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

[Tim Andeen <tandeen AT utexas.edu>]

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?
