A new 250kV high-voltage platform has been installed at the ORNL multicharged ion research facility (MIRF) to extend the energy range of multicharged ions available for experimental investigations of their collisional interactions with electrons, atoms, molecules and solid surfaces. For the production of the multiply charged ions, a new all-permanent magnet electron cyclotron resonance (ECR) ion source, designed and fabricated at CEA/Grenoble, is being used. After a brief summary of the project background and the expanded research program made possible upon its completion, design details of the new platform, associated beam transport and control system are presented, together with information on the design and performance of the new ion source.
