1. Dept news: shutdown projects - F0 liner: review next Thur (chaired by
Jerry), vacuum - ?? (chaired by Jim Volk), alignment - sometime before
July 7 (organized by Ray, chaired by ??). Among possible additional
projects: a)  second stripline 90 deg from BLT stripline (for Vahid); b)
break/rewire octupole curcuits (for Peter).

2. XL reviewed 7 stores since last Friday, all with lumi around 30e30 or
below (i.e low), effective emittance is OK. We a bit recovered in
N_protons (now around 7000-7200e9 at LB, but still low on pbar side. Major
issues: a) poor p and pbar lifetime at 150, lifetimes vary after each
cogging; b) significantly higher pbar loss on ramp (sometimes upto 15% vs
7-8% month ago); c) some 5% loss of pbars at seq13-15 of the LB squeeze;
d) reduced luminosity lifetime (8-9 hrs vs 11-12 hrs month ago) - mostly
due to faster proton H-emittance growth and poor proton lifetime.
	There was lengthy discussion why things go wrong, XL and Vladimir
offered several ideas in three categories: I. beam-beam separation is too
small, e.g.  due to: some separator plates are not connected to PSs,
lattice is screwed up by smth (e.g. S6 circuits, wrong polarity PSs),
emittances at inj are larger than they appear (= FWs lie?); II.
diffusion is too fast: poor vacuum, both beams are unstable (shaken by
what?), external noise (flaky dipole corrector PS, main dipole field
jitter, etc), electron cloud, larger - than before - nonlinearities,
orbits much closer to DA; III.  "chemistry"- includes unpredictable things
like something died after power outages two weeks ago, temperature drifts
(of what?).
	Jerry mentioned that hor Shottky power in stores is too low
(tuneline is not seen).  Bob Webber saw strange unexplainable 1/2 mm
h-orbit excursions during pbar injection. Bruce did not observe any
lifetime changes after cogging with 12 p bunches only in the machine.

Later we discussed studies we can do for the maintenance:
1. Smooth orbit (with new bumps?) today (Mike Martens+others)
2. lower C_v,h (Dean+)
3. S6 feeddowns, C46 circiuts check (Jerry +)
4. Lifetime @150GeV (Ludovic+Valery)
5. N_p and Emm_p Lifetime vs tune @980GeV   (Vladimir)
6. Scrape beam @MI and inject: lifetime & Emittance growth inm Tev (Bruce)
7. New schottky commissioning, T122 (Andreas+)
8. SyncLite @Squeeze: increase data refresh rate in one of stores (XL)
9. see ORBITH, V fluctuations at 150 GeV (XL)

3. Following last week's "discovery" of huge tune changes vs orbit
at C46 tune, Jerry and Peter zeroed current in S6 cuircuit and observed
better lifetime, but later were unable to decouple on both helices
simultaneously.

4. Yuri reported that aperture scan is complete in both planes over the
whole ring. 10 locations were identified where "central orbit" goes
way off aperture center (like -5 mm in VB49, He48, etc). With S6 circuit
current =0, detuning at C46 is reduced by factor of 10, but another
"sensistive" location found at HA11 dQ=0.024 over 16 mm (!).

5. XL and Tan tried to measure tunes at EoS by tickling pbars vertically:
seems that proton tunes are at Q_h=0.591, Q_v=0.577 (the first one is a
bit too high, the latter - too low). Conclusions are not solid :
H-spectrum was always noisy, vertical contains 4 lines. Seems that Q_h (or
Q_v?) line for pbars is just 0.002-0.003 above 4/7=0.5714. XL calls for
immidiate (re)commissioning of new Schottkies - to better see all 4 tunes.

6. Andreas and XL scaled helix (from 1001% to some 50%) at EoS in order to
see movement of FW and SL beam centroids (and thus, check that
helices/lattice are or are not different from march'03 when we did similar
msmnts). Conclusions: a) E17 FW seems OK; b) scaling problem in E11 FW;
c) hor FWs still have wrong sign. In general - no proof of problems with
helix.

7. Bob Webber and Warren S. found some saturation effects in VA16 and
HA17 BPMs equipped with digital reciever Echotek cards and fixed that. Bob
estimated single bunch BPM resolution of about 20 microns. The see (and
that agrees with Crystal BPMs) a) some strange 40-sec long 1/2 mm orbit
excursions at 150 Helix; c) 0.4 mm excursions while injecting pbars -
probably due to field in the lambertson notch (can be compensated); d) no
bad effects on orbit while cogging; e) 0.4 mm orbit change right before
ramp (when we increase chromaticities); f) 0.1-0.2 mm orbit variation in
HEP store. Valery asked can other two pickups 90 deg from A16,17 be
equipped with same cards - and after some discussion it was decided that
A18,A19 can be used for that.

8. Vic Scarpine has shown really impressive pictures of sum signal from
the BLT stripline - one can see energy or RF phase injection errors, can
see substructure in the coalesced proton bunches, etc. Andreas mentioned
that from what they see one can conclude that energy difference
between MI and Tev is not the same for proton and pbar injections
(difference 20-40 MeV). Vic thinks that in a week or two we'll have the
instrument operational in MCR.

9. Finally, Vahid shared his ideas how to improve head-tail chromaticity
measurement technique and tried to get an input from the audience on how
to get not only position but angle information from the same stripline ...
but failed, because the audience was tired of 2 1/2 hour meeting.
