History and PRESENT STATUS of ME Program at BNL

1) Comments are my own--no official statements from BSA Management.

2) ME experiments are defined as those funded or proposed by ME contract scientists. Definiton of ME is thus time-dependent.

3) ME experiments have a history at the Cosmotron and AGS dating back to 1956 ! The Cosmotron program and the subsequent advent of LAMPF stimulated the creation of ME program office of DOE. AGS involvement has been virtually exclusively nuclear strangeness-related and the first proposal goes back to 1978. Experiments continued without interruption until 1998 with the termination of the fixed-target AGS operation funded by HEP.

4) Until 1999, the position of DOE, as stated first by Dave Hendry, and reiterated by Dennis Kovar, was no DOE nuclear-funded fixed target AGS operation. This was EMPHATICALLY relayed to me by T. Kirk.

5) At the 1999 User Meeting, after some input from colleagues from USA and Japan, that categorical statement was modified to so as to allow continuation of E930 (hypernuclear gamma rays) and E931 (weak decay) in FY 2001, using beam available during E949 set-up.

6) BNL management has been discussing funding for a ME program for spin physics experiments at RHIC. This includes pp2pp (elastic scattering). The ME group is to be restructured to allow this.

7) In a parallel effort, lobbying for nuclear strangeness continues along with proposals for baryon spectroscopy and Ke3 decay using the Crystal Ball. There also appears to be considerable support for continued experiments in the S=-2 sector.

8) NSF support now appears to be imminent for other rare decay experiments like MECO. Many groups participating there have DOE ME funding.

9) In view of 7) and 8), the possibility for AGS fixed-target experiments in the future cannot be ruled out absolutely. The advent of JHF would strengthen the role of AGS as a bridge to JHF. The time frame for such experiments is from FY 2002 forward.

10) BSA management does not appear to present a united front concerning the fixed-target nuclear program. There are mixed signals sent to Washington.

11) There will be at least 3 new proposals and at least one LOI relevant to ME presented at the next PAC meeting.
