I have added a backup of the CERN proto-0 ELOG at TRIUMF, in case ds-proto-daq is unavailable in future.
The backup ELOG is at https://ladd00.triumf.ca/elog-ds/. There are other logbooks hosted in the same place (requiring a username/password), but the CERN |

16 Mar 2020 14:21, Ben Smith, Configuration, Software, New CAEN HV frontend
|
A few months ago I created a new midas frontend for CAEN HV crates. It behaves more like what users expect - changes made through other interfaces (e.g.
ssh or the Java-based GUI) will be reflected in the ODB. The ODB structure is created dynamically based on which modules are present in the crate, and
the parameters that each module supports (e.g. whether you specify a ramp-up rate in V/s or a ramp-up time in s).

After booting, the elog was only showing logs from before July, and was missing the "For Shifters" category. It appears we were loading the incorrect config

For a few days we were unable to access ds-proto-daq remotely. We were also unable to reach the outside world from ds-proto-daq.
To gain more control over the network settings, I have disabled the automatic configuration by dracut. I created the file /etc/dracut.conf.d/no-ifcfg.conf |

|
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). |

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

16 Jul 2019 02:41, Marco Rescigno, Problem, Trigger, Busy handling
|
This morning tried to get some data with Vbias=65 V, which seems better for the SiPM in MB1.
Busy handling still erratic.
At the beginning it seemed to work fine with busy_invert off and busy_enable on. |
|
16 Jul 2019 02:39, Marco Rescigno, Routine, General, run 771, scintillation events triggering on ch11 and ch12 of board0
|
Trigger setup with a threshold of 1500 ADC count wrt to baseline, on just two channels.
This is also to limit the trigger to 50 Hz, since the busy still did not work.
100 K events on disk. |

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. |

12 Jul 2019 07:58, Marco Rescigno, Routine, General, MB1 test in proto-0 setup/day 2
|
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. |
|
12 Jul 2019 06:01, Marco Rescigno, Routine, General, Run 703

Run 703 is being writte on disk.

12 Jul 2019 02:05, Marco Rescigno, Problem, Trigger, MB1 test in proto-0 setup/1

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.

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

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
|
|
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.
|
|
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.

08 Apr 2019 08:31, Thomas, Routine, General, General work - day 1 at CERN

The SDcard is currently required for operation of the device, the ext3/4 filesystem will immediately fail upon removal.

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.
|
|
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.
|
|
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.

19 Feb 2019 16:26, Pierre-A., Configuration, General, Overall HW configuration

For Reference,
I put a simple schematic for the Trigger/Run control.
Bryerton, please have a look. Let's try to issue 3..5 SW trigger before opening the HW trigger. |

13 Feb 2019 16:45, Pierre, Problem, Hardware, A3818 from Marco
|
Checking again Marco's A3818:
- Port #2 (third from top of card) is acting up.
- change the SFP makes no difference.
|
|
08 Feb 2019 12:08, Thomas, Problem, Hardware, Installed Marco's A3818; didn't work
|
I installed Marco's A3818 PCIe card. Didn't seem to work. I got communication errors talking to link 2. The
communication problems didn't happen right away, but happened once the run started.

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)

06 Feb 2019 14:12, Pierre, Configuration, Hardware, Extended Trigger Time Tag (ETTT)
|
Confirmed this ETTT configuration is working.
ETTT Enabled [22..21] = b10
|
|
31 Jan 2019 15:18, Pierre, Configuration, Trigger, Trigger rate
|
Somehow the trigger rate was not matching the trigger source.
Find out that Link 3 was not collecting and possibly holding the fragment assembly in the main thread.
Swap Link3 <-> Link0 on the V1725, restarted.

28 Jan 2019 01:44, Thoms, Routine, Software, Added web display of V1725 waveforms

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. |

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.
