For high­er fre­quen­cies 4-VANE struc­tures are more com­mon. The ad­van­tages of 4-Rod struc­tures, the greater flex­i­bil­i­ty for tun­ing and being more com­fort­able for main­te­nance, are mo­ti­vat­ing the de­vel­op­ment of a 4-Rod RFQ for high­er fre­quen­cies than 216 MHz. In par­tic­u­lar a 325 MHz RFQ with an out­put en­er­gy of 3 MeV is need­ed for the pro­ton linac for the FAIR pro­ject of GSI. This paper re­ports about the de­sign stud­ies and the lat­est de­vel­op­ments of this RFQ.
