Jan 13 2012 10:27:12:607AM	1120113001	Steve Wolfe	Setting up for gas tests using the new Piezo Valves on B-DIV and H-div. Bring up PCS (live) and turn seg2 off, rename SEG01 to "Gas tests 2012/01/13" On ALL_Vs screen: Draw PG6 (B-DIVERTOR) waveform as 50V trapezoid followed by step to 100V, and ramp down to 0 at -2. For PG7 (H-DIVERTOR) drag same waveform to -1.5sec These will test the waveform generation, with no gas. For gas tests, I will want to look at turn on delays, so I'll change the onsets to vertical. Load at 13-Jan-2012 10:26:58.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done
Jan 13 2012 10:51:41:993AM	1120113001	Steve Wolfe	Shot#1 with no pressure in the H-bot plenum B-DIV and H-DIV Hybrid enabled at the PLC Piezo boards set for chopper mode. Ratiomatic on Shouldn't have any gas, just look at waveforms. Still setting up scopes Result: Gas fault on TORVAC PLC, Got waveforms on demand signal outputs 22 and 23 as programmed. No, i.e. zero, drive monitor or plenum signals.
Jan 13 2012 11:05:26:280AM	1120113002	Steve Wolfe	Shot#2: don't understand why there was a gas fault. Try again with no changes, see if it goes this time. It may need the H-bottom plenum enabled? Result: HV enable light comes on briefly in pulse, then gets a gas fill fault and turns off Yuri is going to look at the logic
Jan 13 2012 11:15:13:573AM	1120113003	Steve Wolfe	Shot#3: Yuri is going to look at the plc logic during the cycle, no changes yet, so it's still going to fail. Yuri had bypassed the fault, so it didn't come up, but the HV enable light came on and went off, as before, no permissive no HV
Jan 13 2012 11:21:36:050AM	1120113004	Steve Wolfe	Shot#4: Yuri is debugging, taking out one possible fault rung at a time. Result: gas fault, enable removed
Jan 13 2012 11:33:44:460AM	1120113005	Steve Wolfe	Shot#5: Yuri is debugging, taking out one possible fault rung at a time. Result: It looks like there is logic in the plc associated with the non-existent main plenums for bdiv and hdiv that has not been bypassed. Yuri is going to try to bypass these.
Jan 13 2012 11:43:19:603AM	1120113006	Steve Wolfe	Shot#6: Yuri bypassed the rungs with the nonexistent plenums Result: Hv enable came on and stayed on. Signal seen from H-div, digitizer starts after -2sec, so misses the B-div signal. Next: change waveforms a little, move bdiv
Jan 13 2012 11:57:07:160AM	1120113007	Steve Wolfe	Shot#7: Moved the waveforms, put in a back porch at 10V to see if it still chops near the bottom Result: success, all looks normal Next: put in gas (4psi neon in H-bottom plenum) draw sharp onset 50V .2sec waveform on B-div, starting at -1sec
Jan 13 2012 12:18:21:763PM	1120113008	Steve Wolfe	Shot#8: put in gas (4psi neon in H-bottom plenum) draw sharp onset 50V .5sec waveform on B-div, starting at -1sec Copy to H-bot and H-div Enable only B-div Note: H-Bot plenum output enabled, not B-div or H-div I think this refers to the main plenum, not the Goetz plena. Load at 13-Jan-2012 12:08:00.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Result: Got gas, on the five scale on IGT Plenum signal on B-DIV plenum is in the bit noise, and is coming out negative. -.02V. I guess we should have used the 10Torr gauges? The MKS gauges show a peak of 0.84 Torr-liter Rise in the ratiomatic starts at -.74sec, about 200msec delay peaks about -.23 sec. Seems long, maybe it's reasonable. Next: repeat with gate valves closed for 25 sec in pulse to get a good calibration.
Jan 13 2012 12:27:44:133PM	1120113009	Steve Wolfe	Shot#9: repeat with gate valves closed for 25 sec in pulse to get a good calibration. Result: MKS gauges claim 1.05 Torr-liter, which implies 2 T-l/sec for 0.5sec at 50V demand and 4psi. plen_bdiv gives -.024 change, which is in the bit noise. Well, it's not so bad if you smooth it, modifying the gas_input scope shows about 1Torr-l Next: Same puff from H-div, others all off.
