  The pro­ject NICA is being con­structed in JINR, Dubna to pro­vide col­li­sions of heavy ion beams in the en­ergy range from 1 to 4.5 GeV/u at the lu­mi­nos­ity level of 1*1027 cm-2*s−1. One of the el­e­ments in the col­lider in­jec­tion chain is BUSTER – a cy­cling ac­cel­er­a­tor of ions 197Au32+. The in­jec­tion en­ergy of par­ti­cles is 6.2 MeV/u, ex­trac­tion en­ergy is 600 MeV/u. Two RF sta­tions are to pro­vide 10 kV of ac­cel­er­a­tion volt­age. Fre­quency range of op­er­a­tion of the sta­tions in the in­jec­tor chain is from 634 kHz to 2400 kHz. The pro­vi­sions are made for au­tonomous mode of op­er­a­tion of the sta­tions in the fre­quency range of 0.5 – 5.5 MHz at the same ac­cel­er­at­ing volt­age. Amor­phous metal rings of Russ­ian pro­duc­tion are used in the RF cav­i­ties. RF sta­tions are cre­ated in the Bud­ker In­sti­tute of Nu­clear Physics, SB RAS, Novosi­birsk. The sta­tions are tested in the op­er­a­tive mode and will be de­liv­ered to the cus­tomer in Oc­to­ber, 2014. Main de­sign fea­tures and pa­ra­me­ters of RF cav­ity, power gen­er­a­tor and con­trol sys­tem of the sta­tions are de­scribed in the paper.

  The geom­e­try of the in­duc­tion elec­tron ac­cel­er­a­tor, which will be used for high cur­rent ac­cel­er­a­tion, has been cal­cu­lated. For the dif­fer­ent cur­rents val­ues the op­ti­mum fo­cus­ing mag­netic field and has been ob­tained. Also a cur­rent in the com­pen­sative coil near the cath­ode has been cal­cu­lated. The cath­ode elec­trode geom­e­try was chang­ing to achieve min­i­mum beam os­cil­la­tions dur­ing the ac­cel­er­a­tion.

  A de­sign and de­vel­op­ment of a linac front-end, that guar­anties the re­quired beam, qual­ity is an issue of the day. A linac with RF fo­cus­ing by means of the ac­cel­er­at­ing field spa­tial har­mon­ics is sug­gested as an al­ter­na­tive to RFQ sys­tem. Sim­u­la­tion re­sults of the low-en­ergy pro­ton beam dy­nam­ics at linac, that takes into ac­count main linac pa­ra­me­ter op­ti­miza­tion, based on ad­vanced dy­nam­i­cal ac­cep­tance cal­cu­la­tion, are pre­sented and dis­cussed.

Meth­ods of beam dy­nam­ics op­ti­miza­tion of the first order are known and used for beam dy­nam­ics op­ti­miza­tion*. These method are based on nu­mer­i­cal cal­cu­la­tion of gra­di­ent of func­tional es­ti­mat­ing beam qual­ity. In this re­port, method of op­ti­miza­tion is pro­posed that in­cludes nu­mer­i­cal cal­cu­la­tion of the sec­ond de­riva­tions (Hes­s­ian) of the qual­ity func­tional. Pro­posed method is ap­plied for a beam in RFQ chan­nel. Con­trol prob­lem is for­mu­lated. The prop­blem con­sists in min­i­miz­ing of func­tional de­pend­ing on the beam den­sity and on con­trol func­tions. The con­trol func­tions are the ac­cel­er­a­tion ef­fi­ciency, the syn­chro­nous phase, and the chan­nel ap­per­ture. For nu­mer­i­cal so­lu­tion the con­trol func­tions are taken in pa­ra­me­ter­ized form. The process of op­ti­miza­tion rep­re­sents a se­quence of steps with use of the first and the sec­ond de­riv­a­tives on pa­ra­me­ters, dur­ing which the value of the func­tional de­creases.

  Elec­tron cool­ing sys­tem (ECS) of the NICA col­lider is de­signed to form the re­quired pa­ra­me­ters of the ion beam at en­ergy of the ex­per­i­ment in the range of 1 - 4.5 GeV/amu that re­quires en­ergy cool­ing elec­trons from 0.5 to 2.5 MeV. To achieve the re­quired en­ergy of the elec­trons all el­e­ments of ECS are placed in tanks filled with sul­fur hexa­flu­o­ride (SF6) under pres­sure of 6 atm. For test­ing items ECS el­e­ments the test bench "Re­cu­per­a­tor" is used. This paper pre­sents the re­sults of test­ing the pro­to­type el­e­ments of the ECS and the first re­sults of tech­ni­cal de­sign of ECS.

