Design of a Copper Cavity for Hls
نویسندگان
چکیده
A 204MHz all copper RF cavity was designed for the phase II project of Hefei Light Source (HLS). The requirements of the storage ring, which will operate in General Purpose Light Source (GPLS) mode and High Brightness Light Source (HBLS) mode, determine the main parameters of the cavity. On the basis of the simulation of SUPERFISH, three kinds of cavity shape were designed, and one optimum shape was selected at last. The HOMs of the cavity were calculated with URMEL-T and they would be suppressed by the HOMs couplers. In addition, the construction techniques of the cavity, such as how to weld the cavity components and fabricate the cooling water channels, are described in this paper.

An efficient CAD tool for High-Level Synthesis of VLSI digital transformers
Digital transformers are considered as one of the digital circuits being widely used in signal and data processing systems, audio and video processing, medical signal processing as well as telecommunication systems. Transforms such as Discrete Cosine Transform (DCT), Discrete Wavelet Transform (DWT) and Fast Fourier Transform (FFT) are among the ones being commonly used in this area. As an illu...
متن کاملUsing Vivado-HLS for Structural Design: a NoC Case Study
There have been ample successful examples of applying Xilinx Vivado’s “function-to-module” high-level synthesis (HLS) where the subject is algorithmic in nature. In this work, we carried out a design study to assess the effectiveness of applying Vivado-HLS in structural design. We employed Vivado-HLS to synthesize C functions corresponding to standalone network-on-chip (NoC) routers as well as ...

متن کاملGuest Editors' Introduction: Raising the Abstraction Level of Hardware Design
DESIGN COMPLEXITY is continually rising with the higher levels of integration implied by Moore’s law. Functional complexity increases with our ability to incorporate more computation in SoCs and to create more complex applications. Additional complexity is also introduced in the design process by the need to control power consumption and to tackle challenges with respect to physical timing clos...
متن کاملStudy of prophenoloxidase activating system of freshwater crayfish (Pontastacus leptodactylus)
Phenoloxidase (Po) activity was measusred spectrophotometrically in serum, plasma and haemocytes (HLS) of the freshwater crayfish (Pontastacus leptodactylus). The highest activity was found in HLS suggesting that the haemocytes are the major source of the Po or its proform prophenoloxidase (proPO) in crayfish. Furthermore, the enzyme activity in serum samples was reduced after freezing the samp...
