 13 Dec 2018 11:02, Thomas, Routine, Hardware, Testing V1725 digitizers
|
Couple weeks of work documented in one elog...
V1725 serial numbers: 455, 392, 460, 462, 474

09 Jan 2019 12:22, Thomas, Routine, General, V1725 LVDS outputs
|
Pierre figured out that NIM crate not working. We now see LVDS outputs from the individual channels firing.
Each set of two different channels is ganged together into a single self-trigger output. By setting the
register 0x1n84 to 3 we enable so that if either input channel fires then the self-trigger for that group fires.

11 Jan 2019 11:07, Thomas, Routine, Digitizer, Data corruption for ADC channels 
|
I modified the analyzer so that it shows data from all four modules.
I find that there is evidence of corruption of the V1725 ADC data on a couple channels. You can see an example of a waveform with corruption in the attachment. |

17 Jan 2019 15:47, Thomas, Routine, Hardware, Added raided HD to ds-proto-daq
|
Added pair of 10TB hard-drives in raid-1 to ds-proto-daq. MIDAS data files will get written to this raid volume.
[dsproto@ds-proto-daq tmp]$ df -h /data

21 Jan 2019 13:05, Thomas, Pierre, Routine, Digitizer, Tests of V1725 baseline and triggering
|
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
|
|
28 Jan 2019 01:44, Thoms, Routine, Software, Added web display of V1725 waveforms
|
I added javascript webdisplay of the V1725 waveforms to the Darkside setup. You can see the waveform display here:

07 Feb 2019 17:30, Thomas, Routine, Software, Testing the maximum data throughput
|
First check the maximum trigger rate and maximum data rate for different sample lengths (for each channels):
sample length Maximum rate MB/s CPU % (per thread)
|
|
05 Mar 2019 10:36, Thomas, Routine, Digitizer, Switched to standard V1725 firmware
|
It turns out that the ZLE V1725 firmware we are using only supports reading out up to 4000 samples per channel.
We need 80000 samples to readout 200us, which is requirement.

05 Mar 2019 14:20, Thomas, Routine, Hardware, Installed network card
|
I installed a PCIe 1Gbps network card and configured it as a private network. The PC (ds-proto-daq) is
192.168.1.1. I guess we can make the chronobox 192.168.1.2.
|
|
06 Mar 2019 14:16, Thomas, Routine, General, Retested the chronobox trigger logic
|
I retested the chronobox trigger generation:
1) Inserting moderate sized pulse into channel 8 of V1725-0.
|
|
06 Mar 2019 15:10, Thomas, Pierre, Routine, Trigger, Setup of chronobox
|
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

 06 Mar 2019 18:19, Bryerton Shaw, Routine, Trigger, Setup of chronobox
|
The SDcard is currently required for operation of the device, the ext3/4 filesystem will immediately fail upon removal.
|
|
11 Mar 2019 12:30, Thomas, Routine, Trigger, New chronobox firmware; run start/stop implemented
|
a) Bryerton implemented new version of the firmware. New features:
1) run start/stop state
|

03 Apr 2019 15:11, Thomas, Routine, Software, CERN SSO proxy for ds-proto-daq
|
Pierre and I got the CERN proxy setup for the Darkside prototype.
Using your CERN single-sign-on identity, you should be able to login to this page
|
|
03 Apr 2019 15:31, Thomas, Routine, Software, test of elog
|
| The last elog didn't go out cleanly. Modified the elogd.cfg to point to the proxy. Try again. |

08 Apr 2019 08:31, Thomas, Routine, General, General work - day 1 at CERN
|
Notes on day:
1) Fixed the problem with the network interfaces. Now the computer boots with the correct network configuration; outside world visible
|
|
10 Apr 2019 05:40, Thomas, Routine, General, General work - day 3 at CERN
|
Several points:
1) Gave a series of tutorial on DAQ to DS people yesterday and today. Got a bunch of feedback, which I will pass on when I'm back at TRIUMF.
|
|
11 Apr 2019 08:20, Thomas, Routine, Trigger, Missing ZMQ banks
|
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.
|
|
02 Jul 2019 18:01, Thomas, Routine, Software, MIDAS running again
|
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
