A large amount of outgassing from the laminated cores in the pulse-operating magnets is one of the causes of pressure rise in an accelerator vacuum chamber. Outgassing rate measurements were carried out for a thousand of 0.1 mm thickness steel laminations, being stacked, in the compressed and uncompressed conditions. The measured rates of these samples did not show a significant difference, and indicated a t-1/2 time dependence. A pre-baking treatment for the laminated core samples was also examined.
