“…26 Al content was initially measured on higher voltage accelerators with AlO À ions which have an EA of 2.6 eV, involving the Cs(6s) ground state in RET. Flarend et al found greater ion output for AlN À [34]. This arises from the 1.90 eV EA of AlN À that allows RET with the copious Cs(5d) in a recess.…”

“…The AMS technique can be applied to analyzing different radioisotopes besides 14 C [38][39][40][41][42], and to the analysis of positive ions for some isotopes. A list of three isotopes and differing cyclotron parameters associated are given in table 2.…”

A small cyclotron has been designed for accelerator mass spectrometry, and the injection beam line is constructed as part of prototyping. Mass resolution of the cyclotron is estimated to be around 4000. The design of the cyclotron was performed with orbit-tracking computations using 3D magnetic and electric fields, and beam optics of the injection line was calculated using the codes such as IGUN and TRANSPORT. The radial injection scheme is chosen to place a beam on equilibrium orbit of the cyclotron. The injection line includes an ion source, Einzel lens, rf buncher, 90 ˚dipole magnet, and quadrupole triplet magnet. A carbon beam was extracted from the front part of the injection line. An rf cavity system for the cyclotron was built and tested. A multi channel plates (MCP) detector to measure low-current ion beams was also tested. Design considerations are given to analyzing a few different radioisotopes in form of positive ions as well as negative ions.

“…The measurement of 26 Al usually involves preparation of Al 2 O 3 targets because of their ease of preparation and stability. In an investigation into the use of several compounds as targets, Flarend et al 109 found that AlN had potential for increasing the sensitivity and precision of analysis at low Al concentrations. The ion beam produced from AlN was at least five times higher than that produced from Al 2 O 3 but, rather curiously, depended on exposure of the AlN target to air prior to analysis.…”
