TD26 CLEX Structure

TD26 CLEX Super Accelerating Structure design has been integrated and presented with the following features:

- Two Accelerating Structure modules (AS) are brazed together to form a

Super Accelerating Structure (SAS)- Compact couplers, new design waveguides and wakefield monitors with TE-

and TM-like mode pick up have been integrated to the structure- Cooling system has been integrated to vacuum manifolds and external

piping has been implemented with connectors and pipes- Damping material has been installed to vacuum manifolds- Alignment spheres have been included to design- Accelerating Structure have been designed so that it is able to assemble to

adjacent structures with flexible interconnections- Bonding, brazing including pre-assembly brazing, mechanical assembly and

welding steps have been validated
