Hello spinners--I thought that we had a very good meeting
Dec. 17.  

On our schedule
---------------
First, it is clearly too soon to have a 1st draft
ready by Jan. 7.  I would like to change the date one
week, to Jan. 14.

I propose that we keep the planned telephone meeting
Jan. 7, 1700 EST, to discuss issues that we still need
to resolve, and progress on the draft.  (If this time is
a problem, please send to me.)  

We have already planned to have a collaboration meeting 
on Jan. 14, and I suggest that we keep that date.

I will look into changing the due date for the report.
With the delay of RHIC, it would be very helpful if we
can shift this to the end of February.  For the moment,
I suggest that we shift our dates one week--2nd draft
Jan. 21, discuss, then to collaborations; final draft
to administration and for DOE advice Jan. 27; completed
document probably 1 week later.

On the format
-------------
Werner and I weren't satisfied with the 2 column approach,
and we have sent to Yuji the outline in a 1 column format.
It should be on the spin discussion page soon.  Please use
this template for your drafting.

I have also thought about the length of the report.  The preview
article on RHIC spin in Annual Review of Nuclear and Particle
Science, 2000, was 50 pages, and I believe that it went into
the physics at the necessary depth.  We will cover the same
topics, with new work, results and plans.  We can also refer 
to it and to other existing articles.  Therefore, I suggest 
that we try for that level of detail of presentation.

Notes on Dec. 17 meeting
------------------------

1. Report from Wolfram and Mei on L,P plans.  Their information
on the web covers what we need.  Development will continue to be
folded with spin physics running, probably weekdays.  We agreed 
that 3 time sequences should be considered: 
a) 3+10 weeks per year (3 setup, 10 physics),
b) 3+10 weeks every 2 years, 
and c) 3+5 weeks per year.

For a), the maximum luminosity projection is 340 pb^-1 thru 2008.
For c), the maximum L projected is 90 pb^-1.
P=0.65 to 0.75 by 2007.

The L considers 2 IPs only.  (But note that Brahms expects to complete
its spin running in 2005.)

For 250 GeV beams, multiply luminosity by 2.5.

2. Bernd reported on the STAR upgrades.  Main spin upgrades are the
forward calorimeter (photon, pi^0, +jet, probe lower x), proposed
to NSF ($0.8M), to install for 2007 run; endcap tracker for W charge
sign.  The W tracker is stage 2 of the STAR tracking upgrade, for
eta 1-2.  It is to be proposed after the FY06 run, to install for the
FY10 run.  (The timing is related to ongoing GEM R&D, and desire for
a demonstration of polarized beam at 250 GeV.)  Ball park cost estimate
is $4M without contingency and overhead.

A "stage 1" upgrade of the inner tracking in STAR, driven by the
heavy ion community, will improve heavy flavor tagging capabilities,
enhancing the spin program.  The forward calorimeter upgrade is 
mainly driven by the measurement of gluon saturation.

3. Matthias reported on PHENIX upgrades.  Main spin upgrades are the
vertex tracker for photon+jet and heavy quarks, and muon trigger for W.
The barrel silicon tracker is proposed to be ready for the 2008 run,
cost $7.3M ($4.3M requested from DOE and $3M from RIKEN).
The muon trigger proposal to NSF will be submitted in January, cost $1.8M.
There is a separate, necessary, upgrade for the muon tracking system
electronics, at $1M (JSPS Grant application).
The muon trigger components are to be ready for the 2008 run.

Both Star and Phenix have other upgrade projects which will benefit spin.
A major issue in our report will be to identify the "spin" upgrades,
and their contributions to the program.

4. Discussion on sensitivity goals.  This discussion was not completed.
Bernd presented a simulation showing sensitivities for W physics using
two luminosities (see web).  Werner presented a figure with P=0.5, 
L=100 pb^-1, for the Phenix acceptance (see Figure in outline for report).
We still need to agree on goals, and both collaborations are discussing
this issue.

5. A strawman spin plan is on the web.  This shows 200 GeV thru 2008,
then moving to 500 GeV.  Studies on 250 GeV beams start in 2005.  The
maximum delivered luminosity is 340 pb^-1 thru 2008.

6. Outline of document and writing assignments.  This is on the web.
If you don't want to/can't do the assignment, email me!  Also, if you
are not listed and want to be, email me!!

Thanks, and have a happy holiday!