  One of the prob­lems aris­ing at ex­trac­tion of heavy ions from plasma is re­moval of elec­trons from a stream of par­ti­cles. There­fore pos­si­bil­ity of si­mul­ta­ne­ous ac­cel­er­a­tion in one di­rec­tion as ions (elec­tric field), and elec­trons (pres­sure gra­di­ent) is rep­re­sented rather in­ter­est­ing. In work when using the hy­dro­dy­namic de­scrip­tion in the ac­cel­er­at­ing in­ter­val con­di­tions of cold ions and hot elec­trons are stud­ied. Pos­si­bil­ity of ex­cess by ions of speed of an ionic sound is shown, and the ratio of sizes of streams of be any.

  In the Lab­o­ra­tory of nu­clear re­ac­tions JINR ded­i­cated ac­cel­er­a­tor com­plex on the basis of the heavy ion cy­clotron DC110 for the in­dus­trial track mem­brane pro­duc­tion has been de­vel­oped and cre­ated. The isochro­nous cy­clotron DC110 ac­cel­er­ates the ions Ar, Kr and Xe with a fixed en­ergy of 2.5 MeV/nu­cleon and in­ten­sity of 10-15 mkA. The cy­clotron is equipped with ECR ion source - DE­CRIS-5 (18 GHz) and axial in­jec­tion sys­tem. The pole di­am­e­ter of the mag­net is 2 m. Isochro­nous mag­netic field formed by shim­ming sec­tors on the level of 1.67 T. Ac­cel­er­ated ions 40Ar6+, 86Kr13+, 132Xe20+ have close mass-to-charge ratio, which al­lows chang­ing par­ti­cles with­out chang­ing the op­er­a­tion mode of the cy­clotron. Ac­cel­er­a­tor com­plex DC-10 is ca­pa­ble of pro­duc­ing up to 2 mil­lion square me­ters of track mem­branes per the year.

WEPSB04 Field Optimization Technique of the Multigap H-mode Resonators impedance, cavity, linac 162
 
  • S.E. Toporkov, A.B. Buleiko, M.V. Lalayan
    MEPhI, Moscow, Russia
  
  Op­ti­miza­tion of the H-mode res­onators re­quires uni­form ac­cel­er­at­ing field dis­tri­b­u­tion on its axes. To re­al­ize this task py­lons with the holes on its end walls are used in many cases. Dur­ing ap­ply­ing this tech­nique in case of cav­i­ties with low num­ber of pe­ri­ods it was men­tioned that the best value of the field flat­ness was ob­tained in case of zero gap be­tween end walls of the res­onator and the pylon. It means that each pylon has got the elec­tri­cal con­tact with one of the end walls of the res­onator. For such cav­ity geom­e­try mag­netic field dis­tri­b­u­tion dif­fers from the clas­si­cal H – res­onator: it trans­forms in one com­mon mag­netic flux like in split-coax­ial cav­i­ties. The analy­sis of such struc­tures was per­formed for two types of H-mode res­onators: Cross bar H-mode (CH) res­onators with work­ing fre­quency 324MHz and In­ter­dig­i­tal H-mode (IH) res­onators with work­ing fre­quency 162MHz. All types of res­onators work on the pi-mode and have 9 ac­cel­er­at­ing gaps. The main stages of E-field flat­ness op­ti­miza­tion in­side CH− and IH− cav­i­ties are pre­sented at this paper.  
 
