DESIGNOFA VACUUM COAXIALLINEFOR ASTERIXTO STUDYTHE BEHAVIOR OFA MITLAT HIGHVOLTAGE

insulated regime is,underconstant voltage, stable and without anylosses. AT PEM (Polygoned'Experimentation de To study thebehavior ofthiskingoflineonthe Moronvilliers), theCEA willbuilda FlashX-Ray generator ASTERIX,CEA hasdecided toextend the generator based onLTDtechnology. Inthis machine, the present vacuumcoaxial line whichinner andouter radius electrical energy istransmitted totheX-raydiode bya areclose tothefinal LTDgenerator line.
