Hi Elliot,

I think that it would be very useful to get something on the physics impact of the throughput reduction is. HH->4b is a good proxy here. Even if we don't have enough time to get it in the official material for the DR, you can still have the statement available.

In the end it's the physics impact that NSF wants to see.

Thanks  -  Hal

Hi Hal,

We updated the cost and board numbers in the PEP updates I sent to Mike because of the MoU changes, but kept the same impact (i.e. we used the impact to define the cost change). That message (June 28th) was CCed to:Usatlas-hllhc-l2deputymgmt-nsf-l AT lists.bnl.gov so you should have gotten it, but if not let me know.

The hard part on the impact is what the effect of a 17% or 33% change in throughput is. Particularly because the throughput requirements have a margin in it. We could based on the TDR probably estimate what happens to HH->4b with 17% or 33% less tracking rate, which would be a proxy for what would happen to sensitive topics in general. Is a change in throughput sufficient or should I spend an hour trying to figure the impact on HH->4b (the only topic where there are enough studies to actually get a number).

Thanks Elliot!

So - just to confirm - on the scope contingency/opportunity side, the costs and/or decision dates have not changed? Also: do you have any improvements to the impact statements to suggest?

Cheers  -  Hal

Hi Hal,

The QA/QC documents are here:

6.8.1 L0 Calo:  https://atlas-hllhc.docdb.bnl.gov/cgi-bin/private/ShowDocument?docid=852

6.8.2 HTT: https://atlas-hllhc.docdb.bnl.gov/cgi-bin/private/ShowDocument?docid=849

6.8.3 Global:https://atlas-hllhc.docdb.bnl.gov/cgi-bin/private/ShowDocument?docid=851

We've checked the technical specs and nothing has changed since PDR.

There are scope/opportunity tables in the PEP do you want them copied your excel template. It seems the PEP has all the information needed, why duplicate?

Dear NSF L2s/DL2s,

Just a quick check on the status of the documents that were due last week:
  - Tech Specs update (7/1)
  - QA/QC docs - 1 per L3 (7/3)
  - Scope Contingency/Opportunity tables (7/5)

Full schedule: here

So far, I've only heard from Muons. Could the rest of you let me know where I can access your documents. I'll get started looking them over.

Thanks  -  Hal