Jan 13 2012 12:33:33:190PM	1120113010	Steve Wolfe	Shot#10: Same puff from H-div, others all off. Result: got gas, Seem to have gotten a little less, MKS shows 0.87 Torr-l plen_hdiv gets 0.84 Torr-liter (with nominal calibration) Next: try H-bottom, this will be on the software chopper
Jan 13 2012 12:51:27:890PM	1120113011	Steve Wolfe	Shot#11: try H-bottom, this will be on the software chopper Result: Hardly any pressure rise. Drive signal looks like it's only outputting 60V at the top of the chop. Pressure rose to low e-6 scale on IGT, torus MKS gauges show ~.02Torr-liter Looks like there has been a change in the response of the piezo driver or the AFOL since the last time we used this. Willy and Roza will check in the cell.
Jan 13 2012 01:22:37:837PM	1120113013	Steve Wolfe	Shot#13: Enable B-top (and its plenum) to compare outputs of another valve in analog mode Should be 16msec at 100V Result: That gave full amplitde Next: swap boards downstairs, B-top and H-bot
Jan 13 2012 01:29:22:183PM	1120113014	Steve Wolfe	Shot#14: Enable B-top and H-bot with swapped boards downstairs, B-top and H-bot Result: same pathology, it didn't swap. Got 5.5V on H-bot and 10V on Btop Next: Willy and Roza will take the BNC off and check a) the loading from the valve b) response to 125kHz at the AFOL input
Jan 13 2012 01:29:46:490PM	1120113014	Steve Wolfe	Shot#14: Enable B-top and H-bot with swapped boards downstairs, B-top and H-bot Result: same pathology, it didn't swap. Got 5.5V on H-bot and 10V on Btop Next: Willy and Roza will take the BNC off and check a) the loading from the valve b) response to 125kHz at the AFOL input
Jan 13 2012 01:35:05:283PM	1120113015	Steve Wolfe	Shot#15: Enable B-top and H-bot with swapped boards downstairs, B-top and H-bot but BNC to piezo off of H-bottom to check loading Repeating same as shot #14 Result: Again H-bot shows 5.55V Also the Hybrid enable light on H-div went off after the pulse, but the B-top enable did not.
Jan 13 2012 01:38:20:040PM	1120113015	Steve Wolfe	Shot#15: Enable B-top and H-bot with swapped boards downstairs, B-top and H-bot but BNC to piezo off of H-bottom to check loading Repeating same as shot #14 Result: Again H-bot shows 5.55V Also the Hybrid enable light on H-div went off after the pulse, but the B-top enable did not. Next: swap the fibers, to test if the H-bot AFOL is not going full range. That was not verified on earlier test.
Jan 13 2012 01:54:51:407PM	1120113016	Steve Wolfe	Shot#16: swap the fibers, to test if the H-bot AFOL is not going full range. That was not verified on earlier test. Disable B-top and Enable H-bot (with the signal from B-top AFOL) Result: Got 9.4 V on the H-bot monitor. This implies the problem is the AFOL. Repeat with B-top also enabled and the plenum pumped out
Jan 13 2012 02:00:24:807PM	1120113017	Steve Wolfe	Shot#17: Repeat with B-top also enabled and the plenum pumped out Result: Get 5.5V out of the B-top signal, which means the problem is in the AFOL. Next: Try replacing the AFOL transmitter for Ch 17-20, of which The H-bot is on channel 19.
Jan 13 2012 02:47:03:700PM	1120113018	Steve Wolfe	Shot#18: Willy is going to replace the AFOL board on 17-20 with the one from 29-32 which was unused. Result: Btop piezo monitor signal reads 8.2V, the input as digitized on the ACQ196_1 reads 9.85 volts on the H-bot input, which is feeding the B-top piezo. THe H-bottom piezo, which is seeing the pulse for B-top, reads 9.34V Willy is going to take the original AFOL card to the shop and check it on the bench at 10V input
Jan 13 2012 04:30:31:727PM	1120113018	Steve Wolfe	Shot#101: Bench testing failed. Back in the interface room I will run a dpcs test shot to leave 10V on output 19 and also on output 32. I'll need to turn off the software fizzle detector so it doesn't take out the signal Draw output ending at 100V on output_19 and 10V on output_32 Turn off dpcs_fizzle Verify I'm only running segment 1 Acknowledge the warning about disabling the fizzle. IDL> test_init_dpcs2,1120113101 Shot ran, I think output_19 stayed high, but nothing from output 32. Maybe the gain is set to zero? Yes, the gain is undefined, as are the phys_limits. But the result on output_19 is 125kHz right where it should be The AFOL (this is the swapped one) is just fine, despitr the fact that the board downstairs only interprets it as 8.2V (or did) Next: Set Gains on output_31 and 32 to be the same as on 19, and copy the waveforms over.
