We have tried to connect the steering module to the DAQ pc via Luigi's USB-Ethernet adapter. 

That does not appear to work. We'll receive another USB-Ethernet adapter tomorrow, and it should be configured to have a static IP address : 192.168.121.1 and NetMask 255.255.255.0
For the time being, we are using Tom's laptop. 

The HV board from Naples did not turn on: Yury gave it to the CAEN guys to check and/or bring back for replacement.

Yi and Luigi rented a new HV module (A1519). The HV module (A1520P) we used for tests of the I-V script is also present in the Mainframe (see below).
The first 24 channels (slots 0 and 1) are therefore HV. If the new HV does not show up on time we'll try and adapt the cables to work with A1519.

The A2517A module is LV. This is currently operated from the DAQ pc using CAEN_HVPSS_ChannelsController.jnlp (located in the Desktop/SteeringModule folder).
The three low voltage channels (0,1,2) should be turned on at the same time by setting Pw = ON.

Settings: 

Channel 0 and 1: I0Set = 2.0 A , V0Set = 2.5 V ,  UNVThr = 0 V, OVVThr = 3.0 V, Intck = Disabled
IMon = 1.44 (this depends on the illumination) , VMon = 2.48 V , VCon = 2.79 V

Channel 2: I0Set = 1.0 A , V0Set = 5.0 V ,  UNVThr = 0 V, OVVThr = 5.5 V, Intck = Disabled
IMon = 0.07 , VMon = 4.998 V , VCon = 5.02 V

In case the channels trip they cannot be ramped back up unless the alarms are cleared.

Lab notes @ CERN

11/10/2020

11:00 – First look at MB2.  Noticed on some of the PDMs that some of the tile PCB are more delaminated than others.  PDM 25 also had the FEB connectors more inserted than any other PDMs.  No other differences noticed.

11:30 – Connected SMU and switching matrix to MB2.  Power w/o steering module.  Checked that all channels match by running photo current tests with and w/o a flashlight on one corner.  Using the computer form Pisa with Labview scripts from Matteo.  Everything is ok.

12:00 – Replace plastic shields around Proto-0 for IV curve measurements in dark conditions.  PDM 1 breakdown is around 63V.  Looks ok.  PDM 2 is over 65V…. Seems high.

12:30 - PDM 6 People walking, disrupted the light conditions.  IV curve will be jagged.  Will go for lunch.  Closing door and turning off exterior lights.  Current will decrease

15:30 – IV curves look fine.  …/MB2_retriveval_CERN/data_files/iv_warm_1

16:00 – Took forward IV curves.  Saved as …/MB2_retriveval_CERN/data_files/forward_warm_1.  They look fine.  Checked old pictures of the lamination of the tile PCB and they have always varied in thickness, from before the LNGS LN test.

16:45 – Power FEBs on to look at noise spectra with 20V bias on the tiles.  

18:00 – PDM 2, 4, 6, and 25 have very odd power spectra.  George said they look like they’re not connected.

18:30 – Saving FFT to disk for analysis.  Saved as …/MB2_retriveval_CERN/data_files/noise_warm_1

19:00 – PDM 2,4,6 and 25 have one of the differential lines disconnected.  Using a light and looking at the differential outputs on the scope, this is obvious.  20V bias and FEBs powered at 5V.  Saved as …/MB2_retriveval_CERN/data_files/waveform_light_1

19:30 – Started another round of reverse IV curves in dark conditions.  Saved as …/MB2_retriveval_CERN/data_files/iv_warm_2

21:15 – IV still going.  EP will come back to shut off the LV supplies

12/12/2020

10:00 – Checking connectivity of all the differential lines.  One side of PDM 6 is not connected.  2, 4, and 25 are connected.  Doesn’t explain what we saw yesterday.  Channel 2 and 4 now are responding to light on both differential lines.  The only thing that has changed is unplugging the external signal cable and plugging it back in.  PDM 6 is the only one now not responding on both lines.

10:30 – Checking the power spectra.  PDM 4 and 6 are bad on both differential lines.  PDM 2 looks fine.  Seems to be non-repeatable.

