The DeeMe experiment is planned at J-PARC Materials and Life Science Experimental Facility. The experiment aims to search for the muon to electron conversion in the nuclear field, which is one of the charged lepton flavor violation processes, with a single-event sensitivity of $10^{-14}$. While the processes are forbidden in the Standard Model of particle interactions, some theories beyond the Standard Model predict the existence of such processes at observable rates. Therefore, the experimental signature would be clear evidence of new physics. Preparation for the experiment is now ongoing. Four tracking detectors have been manufactured in 2017. Using these detectors and a spectrometer magnet, we took data of the momentum spectra of muon Decay in Orbit for a medium momentum region by using three kinds of targets made of C, Si and SiC. The current status of the preparation for the DeeMe experiment is reported in this paper.