WEPSB05 Optimization of Electric Field Distribution Inside Multi-gap CH-Resonator impedance, cavity, proton, rfq 164
 
  • S.E. Toporkov
    MEPhI, Moscow, Russia
  
  This paper pre­sents the re­sults of the elec­tro­dy­namic mod­el­ling of the Cross­bar H-mode (CH) res­onator. The main goal was to get the uni­form ac­cel­er­at­ing field dis­tri­b­u­tion and to op­ti­mize ef­fec­tive shunt im­ped­ance. The ini­tial model of the 324 MHz cav­ity con­sists of 7 equidis­tant RF gaps with the pe­riod length 46.26 mm. To op­ti­mize its elec­tro­dy­namic char­ac­ter­is­tics the de­sign con­tains py­lons. So­lu­tion of the tun­ing task con­sists of sev­eral steps. Firstly it was cho­sen the op­ti­mal re­la­tion be­tween the hold­ing rod length and the pylon's height. Then the most sig­nif­i­cant im­prove­ment on the E-field dis­tri­b­u­tion was in­tro­duced by op­ti­miz­ing the gap be­tween end walls of the res­onator and the pylon. The final ad­just­ment of the field dis­tri­b­u­tion and the tun­ing to the work­ing fre­quency was per­formed by means of the holes in the pylon. Cor­rect geom­e­try in­creases ef­fec­tive shunt im­ped­ance from 55 MOhm/m to 80 MOhm/m and im­proves the field flat­ness to the 97%. The re­sults of op­ti­miza­tion the cav­i­ties for dif­fer­ent par­ti­cle ve­loc­i­ties with 7,9 and 11 ac­cel­er­at­ing gaps and dif­fer­ent aper­ture di­am­e­ter are pre­sented.

  The Vac­uum In­su­lated Tan­dem Ac­cel­er­a­tor is built at the Bud­ker In­sti­tute of Nu­clear Physics.* The ac­cel­er­a­tor is de­signed for de­vel­op­ment of the con­cept of ac­cel­er­a­tor-based boron neu­tron cap­ture ther­apy of ma­lig­nant tu­mors in the clinic.** In the ac­cel­er­a­tor the neg­a­tive hy­dro­gen ions are ac­cel­er­ated by the high volt­age elec­trode po­ten­tial to the half of re­quired en­ergy, and after con­ver­sion of the ions into pro­tons by means of a gas strip­ping tar­get the pro­tons are ac­cel­er­ated again by the same po­ten­tial to the full beam en­ergy. A num­ber of in­no­v­a­tive ideas posited in the de­sign make it pos­si­ble to ac­cel­er­ate in­tense beams in a com­pact ac­cel­er­a­tor. Num­ber of in­ves­ti­ga­tions re­vealed weak points of the ac­cel­er­a­tor in­jec­tor: un­nec­es­sary beam strip­ping by the resid­ual gas and com­plex­ity to im­prove the vac­uum con­di­tions, the in­flu­ence of the strip­ping gas to the ion source op­er­a­tion sta­bil­ity. To en­sure the beam pa­ra­me­ters and re­li­a­bil­ity of the fa­cil­ity op­er­a­tion re­quired for clin­i­cal ap­pli­ca­tions, the new in­jec­tor is de­signed based on the ion source with a cur­rent up to 15 mA, pro­vid­ing the pos­si­bil­ity of pre­lim­i­nary beam ac­cel­er­a­tion upto 120-200 keV.

  In this re­port pos­si­bil­ity of cyclic ac­cel­er­a­tion of the charged par­ti­cles in con­stant in time a mag­netic field is dis­cussed. The closed orbit of par­ti­cles is formed by a set of mag­netic dipoles. In each sec­tion of dipoles the ra­dial dis­per­sion of tra­jec­to­ries of a beam de­pends on the az­imuthal length of a di­pole and has the small size (on the order of sev­eral cen­time­ters). As the di­pole sec­tion has ra­dial fo­cus­ing and ver­ti­cal de­fo­cus­ing, using quadru­pole lenses be­tween di­pole sec­tions it is pos­si­ble to or­ga­nize al­ter­nat­ing-sing fo­cus­ing on all perime­ter of the ac­cel­er­a­tor. Par­ti­cles are ac­cel­er­ated by elec­tric field of the in­duc­tion sec­tions which pow­er­ing up is made at bunch ap­proach. The in­duc­tor of sec­tions are re­mag­ne­tized in the range of time be­tween a beam bunches. Sta­bil­ity of lon­gi­tu­di­nal os­cil­la­tions is de­fined by a form of a table of ac­cel­er­at­ing in­duc­tion pulses. Such ac­cel­er­a­tor is able to af­ford to ex­pand the range of pa­ra­me­ters of ac­cel­er­ated par­ti­cles on their charge and atomic weight as doesn't de­mand com­pli­ance of a res­o­nance of HF-sys­tem to the fre­quency of the cir­cu­lar fre­quency of ac­cel­er­ated par­ti­cles.
