15:00 → 15:15 Pre-production hardware/PRR preparation

DUNE AFC v4 status

MIB v3 status

FIB v2 status

GIB v2 status

Documentation status

Speakers: David Cussans (University of Bristol), Stoyan Trilov, Sudarshan Paramesvaran

cussans_dune_dts_fibres_installation_6feb25.pptx

AFC status:

Pre-production boards delayed, discussions on-going regarding production boards 

MIB v3 status:

expected shipping on 24/01

new action: DC and ST to check current

6th Feb:

not dead yet, couple of issues (assembly time issue, DC fixed; wrong resistor value which can be fixed easily)

powers up, FPGA module powers up and visible via JTAG 

MMC: programmed to microcontroller, plugged into crate, seen by crate and has power. Issue: handle not working, probably hardware issue as looks like always on irrespective of handle being pushed in/out. ST to check if microcontroller can see it going on/off. ST noticed difference to previous crate, having to power cycle after plugging in to crate, he will investigate.

Actions:

Check pads from shockley diode to microcontroller, measure voltage on management power when plugged in, program MMC to check if it thinks front panel handle is being pulled in/out. 

Need to specify more carefully the edge finish of pcbs otherwise need to file them... 

Fix resistor values

FIB v2 status:

DA to test FIBs once DTS HSI op-mon work complete - outstanding

6th Feb:

Replaced existing FIB with one of the two new ones, programmed using bitfile fanout figuring out why I can't check status...

Action: 

probably need to program the PROM 

GIB v2 status:

GIB due by end of January   mid-feb...

DC and KC working on case for GIB

moved from end of April - moved to mid/end May (waiting for GIB to decide)

AFC:

still due... 2nd half of february

still time to include the new ones so but may need Magnus to modify old ones to look like new ones if not... 

MIB tongue2 v2

DGC waiting on PH to respond

Documentation: 

proposed document list and assigned authors:

• Electrical review followed by Electrical safety doc : DGC has made a start
• Design files : DGC
• QA/QC plans : SP
• Installation : to be removed, if current charge is accepted
• Production/procurement doc : DGC
• Intro and test doc : SP/DA to organise meeting to discuss this

 

tentative dates: Easter break begins on 18/04, aim for documentation be ready by then. implies testing finished by end of March, implies test plan available by of end of February

15:15 → 15:25 Timestamp initialisation

Speakers: David Cussans (University of Bristol), Stoyan Trilov

Discussion around epoch for DTS timestamp

 

This will be revisited after finalising work on GIB - ST suggests do whatever WR does using vanilla conversion routines 

15:25 → 15:35 DUNE DAQ v5.2.0

DTS HSI in v5.x.x
- OKS
- Op mon

timing-drunc integration
- custom FSM
- timing commands with arguments

Gaia high level support

Speakers: Diana Antic (University of Bristol), Stoyan Trilov

DA in final stages of testing DTS HSI op-mon, due to finish 24/01 - done

C++ side done

On hold:

Fix some HSI controller command to get that side working for op-mon

Then get to work on setting up dashboard in grafana (speak to Marco)

do research into grafana  

15:35 → 15:45 Nexys Video Ethernet

Speakers: Jean-Pierre Martin (Universite de Montreal (CA)), Jean-Pierre Martin (Universite de Montreal (CA))

Nexys being shipped to JPM, ZCU102 being purchased locally

Arrived at JP - check that ethernet link is unreliable, be able to rebuild bitfile and check whether the problem it's timing constraints - if done quickly, we can get onto buying/borrowing lots of Nexys video boards 

15:50 → 15:55 Operations support

NP04

NP02

ICEBERG

Shipping Timing Unit to CRP factories

Speakers: David Cussans (University of Bristol), Dennis Lindebaum (University of Bristol), Diana Antic (University of Bristol), Stoyan Trilov

NP04: 

DA and DL brought up DTS infrastructure after power-cut

NP02:

integration with TDE outstanding planned for Match 

firmware and software outstanding 

add specific item to agenda

ICEBERG:

Future of ICEBERG is uncertain put away... 

Feb 6th:

Roger Huang: debugging reports problems with middle WIB in crate - it's not responding to turn laser on nor measure round trip delay. Not timing problem yet unless make lots of APAs

CRP integration: grenoble CRT needs WR-Len which we will look for, Fermilab CRT needs 2 Charon modules, one of which will be recovered from NP04 CRT and other one we've already lent him. We have 2 FMCs from Nicolo T. so, ACTION: find enclustras for them st we have 2 more units... if Nexys issues don't get resolved. 

TDE working, bottom DE working (?), Nuno will be dragging a fibre 

 

 

 

 

15:55 → 16:00 Round table

DC: 1/2 documents 

DA: FIB testing, document draft

DC/ST: chat to summer students
