Optimum Operating Temperature for Accelerator Diskloaded Waveguide: Test Results from Sector 2

摘要

To keep the accelerator structures in proper tuned condition with variable applied RF power, the Cu-temperature of the structures should be kept constant. From the specifications in CN 102, we derive that a delta /PHI/ = +-10 exp 0 per ten-foot structure would be permissible to stay within a delta E/E of 0.5%. Further measurements should be performed to prove that all structures stay within this limit under the SLC operating conditions where the average RF power level will be in the order of ten times the average power used for the present test.
