  2. OVERVIEW • CONDITIONING OF PIECES FOR CLEANROOM • CAVITIES DELIVERY • COUPLER SYSTEM ASSEMBLY PROCEDURE • TUNER SYSTEM ASSEMBLY PROCEDURE • RF CABLES ASSEMBLY PROCEDURE Mathieu Therasse BE/RF/SRF

  3. CONDITIONING OF PIECES FOR CLEANROOM Baldaquin ISO5 in SM18 (for conditioning) Cleanroom assembly SM18 • Piece preparation • - All piece has to be degreased • Before entering in baldaquin clean it with alcohol and blow with N2 gas • The person inside has to blow it with N2 gas • Clean it again inside the Baldaquin (with cleanroom cloth with alcohol) • Put it in 2 plastic bag (Antistatic and used for clean room) with N2 gas and close it • Before entering in ISO7 • Remove the first plastic bag • Blow it with N2 gas • Give it to the person inside the cleanroom (who blows the bag from inside to outside with N2 gas) • Open the last plastic just before installation Rmk: The person outside has to manipulate all piece with gloves (without powder) Mathieu Therasse BE/RF/SRF

  4. CAVITIES DELIVERY • Cavity storage: • Beamport support (installed before the RF test) • Tuning plate and tuning plate collar (installed before the RF test) • Special support for the multifunction trolley (installed after the RF test) • Beamport, pick-up and coupler protections (under design) • 2 plastic bags (antistatic, PEBP) with N2 gas Cavities will be stored in SM18 in ISO5 Baldaquin on a support trolley. Cavities will be transported between the baldaquin and the cleanroom with a special trolley. Mathieu Therasse BE/RF/SRF

  5. COUPLER SYSTEM ASSEMBLY PROCEDURE RF coupler line Motor Control UHV rotary motion Rod RF power coupler Mathieu Therasse BE/RF/SRF

  6. UHV ROTARY MOTION FEEDTHROUGH INSTALLATION Preparation - Reception of the UHV rotary motion from MDC Vacuum - Drilling of the rotary axis on the vacuum part and of the extension rod - Leak detection of the UHV rotary motion - Connection of extension rod and UHV rotary in the ISO5 baldaquin - Conditioning in double plastic bags (PEBP) with N2 gas feedthrough Installation on the top plate (for top plate leak test) extension rod • Clean (dust cloth and alcohol) and check (no particle, scratch) top flange and UHV Rotary motion knifes • Put the CF 40 copper gasket • Fix the UHV rotary motion Mathieu Therasse BE/RF/SRF

  7. ROTARY AXIS INSTALLATION ON THE CRYOMODULE • Preparation • Axis reception (+ support ring) • Degreasing (102bldg or 867bldg) • Conditioning in Baldaquin ISO5 in SM18 (alcohol and 2 plastic bags with N2 gas) Procedure Screen Support ring Top view • Pass the axis through the passive thermal screen from the bottom, and plug it to the UHV rotary motion axis (Hexagonal head). • Fix the support ring in order to maintain the rod on the passive screen (2 half rings). • The rod is supported by the thermal screen Support ring Bottom view Mathieu Therasse BE/RF/SRF

  8. RF POWER COUPLER INSTALLATION • Preparation • Coupler reception (Cold tested in SM18 vertical Test stand) • Conditioning in baldaquin • Procedure • Put the antenna all out (in order to protect it) • Put the Hexagonal head of the coupler in the cylindrical piece of the axis • Give an angle to the axis in order to pass the coupler through the support • Screw it on the cavity • Put the antenna ALL IN Mathieu Therasse BE/RF/SRF

  9. COUPLER MOTOR CONTROL INSTALLATION • Preparation • Mount the motor control in the baldaquin ISO5 • Conditioning with 2 plastic bags with N2 gas Switch • Procedure • Put the handle on the motor • Put the motor on the TOP switch position (antenna ALL IN) • Fix it on the UHV rotary motion (tighten the bellow and 4 screws) • Put the antenna ALL OUT (by hand with the handle) • Adapt the position of the BOTTOM switch (antenna ALL OUT) if it is necessary • Put the antenna all in Bellow Mathieu Therasse BE/RF/SRF

  10. PICK-UP INSTALLATION • Preparation • Reception of the antenna, copper extension, RF connector • Degreasing of each piece at the chemistry • Clean each part with alcohol, blow with N2 gas and do the assembly in baldaquin ISO5 in SM18 • Conditioning with 2 plastic bags with N2 gas Installation on the cryomodule - Fix the antenna on the cavity Mathieu Therasse BE/RF/SRF

  11. TUNER SYSTEM ASSEMBLY PROCEDURE Tuner line Motor control Axis Lever arm Mathieu Therasse BE/RF/SRF

  12. TUNER MOTOR INSTALLATION • Preparation • Motor control reception • Conditioning with 2 plastic bags with N2 gas • Procedure (top plate leak test) • Check that the motor is on the BOTTOM END switch (corresponding to the tuner plate flat position) + 6mm (6 turns) • Clean the knife with a dust cloth and alcohol • Check particle or default on motor and top plate knifes • Put a CF 63 copper gasket • Fix the motor on the top plate flange and screw it Mathieu Therasse BE/RF/SRF

  13. TUNER AXIS INSTALLATION • Preparation • - Reception of the 2 axis parts, 2 link motion • Degreasing • Assembly of the axis in baldaquin ISO5 • Conditioning with 2 plastic bags with N2 gas • Procedure • - Pass the axis through the thermal screen from the bottom • - Connect the second part of the axis to the tuner control Mathieu Therasse BE/RF/SRF

  14. LEVER ARM INSTALLATION (I) • Preparation • Reception of lever arm mechanism • Degreasing in Bldg 102 • Mounting and conditioning in baldaquin in SM18 • Conditioning in 2 plastic bags with N2 gas • Procedure • Put the central screw on the tuning plate and block it with a nut. • Fix the tuning mechanism to the tuning plate collar. Screw the grey part. Mathieu Therasse BE/RF/SRF

  15. LEVER ARM INSTALLATION (II) Procedure - Adjust position of levers and clevis at the rod and in the centre - Fix the screws and the counter screws to connect the rod Mathieu Therasse BE/RF/SRF

  16. RF CABLES ASSEMBLY PROCEDURE • Preparation • Cable reception from Huber and Suhner with connectors (N type, 7/16”) • UHV RF connector receipt from Hositrad Ceramteccie, and Allectra • Leak detection on each connector • Cable testing (with Network analyser, attenuation…) • Conditioning cables and connectors with 2 plastic bags and N2 gas N type double sided on CF 40 flange (Allectra) 7/16” double sided on CF 63 flange (Ceramtec) • Procedure • Clean and check connectors and top plate flanges knifes (dust, scratch) • Pass the cable through the thermal screen and connect it to RF connector on the top plate • Fix the insulating tube on the passive screen • Connect cables to the pick-up and the RF power coupler Mathieu Therasse BE/RF/SRF
