The Technical Design for the COMET Phase-I experiment is presented in this paper. COMET is an experiment at J-PARC, Japan, which will search for neutrinoless conversion of muons into electrons in the field of an aluminium nucleus (μ-e conversion, μ^- N → e^- N); a lepton flavor violating process. The experimental sensitivity goal for this process in the Phase-I experiment is 3.1×10^-15, or 90 7× 10^-15, which is a factor of 100 improvement over the existing limit. The expected number of

... nd events is 0.032. To achieve the target sensitivity and background level, the 3.2 kW 8 GeV proton beam from J-PARC will be used. Two types of detectors, CyDet and StrECAL, will be used for detecting the conversion events, and for measuring the beam-related background events in view of the Phase-II experiment, respectively. Results from simulation on signal and background estimations are also described.
