1. Dept news: a) Ron took part in RHIC retreat - RHIC has very frequent
quenches, including on the DC beam in abort gap, their collimation system
is not very efficient and "touchy", integrated luminosity goals are not
met, etc; b) Jim Steimel presented Tev expert opinion on the Tev BPM specs
- recently reviewed - there is desire to see pbars (though not
simulteneously with protons), make new BPMs compatible with current
BL(oss)M(onitors) hard-and software; c) Jerry chaired F0 Lambertson
liner review and so far everything looks OK, installation of prototype
liner in a spare magnet at MI-60 seems to be critical for the assurance.

2. XioaLong overviewed 8 stores we had since last Fri - luminosity varied
between 26 and 32e30 (except #2705 with L=22 when QFA4 was found to be
corrupted ealy in squeeze and we lost 30% of pbars there), effective
emittances are OK, lumi is low just because of # of protons and pbars at
LB, extensive maintanance studies led to significant improvements since
last week - summaruzing what Jerry, Bruce, Vladimir, Dean, Jean and
Xiaolong said: a) emittances at injection fluctuate store-to-store,
especially proton (V between 25 and 35 pi) tat affects lifetime
afterwards; b) lifetime at 150 is much better now thanks to orbit
smoothing, better decoupling on both helices and slight drop of hor
chromaticity; c) no significant ramp efficincy improvment is seen after
stadies, we coped with significant differences between helices and central
orbit , significant time is needed to make futher improvements; d)  pbar
losses in squeeze are significantly reduced - thanks to orbit smoothing
and fixing tune excursions; e) proton hor emittance lifetime, proton
intensity lifetime were significantly improved by lowering hor tune by
0.002, as the result the luminosity lifetime is almost back to preshutdown
value 10-13 hrs vs 8-9 hrs week ago.

3. Dave Johnson proposed to roll two quads in P1 line by about 2 mrad in
order to improve vertical dispersion match between the line and the
Tevatron, that should lead to 4-10 pi reduction of vert p-emittance. His
estimate that it will not take more than 3 shifts (less than a shift in
the tunnel) - even in the worst case scenario.  To many of us that seems
to be a reasonable thing to do before Aug shutdown.

4.  Valery is half way thru last week lattice measurement data analysis:
he sees lattice perturbations at A46 and C46, some deviations at A sector;
he confirmes that separators are (were) doing well (all properly connected
and producing right kicks).

5. Yuri pointed out that with existing helix (and any other helix
considered so far) it is hard to decouple because S3,S5,S7 coupling
correction families have approximately the same phase in the driving
resonance term, moreover, S1, S2, S4 feeddown sextupoles, SF and SD
families have the same phase. Only S6 family is somehwat out of
phase, but not orthogonal (that explins why we are forced to run
high 20A current in it). His question/request is - are there unused
sextupoles or can we install few new sextupoles orthogonal to S3? (to
investigate)

6. Andreas calibrated chromaticities extracted from E17 Schottky spectra
at the E(nd)o(f)S(tore) and found a remarkable agreement :
C_schottky=Slope*C_measured+Offset, where slope is about 0.9 in V and 0.86
in H plane, offset =0 in H plane, due to various errors offset was large
(6 units) in V plane.

7. Vladimir analyzed new Schottky spectra in store #2692 and pointed out
that after recent improvement of the detector electronics spectra look
quite clean, errors in tune determination less than 0.001, and less that
1-2 units in chromaticity. Values of chromaticities now look realistic.
He calls for having the Schottky detector continuously running on the ramp
for the C_v,h measurements.

8. At the EoS, XL observed that the abort gap losses (C:B0PAGC)
anticorrelate with vertical chromaticity changes - as the TEL cleaning
physics model predicts. He hezitated to draw final conclusion because
C_v also affected losses from bunches.

9. Andreas and XL did remove pbars at the EoS with a verical collimator in
an attempt to determine emittances. Though they were unable to separate
tunes enough to claim pure 1-D shaving, the discrepancy in
different emittance measurement data is striking: V pbar emittance from
SL was about 40pi, about 28 pi from FWs and 10-15 pi from scraping.

10. Alvin warned us of using FBI intensity monitors - they are upto 15%
miscalibrated, show strange things during cogging, etc. He thinks we
should use SBDP(A)IS channels in our summary tables and for the MCR
"comfort plots". He also pointed out that Schottky power of proton beam
goes up when we open helix and that probably affects what we called
"longitudinal shaving". When comparing average "good" store (with avg
L_peak=40.3e30 - back late April early May) and recent "bad" stores
(28e30), he sees that effective emittances are about the same (23-24 pi),
hit on number of protons is about 10% (7770e9 vs 7020e9), and about 35% on
pbars (885e9 vs 650e9). Lumi lifetime was pretty shot recently (9 hrs vs
12.2 in good stores, due to proton losses).
