Date Time (24h) Guard (V) Sense (V) Field (V) Sense ([math]\mu[/math]A) Field ([math]\mu[/math]A) comments
04/08/13 12:27 536 1100 -750 Tripped (trip is set to 10 [math]\mu[/math]A). Initially settled around 4-5 [math]\mu[/math]A.
04/08/13 12:36 536 950 -750 Tripped
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 07:34 536 750 -750 0.1 0
04/09/13 07:35 536 800 -750 0.1 0
04/09/13 07:35 536 900 -750 0.2 0.3

04/09/13 07:37 536 1050 -750 6.2 6.3
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.

04/18/13 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.

04/24/13 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.
04/24/13 17:53 536 1050 -750 3 3 Found fields in tripped state. Reset and turned down sense voltage to 1050. Still observing some current instability a few minutes after setting the voltage to 1150 initially and turning down to 1050.

04/25/13 16:35 536 1190 -750 3.2 3.3 Unstable current started when going up to 1200V. Averaged 3-13 microamps at 1200V. Average reading is closer to 3 at 1190V.
04/25/13 16:35 536 1170 -750 10 10 Current went up to 12-20 microamps at 1190V after a couple minutes. Scaled back to 1170V.
04/25/13 16:40 536 1180 -750 0.000 0.080 Current stabilized to almost 0 at 1170. Went back up to 1180. Slight rise in field current from 1160V.
04/25/13 16:55 536 1190 -750 0.000 0.095 Temporary spiking above 0.095 on fields. Average reading is stable.

04/25/13 17:41 536 1200 -750 9-30 9-30 Reading is unstable, average ranges from 9-30 microamps.
04/25/13 17:47 536 1200 -750 0.000 0.085 Reading has been stable for 3 minutes at 0.085-0.090 on fields.

04/25/13 17:56 536 1205 -750 0.000 0.090 Reading has been stable for 6 minutes. Leaving at this voltage for the night.
04/26/13 10:05 536 1240 -750 0.000 0.09 current was 0.5 , increased voltage from 1205 to 1220 in 3, 5 volt steps and 1V/s increases
04/26/13 16:02 536 1230 -750 0.000 0.09 the HV did not trip but the current was fluctuating up to 2 muA so I lowered the HV to 1230 and the current went down to 0.09 on Field.
04/27/13 15:40 536 1240 -750 0.000 0.07 I started seeing what may be signals on the scope at this HV but they look too narrow 042713 S6 1240HV.png
04/29/13 07:40 536 1250 -750 0.000 0.07 HV stayed up 1240 over the weekend, increase another 10 volts.
