Development of RF Power System for PRAE Linac Project
Development of an RF power system for the PRAE Linac project, involves the support of RF power and RF distribution for SESAME program. The project includes sourcing power for the gun and accelerating structure modulator, construction and testing of modulator components, and simulation of modulator operations. The peak power, voltage, and current parameters are specified, along with details of the modulator composition and status updates on various project components. Progress is being made in various areas such as pulse transformer and tank implementation, auxiliary systems, and control mechanisms. The klystron and RF distribution aspects are also detailed, highlighting specific parameters and equipment used. The project schedule and conclusion outline the next steps in the project's construction phase.

Projet Emblmatique Programme SESAME With the support of RF Power & RF Distribution For PRAE Linac Maher OMEICH 08/10/2018 1
RF Power for Linac Source of power for Gun and Accelerating Structure Modulator / Klystron Home Made Modulator Recycling elements from SLAC CPI Klystron 2 phases for the Modulator : Construction and test in Hall LAGARRIGUE Transfer to PRAE site
Parameters RF Peak Power max.: 45 MW Peak Voltage max.: 310 kV Peak Current max.: 350 A Electrical Peak Power max.: 109 MW Pulse Width ( Voltage ): 6,5 S Rep. Rate: 50 Hz Delay Line type Modulator Thyratron switching system
Modulator Composition HV Power supply Up grade? Pulse Forming Network To be change to fit PRAE parameters Thyratron switch system Pulse Transformer, Tank & Tank auxiliary New pulse transformer, New Tank ? Auxiliaires Systems, control & measurement To be change to fit PRAE parameters Remote Control New Interface
Status Study & simulation of modulator : done Choise of emplacement for construction and test : Hall LAGARRIGUE Power and water to feed in place : not yet Recycling elements from SLAC : not yet Pulse transformer and Tank : in progress Auxiliaries systems : in progress Remote control : not yet
Klystron Klystron: VKS-8245C RF power(output): 45 MW RF power(input): 500 W Cathode Voltage: 305 kV Cathode Current: 340 A RF Pulse Width: 4,5 S Rep. Rate: 50 Hz Efficiency: 43 % Gain: 47 dB Perveance: 2, [ a/v ] High impedance Electromagnet 3/2
Status Scheduele
RF Distribution RF Distribution similar to ThomX (> Power) Use of elements from CERN ( Waveguides & Loads ) ALL other elements from Industrie
Conclusion Starting construction of the Modulator need: 1- Get the emplacement Hall LAGARRIGUE 2- Get elements from SLAC Power and water connections In progress: Pulse transformer & tank Auxiliaries systems Construction & test : 12 Months Manpower: 1 Enginneer + 1 Technicien