Jan 13 2012 04:46:28:760PM	1120113018	Steve Wolfe	Shot#102: Set Gains on output_31 and 32 to be the same as on 19, and copy the waveforms over. Set Gains to 0.1, phys_limits to [0.,100.] Verify limits =[-10.,10.] oad at 13-Jan-2012 16:33:14.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done Take test shot #102 Worked on 32, stillnot on 31 And it came out 1.0V on 32, instead of 10V. I don't see what's wrong and my workstation or kde is dying. I can't bring up another scope
Jan 13 2012 04:46:35:233PM	1120113018	Steve Wolfe	Shot#102: Set Gains on output_31 and 32 to be the same as on 19, and copy the waveforms over.

Jan 13 2012 06:46:09:040PM	1120113018	Steve Wolfe	Shot#102: Tryng to understand what happened to the output_31 and output_32 waveforms on #102, it looks like the 100V waveform was not loaded. I had a 10.0 V signal loaded on output_32, with a gain=0.1 and a zero waveform on 31. I think the waveforms are from 101, which seems to correspond to the timestamp on the node of 13-JAN-2012 16:14:12.32 I guess I didn't load it until #103. Well, I did do a load of something at 16:33:14, according to the cut and paste in the logbook entry, but maybe I didn't hit apply on the ALL_V screen? Or maybe the X problem was already setting in. Of course, now I've blown away the PCS so I can't scroll back to look at the terminal messages.
Jan 13 2012 05:06:50:670PM	1120113019	Steve Wolfe	Shot#19: Loaded with a ramping waveform on output_19, still have the 31 and 32 as before Next: Use an analog ramp on 19, i.e. turn off dpcs_piezo_chopper for h-bot
Jan 13 2012 05:40:35:497PM	1120113020	Steve Wolfe	Shot#20: Loaded with a ramping waveform on output_19, but remove H-Bot from dpcs_piezo_chopper list still have the 31 and 32 as before Result: Ch19 Ramps up to 9.80V at -.511sec, then FALLS back abruptly to 8.2V at -.5sec. The corrsponding MOUT voltages are 9.75 and 9.85V Next: do another test shot to leave the output full on
Jan 13 2012 05:46:47:267PM	1120113020	Steve Wolfe	Shot#103:do another test shot to leave the output full on on output_19, so Willy can retune the AFOL Copy ch 31 into ch19. Load at 13-Jan-2012 17:41:51.00 Open tree /home/wolfe/pcs_scratch -1 Open tree done test_init_dpcs2,1120113103 That seems to work, got to 9.85V on 19; should be sitting there. Also, output_31 and output_32 went to 9.83 and 9.92 Volts this time. I have no idea what changed from #102. This is worrisome as well.
Jan 13 2012 06:03:44:527PM	1120113020	Steve Wolfe	Shot#103:do another test shot to leave the output full on on output_19, so Willy can retune the AFOL Copy ch 31 into ch19.

Also, output_31 and output_32 went to 9.83 and 9.92 Volts this time. I have no idea what changed from #102. This is worrisome as well. Willy and Roza readjusted the AFOL so the output is 123.9kHz, which is not saturating the receiver, according to the led indicator. Next: Take a final test shot, with the shot from 1120106033 reloaded.
Jan 13 2012 06:06:50:503PM	1120113020	Steve Wolfe	Shot#104: Take a final test shot, with the shot from 1120106033 reloaded. This should put everything back to zero, restore the dpcs_fizzle and put H-bot back in the dpcs_piezo_chopper list Result: I think it worked. Scope MOUT values look normal on all channels I still have the gain and phys_limits set on output_31 and output_32.
