Abstract: This paper presents a design study of adjustable mirror bender system. This system is functioned to adjust beam size focusing on sample in synchrotron light beamline (BL3) at synchrotron light research institute, Thailand. The design utilizes COSMOS program to help in finite element method for simulating the relation of radius value of mirror in function of various action force applying on curvature mirror. Al Alloy(6061) and Zerodur size 40mm x 300mm x 15mm are used as study mirror. All of structures of mirror bender system are built by stainless steel. The simulation of system is to apply a forces to adjust the mirror radius in 50,000 – 60,000 mm range for using it in real circumstance in beamline system. The results of study show the forces in 100-150 N range for Al Alloy (6061) and 150-200 N range for Zerodur giving proper curvature radius values. In contrast, the apply force is more than 300 N calculating from 80% of stress value of mirror, that damages the sy!
stem. Finally, a prototype of the system is designed and built by using Al Alloy(6061) as a bender mirror. The testing results of the prototype show that apply forces just in range of 50-100 N are suitable enough for the system. That means the apply force of the prototype is 50 N less than the simulation. Therefore, this mirror bender system is ready and suitable for installation in synchrotron light beamline.
