Major initiatives are well underway for ion accelerators for nuclear astrophysics, such as FRIB, RAON and others.  With the success of SNS, high intensity proton accelerator projects are progressing, such as ESS, PIP-II, Indian SNS, along with ADS ambitions, such as CADS and IADS.  The aim of WG2 is to address the major on-going issues for each type of accelerator, how these issues are being addressed, as well as the needed developments. Demonstrated and needed advances in couplers and tuners for both accelerator classes should be included.  Please avoid presentations that give project status summaries - more suited to other conferences. . 2.
