| | The large efforts have been concentrated on Nb
cavities for International Linear Collider (ILC). The
maximum accelerating field gradient of Nb cavities is
limited about 50 MV/m due to Hcsh. MgB2 (MgB2) have
higher Tc than Nb and expected to have higher Hcsh. Thin
films of MgB2 on Nb is useful to increase future ILC
energy upgrading.
At KEK, the preliminary test of thin films on Nb by
Pulse Laser Deposition(PLD) method have been started
and initially the direct deposition of MgB2 film on Nb
discs and single cell cavity was studied. | |
