Abstract
The MEGA experiment, which searched for the muon- and electron-number violating decay ${\ensuremath{\mu}}^{+}\ensuremath{\rightarrow}{e}^{+}\ensuremath{\gamma},$ is described. The spectrometer system, the calibrations, the data taking procedures, the data analysis, and the sensitivity of the experiment are discussed. The most stringent upper limit on the branching ratio, $\mathcal{B}({\ensuremath{\mu}}^{+}\ensuremath{\rightarrow}{e}^{+}\ensuremath{\gamma})<1.2\ifmmode\times\else\texttimes\fi{}{10}^{\ensuremath{-}11}$ with $90%$ confidence, is derived from a likelihood analysis.
