A standard bunching system is usually composed of a SW PB, a TW B and a standard accelerating structure. In the industrial area, the bunching system is usually simpli-fied by eliminating the PB and integrating the B and the standard accelerating structure together to form a β-varied accelerating structure. The bunching efficiency for this kind of simplified system is lower than that for the stand-ard one. The HB has been proved to be an innovative attempt to reduce the cost but preserve the beam quality as much as possible. Here, the HAS is proposed by inte-grating the PB, the B and the standard accelerating struc-ture together to exclusively simplify the standard bunch-ing system. Compared to the standard bunching system, the one with the HAS is more compact, and the cost is lowered to the largest extent without fairly degrading the beam performance. The proposed HAS can be widely applied in the industrial area.

In an electron linac, the composition of the bunching system is determined by the synthetical consideration of the beam performance and the construction cost. In the industrial area, the bunching system is usually simplified to reduce the construction cost by eliminating the PB and integrating the B and the standard accelerating structure to form the β-varied structure. The bunching performance for this kind of system is relatively worse than that for the standard one. To keep the beam performance of the standard bunching system and reduce the construction cost as much as possible, the HAS is proposed by integrating the PB, the B and the standard TW accelerating structure together. The HAS can be widely applied in the industrial area to enhance the beam performance of the industrial linac but not increase the cost. In this paper, the design studies on an S-band (2856 MHz) HAS is presented. The HAS studied here is composed of 2 SW cells, 40 TW cells and 2 coupler cells. The on-axis electric field amplitude distribution simulated by HFSS can fully meet the beam dynamics requirement.

The bunching efficiency for this kind of simplified system is lower than that for the stand-ard one.

In an electron linac, the composition of the bunching system is determined by the synthetical consideration of the beam performance and the construction cost. In the industrial area, the bunching system is usually simplified to reduce the construction cost by eliminating the PB and integrating the B and the standard accelerating structure to form the β-varied structure. The bunching performance for this kind of system is relatively worse than that for the standard one. To keep the beam performance of the standard bunching system and reduce the construction cost as much as possible, the HAS is proposed by integrating the PB, the B and the standard TW accelerating structure together. The HAS can be widely applied in the industrial area to enhance the beam performance of the industrial linac but not increase the cost. In this paper, the design studies on an S-band (2856 MHz) HAS is presented. The HAS studied here is composed of 2 SW cells, 40 TW cells and 2 coupler cells.
