Development of Ceramic Vacuum Chambers and Research on Their Impedances SHANG Lei, ZHAI Yuan-ji, WANG Xiang-e, LENG Yong-bin, WANG Lin, FAN Kuan-jun (National Synchrotron Radiation of the University of Science and Technology of China, The result of the calculation is: coating IZ/nl=0. 8R If the square resistance of the coated 4-segment ceramic vacuum chamber with sheet resistance 1 is approximately 1.5 U, the proportion is larger. The Heife-Bane broadband impedance model has certain advantages compared with the broadband resonance model. Many fitting results show that the fitting of the measured data is obviously worse than the numerical calculation results. The reason is that the errors of the measured wake field and loss factor are relatively large, and their relative deviations from the theoretical values ​​are 10% and 30%, respectively. However, the results still basically indicate the broadband impedance of the coating vacuum chamber. The fitting process shows that the impedance of the impedance wall occupies a considerable proportion, so the coating can be further thickened. 4 Conclusion From the measured K values ​​and the fitted longitudinal broadband impedance parameters, the current coating thickness can still be further increased. If the sheet resistance of the film is reduced from the current about 1 to 3UK value and the longitudinal broadband impedance will be further reduced. And from the magnetic Wang Guangwei.

a kind of Welded Mesh Fence, has simple production process. The wire mesh is welded by high quallity wave shaped galvanized wire, then PVC coated.Then, wire mesh is connected to the profiled post with specical clips. Due to the advantages of simple structure, easy installation and lower cost, euro fence is widely used in industrial, agricultural, municipal, and transportation projects,Main market is Europe, and most countries of the world also have some demand .
