A new scheme to effectively and quickly cool highly charged ions (HCIs) is presented. The key item is the combination of high density electron plasma and cold positron plasma, which enables to realize a quick cooling (∼1 s) and at the same time the

The three-dimensional structure of the pancreatic ductular system (from the intercalated duct to the intercellular secretory canaliculus) is controversial and unclear. The aim of this study is to reveal the three-dimensional structure of the pancreat

A system to generate ultra-slow beams of highly ionized ions (HCls) is under construction at RIKEN for studying collision processes of slow HCls with atoms, molecules and surfaces. HCls beams produced with an ECR ion source are transported to a multi