11:00 – Disconnected the signal patch board from the finger strip.  Holding the patch and reconnecting the entire signal path and pinging now shows PDM 6 and 25 have one differential line disconnected.

11:30 – Checking the power spectra on every PDM channel directly from the fingerstrip with a flat cable.

12:30 – PDMs 2, 4, 6 power spectra from the fingerstrip look normal.  Both connections are there.  Light response is normal.  Channel 13, however, now has one differential line disconnected and the other looks abnormal.  Saving waveform data with 60Hz light on as waveform_light_2.

All of this is pointing to multiple connection issues…

15:00 – It looks like PDM 13 is disconnected from the fingerstrip, or at least it is pulled further away than the others.  This is likely also due to the removal of the patch.  PDM 2 also looks pulled a bit further.

15:30 – Unmounted MB2 and put on the stand to do an optical inspection.  The microscope didn’t allow a close enough look at the wirebonds to search for any broken ones.  A close look by eye didn’t reveal any obvious damage.

16:00 – Packed everything up.  MB2 needs a closer look, likely needs to be disassembled.

Run 747 , 250 k events

as requested by alessandro 40% post trigger, acquisition window 16 us.

Changed custom size to 500 (20 us), tested ok run 681

Tried to get laser sync signal into chronobox (clkin1 input), apparently all triggers dropped by chronobox

Problem is that the same now happen also with the regular setup where the clkin1 signal is taken by the dual timer.

Run 718 has 25 channel readout Board 0 ch 0-15 and Board 0 ch 0-7. 

Laser triggered, some noise, maybe not so bad as is look here.

RMS of baseline is 200 ADC count. Single PE peak is about 100-200 ADC count from baseline.

Looking carefully, some very nice scintillation event are found.

Implemented a simple charge integration on the midas display, most of the channels look almost as good as this one.

Nothing on the daq side changed, a part from the DAC value moved to 5000, allowing a slightly greater dynamic range.

Crew: Edgar Sanchez Garcia, Sam Hill, Simone Stracka, Tom Thorpe, Yi Wang

Morning: Set up equipment for the IV curve measurements. We enable the interlock system in the SMU in order to go higher than 42 V (handle with care).

Afternoon:  Measuring IV curves.  Note there is a voltage drop in the LV cable that needs to be compensated for.  

Chan 1 is set at +3.3V drawing 1.46A; sense line reads +2.39V
Chan 2 is set at -3.3V drawing 1.46A; sense line reads -2.39V
IV curves are scanning from 0-80V in 200mV steps w/ 100uA limit: elog:45/2 , elog:45/3
The two runs are visible ( elog:45/1 for color code and mapping )
Compare to elog:45/4 , obtained when probing individual tiles under more controlled light conditions

Darkside people seem to be doing some tests at CERN next week.  It looks like they aren't going to use our DAQ (they will I think just use CAEN tools).  But we took 
opportunity to make TRIUMF DAQ work again.  There was a couple issues

1) I needed to inver the busy signal for input 0 to the chronobox in order to get any triggers out of the system.  Not sure why; I don't think I had to do that before.  But it is 
working now.

2) The CERN web proxy was not initially working.  Somehow I 'fixed' it by changing the proxy configuration variable of SERVICE_NAME from 'midas' to 'dummy'.  I don't 
understand why that fixed it.  But now you can see the DAQ here:

https://m-darkside.web.cern.ch/chronobox/

I have done a couple longer tests of the DAQ setup.  The runs were done with a high trigger rate of ~60Hz, with
the V1725 asserting their busy to throttle the trigger.

I found that after a couple hours (~5hours) that we would no longer be getting ZMQ packets from the chronobox. 
 You can see this with error message like

15:29:04.092 2019/04/11 [feov1725MTI00,ERROR] [feoV1725.cxx:1033:read_trigger_event,ERROR] Error: did not
receive a ZMQ bank.  Stopping run.
10:26:37.158 2019/04/11 [mhttpd,INFO] Run #657 started

If I start a new run I am still missing ZMQ packets.  However, if I restart the frontend program (and hence
re-initialize the ZMQ link), then the chronobox does start sending triggers again.  So it may be more of a
problem with the ZMQ setup in the MIDAS frontend.  Needs more investigation.
