CIENCE L ABORATORY New Equipment for new Initiatives ARUNA Meeting-
June 12, 2014 Superconducting Solenoid for Nuclear Astrophysics:
SSNAP New injection magnet for the FN ion source upgrade To
maximize the use of TWINSOL for the study of transfer reactions for
quiescent and explosive stellar burning scenarios via the use of
inflight radioactive beams and a new helical spectrometer
(Bardayan). The upgrade of the injection system will achieve higher
mass resolution for AMS of high Z isotopes; that is important for
60 Fe life time analysis, p-process studies, and several other
applications (Collon).
