| The array of wide angle Cherenkov telescopes (WACT) has been constructed and operated at the Milagro observatory over the past few years. WACT consists of 6 atmospheric Cherenkov telescopes that measure the composition of cosmic rays in the energy region from several tens of TeV up to 500 TeV. Measurements in this energy region are critical in understanding composition measurements at higher energies. In this low energy region the composition is known through direct measurements. The results of my analysis show a composition that is consistent with other work near 200 TeV. At lower energies our results are inconsistent with direct observations. |
