Abstract:

A peaked, record luminosity of $4. 2\, 10^{31}$ has been reached at the
Fermilab $p - \bar{p}$ collider. The lifetime of this luminosity at the
beginning of the store is about 9 to 10 hours. This lifetime can be explained
based on the anticipated loss of antiprotons and protons due to collisions and
emittance growths. We report on transverse emittance growth rates based on our
Synchrotron Light Monitor. Longitudinal emittance measurements are based on
the TeV Sample Bunch Display data. It is shown that Intra Beam Scattering is a
significant source of emittance growth. We comment on other possible factors
for these observed emittance growth rates. Finally, we comment on future
luminosity lifetimes, as we hope to further increase our peaked luminosity.
