A first look at reconstructed data from the GlueX detector

Construction of the GlueX detector in Hall D at the Thomas Jefferson National
Accelerator Facility has recently been completed as part of the 12 GeV Upgrade
to the facility.  The detector consists of a barrel region containing devices
for tracking charged particles and a lead-scintillator calorimeter for detecting
photons, and a forward region consisting of two layers of scintillator paddles
for time-of-flight measurements and a lead-glass electromagnetic calorimeter.
The electron beam from the accelerator is converted into a photon beam by
inserting a diamond radiator, thereby producing a coherent bremsstrahlung
spectrum of photons impinging on a 30 cm-long LH2 target.  The energy of the
photon beam is determined using a tagging spectrometer.  A commissioning
run took place in Spring of 2015 during which all of the detector components
were read out.  Preliminary calibrations have been determined to a level
sufficient to allow reconstruction of final states with several charged tracks
and neutral particles.  A first look at results of reconstruction of events
using the GlueX detector will be presented.
