Hi Kathy,
   Here is a draft introduction... feel free to edit or add to
it as you see fit.
   cheers,

The year 2003 has been both a challenging one and a productive one
for the Hall A collaboration. Challenges included the several 
schedule shifts due to delays with the delivery of the septum 
magnets, the discovery during a running experiment that the 
first septum had been delivered to us by the vendor mis-wired,
and the additional schedule delay due to the consequences of 
Hurricane Isabel. Despite these challenges, the year was a fruitful
one, whether measured in terms of refereed publications appearing
or being accepted for publication, talks and conference proceedings,
PhD theses produced, or detector developments for upcoming
experiments. \\

After experiments E00-007 (Gilman, Holt, Meziani) and E01-020
(Boeglin, Jones, Klein, Ulmer, Voutier) were completed in October and
November of 2002, the Hall A was down for the installation of the
polarized $^3$He target. Starting in early January 2003 the
measurement of spin-duality in $^3$He (E01-012: Chen, Choi, Liyanage)
successfully took data. After the run was completed, the first
of the two septa magnets was installed, and the polarized $^3$He
target was moved 80 cm upstream to the septum interaction point. The
small-angle GDH experiment then began (E97-110: Chen, Deur, Garibaldi)
data-taking in late April. It was quickly discovered that the septum
magnet was mis-wired, and was not functioning as a dipole. Despite
this, the experiment was able to take useful data under these conditions
during the first stage (April-May) of the run. The septum was then
re-wired in June, and the second stage of the experiment successfully
took data in July and August. Since then, the hall has been down
for the installation of the second septum and the removal of the 
polarized $^3$He target, and for the recovery from the hurricane. \\

The schedule for the near future for Hall A includes commissioning of
the second septum magnet in December, followed by E94-107, High
Resolution Hypernuclear Spectroscopy in the 1-p shell
(Frullani, Garibaldi, LeRose, Markowitz, Hashimoto) which will
start early in January 2004. The delivery of beam with the very small
energy spread required for this experiment in parallel with the high
space-charge beam for the G0 experiment, which is scheduled to run
simultaneously in Hall C, will be a significant challenge for
accelerator operations. Following the Hypernuclear experiment will be
a return to HAPPEx parity violation experiments; a short initial run
on the HAPPEx-He (E00-114: Armstrong, Michaels) in mid-April followed
immediately by the majority of running for HAPPEx-II (E99-115: Kumar,
Lhuillier) on hydrogen, which will continue until late June. After
these experiments comes the installation of the Deeply Virtual Compton
Scattering (DVCS) experiments (E00-110: Bertin, Hyde-Wright, Ransome, 
Sabatie) and E03-106: Sabatie, Bertin, Hyde-Wright, Voutier) which should
commence data-taking in mid-August, and will continue through the end
of FY04. Following this, the first installation of the BigBite
spectrometer will commence. \\
