This thesis presents the measurement of the inclusive cross section for central photons with transverse momentum greater than 30 GeV/c and calorimeter isolation < 2 GeV using 2.5/fb of data collected by the CDF detector at the Fermilab Tevatron Collider. This measurement includes a factor of 6 more data than the last published result, extending its transverse momentum coverage by 100 GeV/c. The cross section is measured up to 400 GeV/c, and tests the theoretical predictions over 6 orders of magnitude, one order of magnitude more than in previous results.
