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

[John Parsons <parsons AT nevis.columbia.edu>]

Hi all,

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

                        John

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?
