1. Vladimir a) presented "thank you" Letter to Gennady Kuznetsov - Guset
Engineer who designed the TEL, Gennady goes back to Russia in April.
b) announced that 5 TeV people are moving to BTW from Linac and
X-Galleries

2. Mike Martens overviewed the Tev week: 4 stores since last Friday, two
with L about 20e30 (shoot from small stack), 2 with 29-31e30. Problems
with collimators seem to be fixed and CDF losses are reduced, dampers did
not work properly in one store (Tan reports that this is due to larger
than usual coupling rather than dampers itself). Lifetime at 150 is not
that good as a week ago.

3. Dean explained the problems we had with collimators: a) during the
shutdown the current which drives the collimator motors was reduced from
5A to 3A in order to reduce noise in cables (noise sometimes interfered
with collimator motion by inducing false "stop" signals for limit
switches); b) because of that, many collimators did not always move while
the we though they're moving, as the result collimators were not aligned
to the beam or were sometimes left too close to the beam so when they
start to move they go into beam and we quench on losses; c) all that is
now fixed - currents restored back to 5A, RC filters are installed on the
signal cables in order to reduce the noise when the motors operate,
collimators realigned and recalibrated wrt LVDTs.

4. XL scaled helix size at the EOS 2328 and observed that a) p and pbar
lifetime is better at 80% (smaller) helix; b) effective emittance stayed
constant 33pi when helix was reduced from 110% to 70%, then B0 emittance
went down 2pi when helix reduced to 46%, while D0 eff-emittance went up
1pi til 50% amd then down 2pi below 50%; c) contrary to eff-emittance,
p-SyncLite emittances did grow from 36 pi to 44pi (again, when the helix
was cslaed from 110% to 46%), Pbar Vert grown 4pi from 32 to 36pi, Pbar
hor reduced from 33 to 30; d) emittances measured by FWs varied the same
way as Sl emittances, but changes were 3 times smaller, e.g.  only 2-3 pi
in proton emittances; e) during helix changes from 110% to 46% proton
tunes were constant within 0.001, while pbar tunes varied by 0.003-0.004
(one tune went up, anotther down).

5. Vladimir analyzed data on p and pbar beam centroid postions vs helix
size and found significant miscalibration in HE11A, and 10-20% error (vs
helix model) in VE11P and HE17P and A. >30% error (again, wrt the Tev
lattice and helix model) also found in proton vert and pbar hor positions
reported by SyncLite.

6. Stephen and Harry tried to measure DC beam intensity in the abort gap
(timed Fws and SLite, respectively). When TEl was turned OFF at the EOS,
some 6e9 proton were accumlated in the DC beam but both FWs and SL
did not see it. Later, an RF station trip oocured and 36e9 protons went
into the DC beam - and SL was able to see that. Stephen gives up
on FWs as the DC beam monitor. More work is planned with SLite in order to
improve signal to noise ratio for the DC beam.

7. Yuri and MikeM made the first attempt to run with so called "5 star"
injection helix (whicj employs 5 separatos vs 3 in current "new-new
helix") and found it's not worse than "new-new" one, also no big feeddown
sextupole changes wouyld be needed for it. They sucessfully ramped beam on
the 5-star helix. More work needed to adjust injection orbits at A0 anf F0
where losses are seen with 5* helix.

8. Bruce scanned aperture at A0 and found it is not much smaller than
expected. Some additional aperture can be gained by moving orbit at the
A0 beam dump (or move the dump).

9. Jim S shown modified schametics of the E17 Schottky electronics
(filters added), now results are quite promising, we have TV monitor to
see the Schottky spectrum traces (Ch20) and McGinnis wrote software to get
traces in ASCII format (T122).
