CONDITIONING OF PIECES FOR CLEANROOM

19/03/2014 Mathieu Therasse BE/RF/SRF

Baldaquin ISO5 in SM18 (for conditioning)

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

Cleanroom assembly SM18

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)


CAVITIES DELIVERY

19/03/2014

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.


COUPLER SYSTEM ASSEMBLY PROCEDURE

RF coupler line

Motor Control

UHV rotary motion

Rod

RF power coupler


UHV ROTARY MOTION FEEDTHROUGH INSTALLATION

19/03/2014

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

Installation on the top plate (for top plate leak test)

- 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

extension rod

ROTARY AXIS INSTALLATION ON THE CRYOMODULE

19/03/2014 Mathieu Therasse BE/RF/SRF

Preparation- Axis reception (+ support ring)- Degreasing (102bldg or 867bldg)- Conditioning in Baldaquin ISO5 in SM18 (alcohol and 2 plastic bags with N2 gas)

Procedure

- 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 Top view Screen

Support ring Bottom view


RF POWER COUPLER INSTALLATION

19/03/2014

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

Preparation- Mount the motor control in the baldaquin ISO5- Conditioning with 2 plastic bags with N2 gas

COUPLER MOTOR CONTROL INSTALLATION

19/03/2014 Mathieu Therasse BE/RF/SRF 9

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

Switch


PICK-UP INSTALLATION

19/03/2014

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

Axis

Lever arm


TUNER MOTOR INSTALLATION

19/03/2014

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

Preparation- Motor control reception- Conditioning with 2 plastic bags with N2 gas


TUNER AXIS INSTALLATION

Procedure- Pass the axis through the thermal screen from the bottom- Connect the second part of the axis to the tuner control

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


LEVER ARM INSTALLATION (I)

19/03/2014

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.

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 - Adjust position of levers and clevis at the rod and in the centre- Fix the screws and the counter screws to connect the rod

LEVER ARM INSTALLATION (II)


RF CABLES ASSEMBLY PROCEDURE

19/03/2014

Preparation- Cable reception from Huber and Suhner with connectors (N type, 7/16”) - UHV RF connector receipt from Hositrad Ceramtec cie, and Allectra- Leak detection on each connector- Cable testing (with Network analyser, attenuation…)- Conditioning cables and connectors with 2 plastic bags and N2 gas

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

N type double sided on CF 40 flange (Allectra)

7/16” double sided on CF 63 flange (Ceramtec)
