    "abstract": "Sympathetic laser cooling of ions stored within a linear-geometry, radio\nfrequency, electric-quadrupole trap has been investigated using computational\nand theoretical techniques. The simulation, which allows 5 sample ions to\ninteract with 35 laser-cooled atomic ions, revealed an instability heating\nmechanism, which can prevent ions below a certain critical mass from being\nsympathetically cooled. This critical mass can however be varied by changing\nthe trapping field parameters thus allowing ions with a very large range of\nmasses to be sympathetically cooled using a single ion species. A theoretical\nexplanation of this instability heating mechanism is presented which predicts\nthat the cooling-heating boundary in trapping parameter space is a line of\nconstant $q_u$ (ion trap stability coefficient), a result supported by the\ncomputational results. The threshold value of $q_u$ depends on the masses of\nthe interacting ions. A functional form of this dependence is given.",
