Abstract :
An RFQ model linac of 62 cm long at a frequency of 200 MHz was constructed using a computer program "QKEK" developed at KEK. QKEK generates an RFQ linac, calculates beam dynamics, and provides geometrical data of vanes for a numerically controlled milling machine. A detailed study of rf characteristics was performed. The accelerating and focusing fields measured by the bead perturbation method on axis agree well with the design values. An RFQ linac, which accelerates protons from 50 keV to 750 keV, is designed.
