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

AFC status:

Creotech responded, now to decide what to do as even pre-PRR takes 16 weeks, production 24 weeks; 

Status: waiting on Jim to see if we can afford this as there's no official budget for pre/actual PRR 

Happy to use Bristol modified AFC v4 boards for PRR 

Magnus can continue doing modifications to AFC v4 - if not done by mid of next week, DC to chase
Action: arrange internal review of DUNE mods to AFC v4

MIB v3 status:

ST: during MIB review number of pins was considered; FPGA has enough but other module doesn't ie must swap from internal to external termination; can get 10 links to CC pins 

Action: 

DC: email Pete Hastings to get quote 

A. Thea suggests getting more expensive option if faster

Note: don't forget MIB tongue 2 

Fib v2 status:

waiting on Magnus and OKS HSI to be done so ST can work on this

Gib v2 status:

Action: JP made list of suggested changes, DC to look over this soon and arrange for internal review of gib

Documentation: 

Action: Electrical Safety documentation - draft by early December 

15:15 → 15:25 Timestamp initialisation

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

ST: after release,

1. should get back to this after fib v2 

2. then timestamp full change

3. then timestamp with TAI 

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

HSI: 

Diana: Working on testing HSIReadout using drunc on hardware (Boreas on fmc) 

Action: ST + DA to work together on getting this working

Opmon:

Action: After OKS stuff working, ST, DA and Marco Roda to meet to talk about getting Opmon back 

Timing-drunc integration:

FSM is now configurable st we can request FSM for ourselves and we won't need to use enable triggers and other commands that we don't need

Custom commands which take args; ST tested a couple weeks ago and works - implemented cmd to send timing msg 

Action: to add rest of commands after this release 

Gaia high level support: 

ST: there's a param to decide which timestamp source you're using (implemented) and the other is to decide which IRIG source to config IRIG epoch you want (to be done for next release)

15:35 → 15:40 DTS service software

Speaker: Stoyan Trilov

ST: Pierre and ST discussed this 

After release, to discuss plan with Pierre 

For PRR should have design for this (UML diagram)

 

15:40 → 15:50 Phase measurement functionality / Endpoint on Ultrascale+ fabric

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

ZCU102 : to test before getting it to JPM

Action: DA to check if SFP interface on ZCU works 

JPM: to use his branch to test this ^ - v simple EPT with 4 resistors 

 

 

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: 

Done.

DL: to make list of what went well/not while writing up diss - 2 weeks to get draft done 

Action: all of us to have a think and catch up in 2 weeks on this ^ 

NP02:

Action: DC to figure out if support we currently have (Aaron, Wes) will be enough/around for NP02 run

No beam until March... 

Dario pushed back WR integration to end of year... 

ICEBERG:

No news (good news?) - DC to check if fans are working  

Everyone at fermi had to take August off... 

Shipping Timing Unit to CRP factories: 

Action: DA to do after HSI work, to fix cables and lid etc... 

 

 

15:55 → 16:00 Round table
