Initiatives - HRIBF Electron Driver

One method to enhance the intensity of very neutron-rich RIBs
is to use photofission instead of proton-induced fission. The
lower excitation produced by Bremsstrahlung (from electrons)
results in fission products with less neutron emission.
Calculations suggest that isotopes such as 132Sn could
be enhanced by 2 orders of magnitude over our present-day yields
from ORIC's proton-induced fission.

Possible electron driversFig. 1 - Rhodotron from IBASeveral different types of "turn-key" electron machines are available today. A rhodotron from IBA is appealing due to its small size which could possibly fit within the existing facility although some construction might be necessary as one scheme requires the machine to be elevated above the target. LINACs have been around for years and have proven reliable, efficient machines capable of running many years. One possible LINAC solution is shown below; this Accel LINAC is located at the Paul Scherrer Institut in Switzerland.
Fig. 2 - Electron LINAC from Accel The size of this project is well over 5 M dollars and is restricted to improving only those neutron-rich beams produced by fission. This project could begin as early as FY09 and would be a turn-key operation. If this project is funded, we would balance this project and the ORIC axial injection project in order to minimize down time. Interactive chartsThese charts are in svg format and use java script.
