  We present data for relativistic hot electron production by the Texas
Petawatt Laser irradiating solid Au targets with thickness between 1 and 4 mm.
The experiment was performed at the short focus target chamber TC1 in July
2011, with laser energies around 50 J. We measured hot electron spectra out to
50 MeV which show a narrow peak around 10 - 20 MeV plus high energy exponential
tail. The hot electron spectral shape differs from those reported for other PW
lasers. We did not observe direct evidence of positron production above
background.
