Dear Flemming,
It is unfortunate that the (very) provisional draft for the RBUP is transmitted during a weekend, normally not considered working hours, and with submission deadline on firstcoming monday. That does not leave much time for the collaborations comments or reflexion.
I have however taken the time to peruse the forwarded draft. I will separately forward to you my more detailed comments on wording etc.,as time allows.
Here, I wish, however, to raise the central issue of BRAHMS priorities for run 3.
In my opinion the main priorities are:
1) as much Au+Au as we can get, for -supplementing missing settings for the hadronic survey
- focus on selected high statistics measurements ( high pt, HBT, coalescence, decays etc...)
2) decent p+p data at forward angles as refenence for the Au+Au.
In my mind, the d+Au, although 'a la mode' and favored by PHENIX and STAR is NOT our main 2nd priority. Of course we shall take data, if
that is the RHIC decision, but more useful for the ongoing physics is the 'elementary' reference spectra at all rapidities, notably the forward.
I hold the opinion that a 3 beam species program is not avisable, as development overhead is prohibitive.
I hope that the collaboration will have time and occasion to contribute to this discussion.
cheers
JJ

Subject: Rhic Beam Use proposal
Dear Collaborator,
As discussed at the collaboration meeting in May, and also in an e-mail a while before QM the Beam Use proposal for
run-3 (FY2003) has to be submitted by Monday afternoon at 4.30 pm Due to QM02 and my subsequent vacation the first draft has not been available before. I have had very little input from, the previous mailings that outlined the intended beam Use proposal, so the draft attached
to this e-mail should follows that outline. Some details i.e. required Luminosities still have to be worked out , and will be done so over the weekend.
It is my intention to prepare a next draft by Sunday, but all comments received before Monday noon EDT will be duely considered.
I think the draft has about the right overall length; I will in particular be glad to receive suggested rewording of text, paragraphs,
input to the physics justifcations. The real battelewill be during the PAC meeting on August 26 since the requests
from the experiments are not very likely to overlap very well.
We have in CDR as well as in previous RBUPs always mention the desire to measure clusters (d,t and heavier) but have never given
a real estimate for what is needed. I think if we are to keep this we should evaluate if this can be done within the ~7 weeks of Au-Au
running with at most 7*35 microb(-1)
best regards
Flemming
