| Abstract | An ISOL (Isotope Separator On Line) type of RIB (Rare Ion Beam) facility is being developed at our centre. The post-acceleration scheme will consist of a Radio Frequency Quadrupole (RFQ) followed by a few IH LINAC cavities further augumentation of energy using SC QWRs will be taken up at a later stage. The first two IH cavities have been designed for 37.6 MHz frequency like the preceding RFQ to keep the RF defocusing smaller. Explosively bonded copper on steel has been used for the fabrication of the IH cavities and the inner components have been from of ETP grade (UNS C11000) copper. Also, we have adopted an octagonal cross-section for the cavity structure to avoid fabrication complicacies. The first and second cavity have inside lengths of 0.62 and 0.97 m respectively and the inside separation between two opposite sides of the octagon is 1.72 m. Thermal analysis of the cavities has been carried out and cooling configurations have been optimized accordingly to control the temperature rise of the LINACs. Detailed mechanical analysis has been carried out to reduce the deflection of the LINAC components under various loads. Design and fabrication aspects of these two cavities and results of the low power tests will be reported in this paper. |
