Procurement complete for one of four types of FRIB cavities
Superconducting radio frequency (RF) cavities accelerate ions from low velocity to about half the speed of light. FRIB will use four different types of superconducting cavities, each optimized for a specific velocity range (β=v/c=0.041, 0.085, 0.285 and 0.53 cavities). In total, FRIB requires just over 330 individual cavities. Manufacturing of all 19 of the 0.041 cavities has been completed at the vendor and all are now in hand at FRIB, marking the significant completion of one of four types of cavity procurements.
