Popis: Previously, fixed angle Laser-Compton Scattering (LCS) experiments have been conducted at the terminal of the 100 MeV LINAC of the Shanghai Institute of Applied Physics, using SINAP-I and SINAP-II facility. Sub-MeV energy continuously tunable laser-Compton light source device (SINAP-III) is an updated facility that will allow the collision angle between the laser and electron beam continuously adjustable from 20 $^\circ $ to 160 $^\circ $ . This new feature will enable convenient control on the maximum energy of the generated ${\rm X}/\gamma$ ray in a wide energy region, especially when the energy of electrons cannot be momentarily adjusted, e.g. on the storage ring. Keeping the electron beam and laser beam waist coincident at arbitrary angle is crucial for LCS gamma-ray production, an interaction chamber containing a rotatable bracket that holds a series of plane mirrors and convex lens is presented. This work is a summary of its design. The simulation of photon production’s variation caused by the systematic errors is performed using a MC code. The accuracies of installation and adjustment of mirrors and lens are given according to the simulation results. The sizes of these optical devices are also optimized.
