“…In order to achieve the desired coupling constant and the nominal frequency in operating mode, the geometry includes two half accelerating cavities and one coupling cavity between them (figure 2) were considered and the cavities dimensions as well as overlap between the side coupling cavity and accelerating cavities were optimized as follows [19,23]:…”

The design and construction of a 6 MeV electron linear accelerator (e-Linac) was defined in the Institute of Nuclear Science and Technology (NSTRI) for cargo inspection and medical applications. For this accelerator, a side coupled standing wave tube resonant at a frequency of 2998.5 MHZ in π/2 mode was selected. In this article, the authors provide a step-by-step explanation of the process of the design for this tube.The design and simulation of the accelerating and coupling cavities were carried out in five steps; (1) separate design of the accelerating and coupling cavities, (2) design of the coupling aperture between the cavities, (3) design of the entire structure for resonance at the nominal frequency, (4) design of the buncher, and (5) design of the power coupling port. At all design stages, in addition to finding the dimensions of the cavity, the impact of construction tolerances and simulation errors on the electromagnetic parameters were investigated. The values obtained for the coupling coefficient, coupling constant, quality factor and capture efficiency are 2.11, 0.011, 16203 and 36%, respectively.The results of beam dynamics study of the simulated tube in ASTRA have yielded a value of 5.14 π-mm-mrad for the horizontal emittance, 5.06 π-mm-mrad for the vertical emittance, 1.17 mm for the horizontal beam size, 1.16 mm for the vertical beam size and 1090 keV for the energy spread of the output beam.

“…Detailed design of the resonant coupled cavity structures, carried out with major assistance from LANL, is now complete, and a close partnership with the Institute for High Energy Physics, Beijing, is being forged for the construction of this primary system [23,24]. The CCL modules will be the longest chains of side-coupled resonators ever operated.…”

The SSC linear accelerator will generate a 25 mA, 600 MeV, H-beam with transverse normalized rms emittance less than 0.3 IC mmomrad in 9.6 ps pulses at a 10 Hz repetition rate. The Linac will ultimately have to operate with an availability for Collider filling in excess of 98%. In addition, the Linac will provide beams to service the Test Beams facility and may be delivering beam to a Proton Radiotherapy Facility. This paper presents an overview of the status of design, procurement, fabrication, civil construction, foreign contributions and commissioning plans, and directs the reader to additional details available in other presentations to this Conference.
