Eigenmodes in two simplified chamber structures studied for spurious microwaves in the APS storage ring beam chamber.

PDF Version Also Available for Download.

Description

The vertical readback errors are one order of magnitude greater than the horizontal ones in the APS storage ring beam chamber. To learn and solve this problem, we simulate the eigenmodes in two chamber structures, which are simplified from the APS storage ring beam chamber, and find their dependence on the variation of the chamber structures. These two structures are introduced as the solutions to separate and then restrain the spurious microwave modes by using a metal short block and a plate inside the chamber. The short block can shift and separate the frequencies of every mode evidently.
