An Advanced NCRF Linac Concept for a High Energy e$^+$e$^-$ Linear Collider
We have explored a concept for an advanced Normal-Conducting Radio-Frequency (NCRF) C-band linear accelerator (linac) structure to achieve a high gradient, high power e$^+$e$^-$ linear collider in the TeV class. This design study represents the first comprehensive investigation for an emerging class...

| description | We have explored a concept for an advanced Normal-Conducting Radio-Frequency
(NCRF) C-band linear accelerator (linac) structure to achieve a high gradient,
high power e$^+$e$^-$ linear collider in the TeV class. This design study
represents the first comprehensive investigation for an emerging class of
distributed coupling accelerator topology exploring nominal cavity geometries,
frequency and temperature of operation. The structure features internal
manifolds for distributing RF power separately to each cell, permitting the
full structure geometry to be designed for high shunt impedance and low
breakdown. Optimized within operational constraints, we find that it is
advantageous for the structure to be cooled directly by liquid nitrogen (LN),
further increasing the shunt impedance. A crucial part of this design process
has been cost optimization, which is largely driven by the cost of peak RF
power. The first operation of a distributed coupling structure at cryogenic
temperatures and the nominal operating gradient 120 MeV/m is also presented,
demonstrating the feasibility of achieving high-gradient performance with a
cryogenically-cooled normal-conducting accelerating structure. |
