1. Vladimir informed about Tev-TD joint projects status, some of them have
been reviewed in the last two weeks: a) 6T dipoles to provide space for
additional separators ; b) 8 new polarity switches for separators; c)
15kV HV modulator for TEL-1; d) on-line survey system

2. Jerry was asked to address OAC(Open Access Client) situtation [the
way to process oline data from different instruments] but he redirected it
to Jean and she said that in few weeks (<1 month) the front-end FW
H-emittance will be computed with dP/P correction from the SBD.

3. Quiz of Tev projects: a) Mike M leads the A0 modification project
and has two feasible solutions for that, but its benefits are still
unclear - so, he will call a meeting of all physists involved; b) Andreas
leads IPM development and (reported by Vladimir) so far the project is
doing well, specs are almost finalized, some tests are planned and under
preparations, nevertheless its still unclear whether we can get two IMPs
installed during the next big shutdown; c) Jim Steimel calls the "final"
mtg on the tEv BPM specs next Wed, 10am in Penthouse; d) Tan has just
started tunetracker development, actively communicates with NI (worlds
fastest DSPs); e) Ron reports that two options had been considered for the
A48 collimator installation one does not give enough space for TWO
collimators, another requires two new cryo-bypasses (instead of one) and
stripes us with one H corrector.

3. Jerry: only one store last week, low luminosity (12.6e30) because of
pbar delivery problems in AA-MI during shot setup (resuklted in low
N_pbar) and protons stayed too at 150 Gev helix (--> low N_p), plus there
was a separator spark 10 min into HEP. At the end of that store we had
kicker prefire, then found ground fault at A14, warmed A sector up,
replaced ground faulted element, unroll 17 magnets with >1 mrad rolls.
Cooldown may start Saturday (then Tev will be ready for shotsetup
Tuesday -?).

4. Bruce and Vladimir reported generation of the DC beam in the Tevatron
at 150 GeV at the level of 1-3%/hr which is much less than DC beam coming
from MI (vary store-to-store from 2 to 15%). Vladimir observed that in
store #2285 when pbar injection was delayed and protons stayed 40 min at
150 (on helix) - DC beam intensity lifetime was longer than bunched beam
intensity lifetime. Bruce did dedicated studies with single p-bunch at
injection (central orbit). His data show fast (1min) escape of the protons
from widegate intensity window (11 buckets) after injection. There are
ideas for future studies (vs # bunches to coalesced, MI
coalescing-efficiency, change timing of inj-kicker, etc).

5. Vladimir also reported a) good (0.25%) agreement between SBD and FBI
intensity measurements; b) proton V emittance growth at 150 (helix) of
about 4.8+-1.5 pi/hr - observed during shotsetup #2258

6. XLZhang has shown results of the last tunescan of the proton lifetime
at 980 with gaussian beam TEL - compared to preshutdown scan (with
rectangular=flat transverse e-current distribution) the best lifetime
improved by factor of 2 (160hrs vs 70 hrs) and resonances are not that
strong (i.e., tune area with good lifetime is significantly larger, no
12th order resonances are seen). There were concerns about beam conditions
in the two scans and XL admittend some factors out of full control (some
shaving, mm-scale uncertanty in beam-beam alignment, tuneshifts due to
TEL). He thinks that now Schottky spectra observed with TEL acting on the
protons look similar to what have been calculated by Yuri.

7. Valery reported some results of optics measurements: he analyzed
differential orbit displacements after turning On/OFF some dipole
correctors and found that in order to explain the data he needs to
fudge main bus quad focusing by +0.2%, local quad correction cuircuits
F_QA0U by 1%, F_QC27 by -1.5% and F_Cq7 by +20%(!). Experimental data also
indicate that beta-functions in some locations are off by +-30% from
the model which we use for all our calculations. Coupling analysis to
follow. Mike Martens comments: a) Peter Bagley also saw beta-function
deviation from the model by as much as 60% in Marchj 2001, but he
compensated it down to 10% (error of BPM measurements) by changing Q3
stength on one side of IR. That correction was not the same at 150 and LB
and nobody understood why. Mike also mentioned that electrical offsets of
the BPMs can be as big as 1, even 2 mm and that might affect Valery's
analysis. Investigation to follow.

8. Alvin analyzed beam distrubution vs longitudinal action at 150 GeV,
found that it's far from Gaussian or parabolic, it's closer to 1-(I/I_0).
Some dip in the center of the separatrix is also seen. He plans to study
evolution of the longitudinal distribution vs time at 150.
