Abstract_FL [Background]The Shanghai Synchrotron Radiation Facility(SSRF)is a user facility that requires continuous addition of new beamlines to meet the needs of an increasing number of users.Adding new insertion devices(IDs)to the synchrotron radiation light source is a complex and critical task.[Purpose]This study aims to highlight the important considerations of dual IDs installation and commissioning when adding new beamlines to synchrotron light sources.[Methods]The newly added dual IDs 04IVU(undulator)and 04Wigger for new beamline added to SSRF were taken as an example,key tasks that need to be addressed in the accelerator aspect of engineering were presented in details.Firstly,the design parameters and magnetic measurement results of the IDs were introduced,and the SPECTRA program was employed to calculate the spectral brightness of dual IDs.Then,problems encountered during the installation process and their solutions were discussed,and an orbit feedforward compensation system equipped with corrector coils for mitigating orbit distortions caused by the IDs was implemented.Finally,the significance,methods,and results of vacuum cleaning work in the front-end area,together with a summary of the issues encountered during the trial operation and corresponding solutions were outlined.[Results]The maximum spectral brightness of 04IVU and 04Wiggler are 5.86×1019 Photon·s-1·mm-2·mrad-2·(0.1%B.W.)-1 and 2.75×1015 Photon·s-1·(0.1%B.W.)-1 at photon energy of 3 keV,respectively.After compensation,the distortions of 04IVU and 04Wiggler are reduced to below 2 μm.[Conclusion]The dual IDs have been successfully installed and commissioned.This study provides reference value for installation and commissioning of accelerators associated with the new beamline in other synchrotron radiation light sources.
