Shanghai Light Source Storage Ring Stainless Steel Vacuum Chamber - Vacuum Technology Network

Shanghai Synchrotron Radiation Facility adopted stainless steel vacuum chambers. The main reason is that about half of the material of an aluminum alloy vacuum chamber must be machined by CNC, whereas there is almost no loss of material in processing a thin walled stainless steel vacuum chamber. Thus, a great amount of money is saved and the machining cycle is greatly shortened. However, it is extremely difficult for the size accuracy of complex thin walled stainless steel vacuum chambers to be equivalent to that of the machine - processed aluminum alloy vacuum chambers.
