so set to 1020 for weekend, current spikes began around 1050 volts
04/19/13	20:20	536	1000	-750	0.080	0.170	Found HV in tripped state, restored to 1000
