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.

Description
:
It
is a sticker with very small holes on the surface . Light filters through and
allows you to see out of the window with an almost solid image showing through
on the other side. It is common to use on the rear window of vehicles or bus
windows. It can also be applied on shop front windows to make decoration or
advertise your products and service . Most these one way vision stickers
appears on the window of metro (subway ). We have two kinds of one way vision
sticker ,one is adhesvie on the back of the material and one is adhesive on the
printed image side ( this means you can apply the stickers on the inside of the
window ,then see the image through the window from outside ,this way can
protect the image very well ,it wont be easy moved away and scratched .
Specification :
Largest seamless size :
150cm ( 4.9feet ) ,length can be reach 30 meters .
Waterproof and uv
protect
Application : window or
glass
MOQ: 1 PCS
How to appply to the
window for large size : clean up the window first ,then move away the back paper
on the adhesive side and attached the one way vision sticker on the window step
by step .
Single side printing on
the one way vision sticker
