TRANSCRIPT
HRIBF Users Workshop summary - ISOL Technology Session
presentations:
HRIBF ion sources (D. Stracener, HRIBF)Laser ion sources (Y. Liu, HRIBF)
Pure post acclerated beams:chemical techniques (C. Jost, ORAU & Mainz U) , photo-detachment (C. Havener, HIRBF)
gas stopping and re-accleration, He-jet (J.J. Das, UNIRIB) m-TOF (V. Shchepunov, Shimadzu Europe)
High power target development (D. Stracener, HRIBF)high density UC targets, 2- step targets (E. Spejewski)
! show of existing target & ion source capabilities! direction of development: cleaner beams & high power targets! need for improved quality & uptime driver beam

HRIBF Users Workshop summary - ISOL Technology Session
need: low energy exp.area for + ion beams
need: contineud first rate experiments
Key component: high reliability / uptime / intenisty driver

Conclusion: key for maintining a competitive HRIBF program is a proton-or heavy ion- driver that can provide for
(i) reliable ISOL beams from high power targets at 2000h+/y and(ii) has headroom for additional high intensity target development
