A new cry­omod­ule with seven low-be­ta su­per­con­duct­ing radio fre­quen­cy (SRF) quar­ter wave nio­bi­um cav­i­ties has been de­signed and con­struct­ed as an en­er­gy up­grade pro­ject for the ATLAS ac­cel­er­a­tor at Ar­gonne Na­tion­al Lab­o­ra­to­ry. The tech­nol­o­gy de­vel­oped for this pro­ject is the basis for the next gen­er­a­tion su­per­con­duct­ing heavy ion ac­cel­er­a­tors. This paper will dis­cuss the meth­ods em­ployed to tune the cav­i­ties eigen­fre­quen­cy to match the ac­cel­er­a­tor mas­ter os­cil­la­tor fre­quen­cy and the de­vel­op­ment of the RF sys­tems used to both drive the cav­i­ty and keep the cav­i­ty phase locked dur­ing op­er­a­tion.
