Measured Yields from HRIBF RIB Production Targets (2001)

• Note added July 14, 2005: Check this table for more recent values.
• Note added Nov 9, 2004: Check recent newsletters for actual yields on target. Some beams such as Sn, are stronger than by factors as high as 10 or more.
• Note added Feb. 16, 2001: This uranium carbide target has been proven to withstand 10 uA of proton beam from ORIC.
• Beam on target prediction includes charge state fraction and a factor to account for transmission losses and inaccuracies in the magnitude of the charge state fraction.
• Actual charge state selection for an individual experiment depends on many factors. The estimates calculated here are for planning purposes.
• The range of acceptable tandem voltages is 1-25 MV. Running above 23 MV requires significant conditioning of the tandem and may not always be available. Operation above 24 MV may be possible but at a significant cost in time and stability of the beam is usually not optimum.
