Description
The International Linear Collider (ILC) is the future electron-
positron collider machine that will reach the energy frontier of
elementary-particle physics at the center-of-mass energy of 500 GeV.
The ILC is expected to reveal the precise properties of the Higgs
particle and the physics beyond the standard model. The ILC group
published the Technical Design Report (TDR) of the machine
in June 2013. In the TDR, it is described that the energy
consumption of ILC is about 200 MW and the beam energy of electron
and positron is 10 MW in total which is dumped after the interaction
of beams. In the situation that recent progress of plasma-wakefield
physics, we started to study on the recovery of eletron and positron
energies at the beam dump by the method of plasma-wakefield deceleration,
where the recovered energy will be re-used for the operation of the machine
and we can expect less radiation problem at the beam dump. In this
article, the recent status of this study will be presented.
