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

[Tim Andeen <tandeen AT utexas.edu>]

Hi John, 

I also updated the FEE traceability table and BOE. This reminded me that the ADC production cost ($708k) includes the packaging cost. A part of the BOE that is not updated is the switch to the BGA package, and of course we don’t have quotes for this but actual costs now. At this point I want to leave it as it is and update for the NSF review. But if anyone asks this will give them something to write about in the report. 

Best, Tim

Hi John, 

Thanks, I took your suggestions and made the changes (and fixed a few more typos). It’s in docdb, I guess  we email Rhoumela to fix the links? I also took a quick look at your slides. 

On your L2 slides: 

p13 - **/21 in second to last bullet looks like a place holder? 

On your L3 slides: 

p14 - could add when LSB2s arrive at Columbia, when FEB2s are delivered to CERN 

p16 - could add names of Columbia/Pitt ESH people (my sides have Kathleen Crowley, https://research.columbia.edu/content/environmental-health-safety for Columbia)

Hi all,

I looked over the various talks for the DR, and they are all in good
shape.  I give some comments/suggestions below.

pp. 6-7 - these numbers have not changed, so you should just flash them
to have time to focus on changes

p. 8 - COLUTA does not meet the "<100 mW per channel" spec, which at FDR
was agreed to be changed (but I don't know if we formally changed it).
For now, just delete this spec. from the slide
  - since you mention the downlink speed, maybe add the 10.24 Gbps
uplink speed?

p. 9 - some variation in font size in table; is this intentional?

p. 16 - BER limit should be 10^-17 (not 10^17)

p. 17 (or somewhere) - add that first preprod. wafers just arrived at CERN?

p. 20 - you mention "testing 80 prototypes from MPW run", but we have
only tested ~20 so far (in QFN).  Maybe change this to the plan to test
150 or so in BGA from extra dice ordered?

p. 23 - add that can soon retire risk of additional ADC iteration, once
BGA is validated

p. 24 - "... and the LAr Phase 1 upgrade." (ie. not Trigger

p. 7 - why do you have "ATLAS FDR and PRR ?"  (you do not need that)

p. 9 - change to "Will submit PCB for sRTM v2 in March 2023"
  - also include previous and new numbers of boards

p. 15...  - still need to be completed



Hong
-----
p. 1 - some formatting issues on our names...

p. 3 - in my version of this slide for other reviews, I highlight the
last bullet of each in a different color to stress both DOE L4s are
"critical"

p. 4 - put a box around the DOE scope?
