Neutron instruments at J-PARC; Toward the state-of-the-art facility

Kamiyama, Takashi; Suzuya, Kentaro

Since the construction of the MLF building was completed in April 2007, over ten instruments have been installed in the MLF experimental halls. At 14:25 on May 30th, 2008, the first neutron was detected at one of five Day-One instruments. In July 2008, we called for the first J-PARC general user proposals for the second half of Japanese FY2008. For each of the six instruments, a total of 23 days of experiments were successfully carried out as the first MLF user program. Most recently, the general user proposals for ten instruments were called for the second half of Japanese FY2010 for 60 days. Now (Fall 2010), in addition to the above ten instruments, two more instruments are used by project teams, and we are constructing additional six instruments. Instruments strategy and first data are also reported in this article.
