“…The kick amplitude of trailing bunches can be measured at: 1) various distance from the preceding bunch; 2) various the preceding bunch oscillation amplitude; 3) various the preceding bunch current; 4) various the driving frequency etc. Similar measurement has been reported in single pass machine [ 16 ], it will be an interesting topic if the measurement is successful in the storage ring.…”

“…The choke-mode structure [19] and the damped detuned structure [20] are also studied as alternative designs. All three structure designs use the conventional manufacturing approach and were designed and tested in recent years [21][22][23][24][25][26][27][28]. A design of the X-band strong damped open structure is studied in this work as the third alternative design of the CLIC main linac.…”

Milling on two longitudinally split halves is one method to manufacture accelerating structures. This method is simple and allows one to avoid electromagnetic fields at bonding joints, making it attractive in manufacturing high-gradient accelerating structures. An X-band structure design with strong wakefield damping based on this manufacturing approach is studied in this work as an alternative design for the Compact Linear Collider (CLIC) main linac accelerating structures. The geometry of the structure is optimized to greatly reduce the surface fields, improve the efficiency, and suppress the wakefield. This structure features the baseline design of the CLIC main linac with additional advantages. This study may serve as a reference for designing other high frequency-band corrugated structures.

“…Due to the importance of the long-range transverse wakefield suppression in the CLIC main linac, an experimental verification in this aspect of the CLIC-G design had been carried out in the FACET facility [6]. Figure 2 shows the measured results together with GDFIDL [7] simulations on the same structure [8]. The transverse wakefield measured at the position of the second bunch was 5 V=pC=m=mm, which verified the long-range wakefield suppression of the CLIC-G design.…”

The Compact Linear Collider (CLIC) main linac uses waveguide damped structure as its baseline design. The current baseline structure design written in the CLIC Conceptual Design Report is named "CLIC-G." Recent activities on the CLIC-G design including high power tests on structure prototypes and the study of machining cost assessment had raised the need of reoptimizing the structure design to minimize the machining cost and the pulse surface temperature rise. This work presents optimization of the structure geometry, high-order-mode (HOM) damping loads and the design of a HOM-free power splitter for the input coupler. Compared to the current baseline design CLIC-G, the new structure design reduced the pulse surface temperature rise, input power and manufacturing cost and achieves better suppression to the long range transverse wakefield. Cell disks and damping loads for the new structure design are also more compact than those of the CLIC-G design.
