| | The International Linear Collider (ILC) will require two
dipole cavities to "crab" the electron and positron bunches
prior to their collision. It is proposed to use two 9 cell
SCRF dipole cavities operating at a frequency of 3.9 GHz,
with a transverse gradient of 3.8MV/m in order to provide
the required transverse kick. Extensive numerical
modelling of this cavity and its couplers has been
performed. Aluminium prototypes have been
manufactured and tested to measure the RF properties of
the cavity and couplers. In addition single cell niobium
prototypes have been manufactured and tested in a
vertical cryostat. | |

| | We investigate the electromagnetic field excited by a
train of multiple bunches in the main superconducting
linacs of the International Linear Collider (ILC). These
e.m. fields are represented as a wake-field. Detailed
simulations are made for modes constituting the longrange
wake-field in new high gradient cavities. In
particular, we focus our study on the transverse deflecting
modes in high gradient cavity designs known as "Ichiro",
in which the central cells have iris radius of 30 mm.
These cavities have a reduced iris compare to the TESLA
design and will have more intense wake-fields. Several
software packages solving the electromagnetic field,
employing different algorithms have been used to model
the cavity. The performance of these codes is compared. | |
