Awake Electrons Gun Introduction. - How works an electrons gun - Required work - Input data Project - Modifications of vacuum chamber transfer - New frame - Wave Guide - Transport trolley for Transfer Chamber - Scintillator Conclusion

How works an electron gun: RF Gun & Accelerator Waves Guide Klystron Accelerator

How works an electron gun: Laser

How works an electron gun: Electrons Emission Cathodes in spares Transport Carrier Wave guide Cathode RF Gun Laser Soleinoid Mirror

How works an electron gun: Electrons Emission Cathodes in spares Transport Carrier Wave guide Cathode Canon RF Laser Soleinoid Mirror Electrons Beam

How works an electron gun: Cathodes & Transport carrier Manipulator Cathode: Copper Substratum: Cesium + Tellurium

Required work: Install in TCV4 cavern Electrons source and Wave Guide CTF2 Electrons Gun With vertical TC Shielding Awake Cavern TCV4

Required work: Install in TCV4 cavern Electrons source and Wave Guide CTF2 Electrons Gun With TC in vertical position Existing metallic structure

Required work: Install in TCV4 cavern Electrons source and Wave Guide Splitter CTF2 Electrons Gun With TC in horizontal position Wave guide elements

Input data Simplified model CTF2 Electrons Gun Some old drawings Electron Gun in operating in CTF2

Adaptation of the transfer vacuum chamber Chamber from CTF2 Flange for scintillator translator Flange for viewport Cut 4 flanges Cut bellows for UHV cleaning after machining and welding New flange and bellows Flange for Transport Carrier

New Frame Original Frame Assembled frame with positioning equipements Adjustable Base New Frame

Wave Guide 3Ghz Circulator Phase shifter Klystron Attenuator

Trolley for TC Transport TC in horizontal position, ready for the transfert on new Electron Gun frame Lifting winch for TC transfer Trolley from CTF2 with TC in vertilcal position

Scintillator for laser positioning Scintillator: Ceramic Al203 Cathode Translator Visible beam Ultraviolet Laser (invisible spectrum) Scintillator support Cathode manipulator ViewPort

Conclusion Very interesting project because it was complete and technologicaly diversified. - Vacuum :chamber, TC, Wave guide… - Welded structure: Trolley, Electron gun Frame. - RF: Wave guide. - Laser: Scintillator - Integration of all the equipments in Awake 3D model. - Modelization and CDD archiving of old documents. Good contacts and exchanges with many people for technical advices. - Eric Chevalley and Kevin Pepitone for explanations about the RF gun operation. - Emilien Rigutto and Thibaut Coiffet for the machining and reusing of the transfer chamber. - Nicolas Sebastien Chritin for his advices and for the liberty of work that he leaved to me.
