Lab test configuration of CLIC G accelerating structure

Lab. test configuration of CLIC G accelerating structure Dmitry Gudkov BE/RF 1

Accelerating structure components 1. Accelerating structure mockup 2. Vacuum/damping manifold (2 types) 3. Cooling system 4. Interface waveguides 2

Accelerating structure components Accelerating structure mock-up 1. Made of CU-OFE cylinder with diameter 80 mm. 2. Internal surface area calculation was done with CATIA Engineering optimizer module: 3

Accelerating structure components 4

Accelerating structure components To seal cooling holes there is the special cover is being used: The cover will be soon optimized according to module-module interconnection design. 5

Accelerating structure components Manifold consists of two halves bonded together. Damping material is being inserted to one of halves before bonding operation: TYPE 1 6

Accelerating structure components Surface area and damping material are the same as for CLIC module TYPE 2 For connection to the main vacuum tank there is a special tube brazed to the manifold. After all of brazing operations a vacuum flange will be welded to this tube. 7

Accelerating structure components Internal cooling system: Cooling is integrated in AS-bar. Water out 1 Wg inputs 1 & 2 2 4 1 5 8 2 7 Water in BEA M Water in R. Nousiainen Water out 8

Accelerating structure components SAS is connected to RF-Loads, RF-network waveguides and central vacuum tank: RF-network waveguides connections RF-Load connections Central tank connections RF-Load connections 9
