U.S. ATLAS HL-LHC Upgrade LAr Level 2 and Level 3 Managers Mailing List

[Tim Andeen <tandeen AT utexas.edu>]

Hi Hong, 

I made some comments directly on the word doc and ppt slides and uploaded them to the indico page: 

L3-LAr_6.4.5_Scrubbing_May2022_V2_TAcomments.pptx

LArBOE_PAshaper-May2022_V2_TAcomments.docx. 

My main concern is that there seems to be an inconsistency in the BOE text and the example drill down (at least in the version that you uploaded). Related ,the packaging costs in the BOE don’t match the tables or slides, and I couldn’t see how you got $29k for preproduction and $86k for production. Also the cost estimate table in the BOE material costs don’t match your slide 2 table. Are they supposed to? 

Best, Tim

Here are my comments on Hao's slides and BOE.

Slide 2: This is the total cost _after_ BCP 069?
Why BNL_P_3_AP2 BNL Professional 3 so high in FY24?
What is BCP 075 for?

Slide 3: What is the effect on this WBS from the COVID BCP?
The BE crate setup will be built at CERN, but by who? BNL still? The
BOE still says "The backend test stand will be built to perform the
integration test of the BE electronics...".
Has the BOE just not been updated??
I still don't know what BCP 075 will do.

Slide 5: The first table is too fuzzy to read.
That fuzzy table seems to include 17k for "software", but isn't that
already in the second table? What is the software?

For the BOE:
I don't understand why it talks about "test board manufacturing
costs". The slides indicate that we're just buying dev boards. Are we
building any boards in this WBS??
Since the majority of the cost of this WBS is labor, and it's based on
phase I (and earlier) experience, could we not have an attachment
detailing the phase I labor? In general, it's not very clear exactly
what each person is working on and when for this WBS.

Hi all,

         We will meet Friday at our usual time.  The indico page is at

https://urldefense.proofpoint.com/v2/url?u=https-3A__indico.bnl.gov_event_15546_&d=DwICAg&c=slrrB7dE8n7gBJbeO0g-IQ&r=y4qQBOsjsdgJNx-_8SvpS9786vHE4GOddPXp1ozJgWc&m=KYta6_jQMkuN6xO_qteMf60cetz0s9eRiWRDMinw9G7jS8gX-Qfwc5nmfe1tMV4S&s=rfZFGpknDud1G2UHzzVvYgCd4ZZlmW66i3DjfVPF5k8&e= .  In addition to the usual

roundtable, we will discuss preparations for the DOE RLS scrubbing that

will happen next Wed. (see https://urldefense.proofpoint.com/v2/url?u=https-3A__indico.bnl.gov_event_15406_&d=DwICAg&c=slrrB7dE8n7gBJbeO0g-IQ&r=y4qQBOsjsdgJNx-_8SvpS9786vHE4GOddPXp1ozJgWc&m=KYta6_jQMkuN6xO_qteMf60cetz0s9eRiWRDMinw9G7jS8gX-Qfwc5nmfe1tMV4S&s=8ExQigeuYbHqw5bcu5I5m24XJ2AX6W8MCu07aY4C_eg&e= ).

        Before Friday's meeting, Hong and Hao should upload to Friday's Indico

their relevant documents for the scrubbing.  We will look at them

briefly together on Friday. Then, to help with the DOE scrubbing

preparations, I would like to ask Tim to read over Hong's PA/S

documents, and Andy to read over Hao's System Integration documents, and

to provide feedback latest by noon on Tues. May 3.  I will also go over

both sets of documents.  That should give Hong and Hao some time to

incorporate any changes before the scrubbing with the PO on Wed. May 4.

        Another issue: during our weekly meeting on Apr. 8, we went over any RR

changes to be made as part of the quarterly RR review. I need now to

collect all the final changes and propagate them to the PO. Please make

sure the RR version you uploaded to the Apr. 8 Indico reflects all the

changes to be made to your L3, updated as necessary following the

discussions we had.

        Regards,

                John
