摘要:

本文介绍了一台高能(0.5 - 5 TeV)、高光度(1034 - 1035 cm ~(-2)sec ~(-1))e ~+e直线对撞机的CLIC研究。束加速使用高频(30 GHz)正常的导电结构在高加速场(150 MV/m)显着减少的长度,因此,成本的直线加速器。使用线性对撞机的一般标度律导出的参数,束的稳定性示出为类似于较低的频率设计,尽管强的尾场依赖于频率。介绍了一种新的用于射频功率产生的高性价比的驱动束产生方案,即所谓的“双束加速”方法。它使用一个电子枪和一个满载正常导电直线加速器在低频率(937 MHz)运行,以产生和加速驱动束聚束,并通过在压缩机环中的漏斗形成射频倍增,以产生所需的聚束结构。最近30 GHz的硬件发展和CLIC测试设备(CTF)的结果进行了说明。

英文摘要:

The CLIC study of a high-energy (0.5 - 5 TeV), high-luminosity (1034 - 1035 cm-2 sec-1) e+e- linear collider is presented. Beam acceleration using high frequency (30 GHz) normal-conducting structures operating at high accelerating fields (150 MV/m) significantly reduces the length and, in consequence, the cost of the linac. Using parameters derived from general scaling laws for linear colliders, the beam stability is shown to be similar to lower frequency designs in spite of the strong wake-field dependency on frequency. A new cost-effective and efficient drive beam generation scheme for RF power production by the so-called "Two-Beam Acceleration" method is described. It uses a thermionic gun and a fully-loaded normal-conducting linac operating at low frequency (937 MHz) to generate and accelerate the drive beam bunches, and RF multiplication by funnelling in compressor rings to produce the desired bunch structure. Recent 30 GHz hardware developments and CLIC Test Facility (CTF) results are described.
