The DAQ seems to be ready for tests with proto-0 tomorrow.  

I had to invert the first busy input in order to get chronobox to produce triggers.  I modified the setup script

setup_chronobox.sh

so this is now the default.  Not sure why necessary.

Another interesting fact; it seems the chronobox only asks for a DHCP IP when it first boots.  I think that
chronobox and ds-proto-daq were rebooted at the same time; ds-proto-daq dhcp server was probably not running
when chronobox asked for IP.  chronobox got IP fine when it was power cycled.

A little progress on a couple fronts:

1) We got the baseline DAC setting working correctly from both the CAEN command line tool and from the MIDAS
frontend.  Needed to add some extra sleep before the DAC settings were modified.

2) We figured out how to set the threshold for self-triggering on each channel. It is actually register 0x1n60
for this firmware.  The threshold is defined relative to the online calculated baseline. The threshold is
settable from the ODB.  However, the polarity of the triggering is currently hard-coded to be negative (bit 6 of
register 0x1n64).

3) We could confirm that the LVDS outputs from the V1725 appeared and disappeared as expected when the
self-trigger threshold was changed.

4) We added some basic documentation in Markdown here:

https://bitbucket.org/ttriumfdaq/dsproto_daq/src/master/

Summary of setup of chronobox on network (mostly done by Pierre):

1) Hook up USB connection from chronobox to ds-proto-daq.  Start serial-USB connection by doing

/home/dsproto/online/dsproto_daq/serialusb

can login through serial link.  Added the ssh key for dsproto@ds-proto-daq to the authorized_keys file on
chronobox linux.

ctrl-a, ctrl-x to stop picocom

2) On ds-proto-daq, setup dhcpd server.  Configuration in this file

/etc/dhcp/dhcpd.conf

dhpcd is bond to the second NIC only.  Configure DHCP to give IP 192.168.1.3 to chronobox.  In /etc/hosts set
192.168.1.3 to have hostname chronobox

Power cycle chronobox; it successfully gets IP:

[dsproto@ds-proto-daq dsproto_daq]$ ping chronobox
PING chronobox (192.168.1.3) 56(84) bytes of data.
64 bytes from chronobox (192.168.1.3): icmp_seq=1 ttl=64 time=0.180 ms

3) Can see the chronobox webpage locally as

http://chronobox:8080

4) Some esper tool to access data:  did following to setup esper

  734  yum install python2-pip
  735  pip install esper-tool
  736  yum install ncurses
  738  yum install ncurses-devel
  739  pip install esper-tool

Can then connect to the chronobox by doing

esper-tool interactive http://chronobox:8080

This is as much as I understand at this point... more exploring now...

5) Pierre unplugged the SD card to take it back to Bryerton's room.  But I guess this was bad.

lots of errors on serialUSB link now and the webpage doesn't work anymore:

I added javascript webdisplay of the V1725 waveforms to the Darkside setup.  You can see the waveform display here:

https://ds-proto-daq.triumf.ca/CS/webdisplay

You can also see the webdisplay that comes built into the JSROOT webserver here:

For Pierre: I went through and reset the baselines for all the channels.

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.
