论文摘要
我们提出了直接从锻造和退火的坯料切片的中等谷物（MG）niobium（NB）圆盘的成本效益生产。该生产方法提供了清洁的表面条件和可靠的机械特性，亚毫米平均晶粒尺寸可导致稳定的SRF腔产生。我们建议将此材料应用于科学和工业前沿中的粒子加速器应用。科学应用需要高场梯度（> 〜40 mV/m），尤其是在脉冲模式下。工业应用需要在CW模式操作中具有中等梯度（〜30 mV/m）的高Q0值。该报告描述了最近证明的MG NB光盘生产，并讨论了在科学和工业前沿中高级粒子加速器中应用的未来前景。
We propose cost-effective production of medium grain (MG) niobium (Nb) discs directly sliced from forged and annealed billet. This production method provides clean surface conditions and reliable mechanical characteristics with sub-millimeter average grain size resulting in stable SRF cavity production. We propose to apply this material to particle accelerator applications in the science and industrial frontiers. The science applications require high field gradients (>~40 MV/m) particularly in pulse mode. The industrial applications require high Q0 values with moderate gradients (~30 MV/m) in CW mode operation. This report describes the MG Nb disc production recently demonstrated and discusses future prospects for application in advanced particle accelerators in the science and industrial frontiers.
