We have designed the BPM PU based on capacitive buttons for use in the
KOMAC (Korea Multi-purpose Accelerator Complex), the high-intensity
proton linac that are under development at the KAERI (Korea Atomic
Research Institute), Korea. The KOMAC is aiming to produce CW 20 mA beam
current at the 100 MeV energy. We have chosen the button-type PU since it
is easier to fabricate than other type PUs including the stripline, and
it could provide enough signal power because of the high beam current.
The PU sensitivity was calculated by the MAGIC that is a kind of the
Particle-In-Cell code that originates from the plasma science community.
The utilization of the MAGIC code is especially useful for BPM PUs in the
low-beta sections of the accelerator, because it is difficult to obtain
the PU sensitivity experimentally due to the difficulties in simulating
the low-beta beams by the electromagnetic waves in a test bench. In this
presentation, we report on the design of the BPM PU based on the MAGIC
calculation.
