We re­port on re­cent up­grades of the ORNL Mul­ti­charged Ion Re­search Fa­cil­i­ty, and our ac­tiv­i­ties in the area of ECR ion source di­ag­nos­tic mea­sure­ments. The up­grades in­clude in­stal­la­tion of a new all per­ma­nent mag­net ECR ion source [1] on a high volt­age plat­form that in­creas­es our high en­er­gy beam pro­duc­tion ca­pa­bil­i­ty to 250keV/q, and in­stal­la­tion of a float­ing beam­line fed by a 10 GHz CAPRICE ECR ion source for pro­duc­ing de­cel­er­at­ed ion beams to en­er­gies as low as a few eV/q range. The pri­ma­ry ap­pli­ca­tion of all the pro­duced ion beams is to study fun­da­men­tal col­li­sion­al in­ter­ac­tions [2] of mul­ti­charged ions with elec­trons, atoms, and sur­faces. We also sum­ma­rize re­cent di­ag­nos­tic mea­sure­ments of the ECR plas­ma po­ten­tial and other plas­ma pa­ram­e­ters using an in-situ Lang­muir probe in­stalled in the ECR edge plas­ma and com­ple­men­tary mea­sure­ments [3] using an ex­ter­nal beam de­cel­er­a­tion method.
