Method of extracting charged particles from an isochronous cyclotron and device in which this method is applied

摘要

EXTRACTION OF A BEAM PARTICLE LOADED a cyclotron isochronous (1) comprising an electromagnet constituting the magnetic circuit including at least a number of sectors (3, 3) KNOWN HILLS, IN WHICH THE AIR GAP IS REDUCED, SEPARATED BY SECTORS shaped spaces (4) VALLEYS CALLED THE DIMENSION WHERE AIR GAP IS GREATER; The extraction method is characterized in that the particle beam removed without recourse to a EXTRACTION, THANKS TO A PARTICULAR DISPOSITION OF MAGNETIC FIELD OBTAINED DESIGNING THE AIR GAP OF IMAN IN THE HILLS (3, 3) Cyclotron Isochronous SO THE RELATIONSHIP BETWEEN THE MAGNET DIMENSION OF AIR GAP IN THE HILLS, CLOSE TO THE MAXIMUM RADIO, RADIO AND GAIN BACK FOR PARTICLE accelerated by the cyclotron within that radius, is less than 20.
