[Industry -academia -government collaboration]
Iwate accelerator-related industrial study group

貴県ロゴマークThe International Linear Collider (ILC) is being considered for construction in Tohoku, with the Kitakami mountains located in southern
Iwate/northern Miyagi prefectures as the leading candidate site. Furthermore, Tohoku University is currently constructing a new synchrotron
radiation facility, NanoTerasu, which has led to a growing interest in accelerator-related business among local companies. To support this, the"Iwate Accelerator-Related Industry Study Group" was established in Iwate Prefecture. The group aims to (1) provide opportunities for local
companies to collaborate with industry, academia, and government in accelerator-related business, and (2) promote the enhancement oftechnical capabilities and expansion of business opportunities for local companies. We would like to highlight some of the activities
undertaken by this group.
