  Texas A&M is cur­rent­ly con­fig­ur­ing a scheme for the pro­duc­tion of ra­dioac­tive-ion beams that in­cor­po­rates a light-ion guide (LIG) cou­pled with an ECRIS con­struct­ed for charge-boost­ing (CB-ECRIS). This scheme is part of an up­grade to the Cy­clotron In­sti­tute and is in­tend­ed to pro­duce ra­dioac­tive beams suit­able for in­jec­tion into the K500 su­per­con­duct­ing cy­clotron. The prin­ci­ple of op­er­a­tion is the fol­low­ing: a pri­ma­ry beam from the K150 cy­clotron in­ter­acts with a pro­duc­tion tar­get placed in the gas cell. A con­tin­u­ous flow of he­li­um gas main­tains a con­stant pres­sure of 500 mbar max­i­mum in the cell. Re­coils are ther­mal­ized in the he­li­um buffer gas and eject­ed from the cell with­in the gas flow through a small exit hole. The pos­i­tive­ly charged re­coil ions (1+) are guid­ed into a 2.5 m long, rf-on­ly hexapole and will be trans­port­ed in this man­ner on-ax­is into the CB-ECRIS. The CB-ECRIS op­er­ates at 14.5 GHz and has been spe­cial­ly con­struct­ed by Sci­en­tif­ic So­lu­tions of San Diego, Cal­i­for­nia for charge-boost­ing. An overview of the en­tire pro­ject will be pre­sent­ed with de­tails on dif­fer­ent con­struc­tion phas­es. Spe­cif­ic mea­sure­ments and re­sults will be pre­sent­ed as well as fu­ture de­vel­op­ment plans.
