Outline of Final Research Achievements

We have successfully selected the candidate material for the target gas chamber and optimized the experimental setup using newly developed simulation code. Based on the result, all experimental apparatus have been constructed and installed to the beam line. We unfortunately could not perform data taking due to J-PARC regulation. The experiment will be carried out within the next fiscal year.
