Stable Beams Available from ATLAS

Updated August, 2009

	Beam currents listed in the table were obtained with naturally occurring material for the given isotope.
	The maximum energy quoted corresponds to the that computed with the optimal charge state. Higher energies are possible by using another charge state or by double stripping.

a	Other isotopes available with currents proportional to their abundance. For more beam current isotopically enriched material may be used, but the User should, in general, contact the User Liaison or ATLAS Operations to check on the availability of enriched material.
b	Indicates elements for which isotopically enriched material has been successfully used in the past.
c	Allowed maximum radiation may limit beam current.
*	The maximum energies in Area II are about 0.6 times these values.
