The fa­cil­ity is in­tended for SEE test­ing of mi­crochip, for pro­duc­tion of track mem­branes and for solv­ing of ap­plied physics prob­lems. The main sys­tems of DC140 are based on the DC72 cy­clotron ones that now are under re­con­struc­tion. The DC140 cy­clotron is in­tended for ac­cel­er­a­tion of heavy ions with mass-to-charge ratio A/Z within in­ter­val from 5 to 5.5 up to two fixed en­er­gies 2.124 and 4.8 MeV per unit mass. The in­ten­sity of the ac­cel­er­ated ions will be about 1 pmcA for light ions (A<86) and about 0.1 pmcA for heav­ier ions (A>132). The de­signed RF-sys­tem of the DC-72 cy­clotron with a half-wave cav­ity is not suit­able due to the big ver­ti­cal size. For this rea­son, a new quar­ter-wave RF-sys­tem was de­vel­oped for the DC140 cy­clotron pro­ject. The re­sults of cal­cu­lat­ing the pa­ra­me­ters of the new RF-sys­tem are given in this work.

  U400M isochro­nous cy­clotron was cre­ated on the base of U300 clas­sic cy­clotron and is under op­er­a­tion at FLNR, JINR since 1996. At the pre­sent time the cy­clotron elec­tro­mag­net with 4 meter pole di­am­e­ter needs a re­con­struc­tion that in­cludes a re­place­ment of mag­net main coil, cor­rec­tions of the mag­netic field at the cen­tral re­gion and at the ex­trac­tion ra­dius. For mea­sure­ments and shim­ming of cy­clotron mag­netic field the au­to­matic map­ping sys­tem, based on 14 Hall probes, will be cre­ated.

The de­sign and sim­u­la­tion of the beam trans­port sys­tem from cy­clotron is pre­sented in this re­port. The beam fo­cus­ing in the beam lines is pro­vided by set of quadru­pole lenses. The beam di­ag­nos­tics sys­tem con­sists of the Fara­day caps, lu­minophores and the mag­netic scan­ning sys­tem.

  The DC280 is the high cur­rent cy­clotron with de­sign beam in­ten­si­ties up to 10 pµA for ions with en­ergy from 4 to 8 MeV/nu­cleon. It was de­vel­oped and cre­ated at the FLNR JINR. The first was ex­tracted from the cy­clotron on Jan­u­ary 17, 2019. Ex­per­i­ments on ac­cel­er­a­tion of 12C, 40Ar, 48Ca, 48Ti, 52Cr and 84Kr beams pro­duc­tion were car­ried out. The fol­low­ing in­ten­si­ties of ac­cel­er­ated beam have been achieved: 10 pµA for 12C+2; 9,2 pµA for 40Ar+7; 7,1 pµA for 48Ca+10; 1,0 pµA for 48Ti+10; 2,4 pµA for 52Cr+10 and 1.43 pµA for 84Kr+14;. The ac­cel­er­a­tor has worked more than 9000 hours. The work of ac­cel­er­a­tor was sta­ble and high ef­fi­ciency. The total ac­cel­er­a­tion ef­fi­ciency from ion source to trans­port chan­nel was about 46%.
