[DIRC] Fwd: EIC Detector R&D update

[Pawel Nadel-Turonski]

Hello Everyone,

I am forwarding the final report of the committee from the detector R&D.

Unfortunately, it seems that the committee did not look at the proposal 
to remind themselves of why high-pT physics, and thus momentum coverage 
for PID, is important for the EIC program. It seems that we will have to 
make sure to remind them at every opportunity. It was a clear oversight 
on my part, but one that should be easy to address. Clearly, the FDIRC 
as proposed for the SuperB would not be sufficient to cover the 
requirements.

Regarding comprehensive background simulations, I communicated in 
private during dinner to our reviewer that Mike Sullivan is trying to 
use the SLAC simulation package to set up a synchroton background 
simulation that will include all the elements in the ring, not only +/- 
X m around the IP, but this effort requires some further work on the 
lattice before we have the final results. Since it did not make it into 
the report, we will have to be more explicit about these plans in the 
proposal update.

The other comments (on page 8), seem to indicate some other minor 
misunderstandings - for instance, we never claimed to have done 
simulations with SiPMs - but in general seem to be very much in line 
with what was presented. We will clearly have to reiterate our plans for 
pursuing both a lens-based internal solution and a mirror-based external 
one. There are also some more specific questions about timing 
resolution, reconstruction algorithms in wide bars, dealing with 
multiple hits, and motherboards for the MaPMTs that will require more 
specific answers. Perhaps we could try to come up with some of the 
answers for our next meeting?

Cheers,

     Pawel

Dear EIC Detector R&D PIs,

Attached is the report from the Advisory Committee meeting this past 
December.  The updates and progress reports presented at the meeting 
were extremely helpful.  In addition to the Committee's comments on 
individual presentations, the report contains some important general 
remarks on the program:

  * The work on Monte Carlo simulation has reached a level of maturity
    and importance at which the Labs and funding agency need to plan
    support for a long-term effort of sustained code maintenance and
    sharing.
  * There is a common interest in GEM technology for tracking and
    particle identification, in light of which we need to stay in touch
    with advances in the broad community of nuclear and particle physics.
  * The Committee emphasizes a continued focus on specific performance
    requirements for "golden measurements" at an EIC, with machine and
    IR parameters given by the BNL and JLab accelerator groups.

The next meeting of the Advisory Committee is being planned for the May 
timeframe.  The exact dates will be announced soon.  A call for new and 
updated proposals to be considered at this meeting has been placed on 
the website: https://wiki.bnl.gov/conferences/index.php/EIC_R%25D 
<https://wiki.bnl.gov/conferences/index.php/EIC_R%25D>

Please note that the due date for these proposals is April 19, 2013.  In 
the meantime, progress reports through the quarter ending March 30 from 
the on-going projects will be appreciated.

Best regards to all,

Tom Ludlam
