Attending: Perry Anthony, Armen Apyan, Don Crabb 

Note: meeting was changed back to Monday, and Peter, Steve, and
others did not notice. So, these minutes reflect what would have
been said, if everyone had phoned in.

Beam Line: work on dump line is proceding. Bend angle will be
fixed at around 7 deg., using 3 coils in each magnet. C37 will
be moved down-beam to accomdate this. A 3-deg. bend magnet will
be used for the sweep magnet: it will be supplid by the Q38
power and water. Manpower may become available in June to 
start examining the current dump magnet coils (to see how many
are good) and possibly start winding new ones. Ray Arnold
has narly finished the design for the spent electron detectors
(connected with vacuum chamber modifications needed). It has
pretty much been decided to put Ion Cherenkov, and SEQ
detectors in ESA (on E158 detector cart), rather than in beam
dump east tunnel. It was decided to make a new collimator
betwen D1 and D2, rathr than try to modify the existing 3DC2
collimator (too radioactive and bigger than we need). The
pin-cushion detector will be part of this new collimator, which
must be easy to align precisely.

Compton Polarimeter: Don plus student making progress on O16
target. Peter needs to compare to Fe to see how big improvement
would be.

E160 spectrometer: TOSCA 3D field maps now availalbe for 1.4,
1.8, and 2.2 m long wedges in D3, either narrow or wide. 
Mermaid 3D model now also availalbe: gives about 5% higher
than TOSCA. Both give higher fields that used in previous
simulations: this will help the momentum resolution. Peter's
studies so far indicate a preferance for the 1.4 m long wedge,
with about 3 m of upstream graphite or equivalent. The
simulations suggest a slightly changed detector geometry,
but basically same as in January. Simulation with full field
map indicates y detector resolution need not be great, as
bending in y direction is comparable to multiple scattring.
Resolution of 3% in J/psi mass should be possible.

E160 detectors: Steve Guertin (UCLA) working on qustion of
what granularity is needed.

E161: Peter gave talk at QCD workshop at UVa. Questions raised
on thoretical interpretation. COMPASS will run this year for
3 months: hope to get real data. Target getting record high
deutron polarization (60% or so). They had hoped to run 6 to 9 months,
but cut back due to LHC cost ovr-runs. RHIC is on track to measuree
Dlta G by 2004 pretty well.

Citizen Committees: there was a HEEK review May 6: they detrmined
that there are "no issues" for E160. John Weisend made the
presentation.

Collaboration Meeting: will be June 3. Need near-final design
for E160 componants. Who will come, who will give talks?
Peter sent out announcement and asked for speakers.
