  This paper con­sid­ers the ap­pli­ca­tion pack­age that sim­u­lates trans­port chan­nel of rel­a­tivis­tic charged par­ti­cles. The pack­age pro­vides an in­ter­ac­tive mode for the user. It is pos­si­ble to ob­serve the main pa­ra­me­ters of the beam cross­ing the chan­nel on the PC screen such as en­ve­lope and cross-sec­tion of the beam at dif­fer­ent sec­tions of the chan­nel while chang­ing the main con­trol pa­ra­me­ters of the real chan­nel. En­abling of pro­ce­dures of math­e­mat­i­cal pro­gram­ming pro­vides ex­press op­ti­miza­tion of con­trol pa­ra­me­ters of the chan­nel. The de­signed pack­age is com­pact, has a mod­u­lar struc­ture and can be eas­ily adapted to dif­fer­ent soft­ware plat­forms. MAT­LAB in­te­grated en­vi­ron­ment is used as in­stru­men­tal en­vi­ron­ment, which has a free­ware ver­sion of this sys­tem - SCILAB. Pack­age test­ing was car­ried out on the elec­tron syn­chro­tron "Pakhra" dur­ing the re­cal­i­bra­tion of the chan­nel of the ac­cel­er­a­tor work­ing in dif­fer­ent modes, which are de­ter­mined by con­ducted ex­per­i­ments.

  The re­port con­sid­ers the in­ter­ac­tive com­puter mod­el­ing of vac­uum sys­tems. Op­er­a­tion of real vac­uum in­stal­la­tions is mod­eled by sim­u­lat­ing com­puter code. It be­comes pos­si­ble in a short time (with the as­sess­ment of real-time) to pass through full cycle of the tech­nolo­gies to reach high vac­uum state and to es­ti­mate the nec­es­sary time. It is pos­si­ble to as­sem­ble vir­tual in­stal­la­tion, to choose the nec­es­sary pumps (from the data­base of low-vac­uum and high-vac­uum ones), to se­lect the vac­uum con­nect­ing pipes with the re­quired pa­ra­me­ters. The vac­uum cham­ber vol­ume and its in­ter­nal sur­faces char­ac­ter­is­tics (rough­ness, types of pre­lim­i­nary pro­cess­ing), defin­ing out­gassing from these sur­faces are set. Pos­si­ble leak­age in junc­tion places of the in­di­vid­ual el­e­ments of the sys­tem could be taken into con­sid­er­a­tion. After pump­ing start, se­quen­tial switch­ing on of dif­fer­ent pumps and achieve­ment of a cer­tain pres­sure, pos­si­bil­ity of cham­ber pre­heat­ing up to the nec­es­sary tem­per­a­ture is pro­vided. Dur­ing the analy­sis of pro­ce­dure of pump­ing op­ti­miza­tion of the struc­ture of sys­tem and the se­lected el­e­ments is made. The com­puter lab­o­ra­tory is a part of tra­di­tional lab­o­ra­tory of vac­uum tech­nique of the De­part­ment of Elec­tro­phys­i­cal Fa­cil­i­ties of NRNU MEPhI.

  Key­words: dou­ble form­ing line (DFL), com­pres­sor mi­crowave pulses, mi­crowave plasma dis­charger, res­onator – stor­age, input power de­vice (an input power), en­ergy out­put de­vice. The first part is de­voted to the cal­cu­la­tion and de­sign com­pres­sor using a sin­gle-mode wave­guides. We in­ves­ti­gated the processes of ac­cu­mu­la­tion and en­ergy ex­trac­tion from the res­onator – stor­age of com­pres­sor, the de­pen­dence of the ef­fi­ciency of en­ergy ex­trac­tion from the com­pres­sor on the plasma pa­ra­me­ters of the dis­charge gap: n, q, m, v, r, h - the con­cen­tra­tion, charge, mass, the fre­quency of col­li­sions of free elec­trons, the ra­dius and height of the cylin­der through which flows the dis­charge. Re­fine­ment con­struc­tion site en­ergy out­put and its op­ti­miza­tion, match­ing wave­guide res­onator - drive to the wave­guide load in de­riv­ing en­ergy from the com­pres­sor mi­crowave was pro­duced. The con­cept of a multi-com­pres­sor DFL was pro­posed and op­ti­miza­tion under axial field was make to in­crease the di­elec­tric strength and re­duce the in­duc­tance of the dis­charge gap. In the sec­ond part of the paper ques­tions, the de­sign of the com­pres­sor DFL on over­sized wave­guides with work­ing mode H01n was dis­cusses. New con­struc­tions of power input de­vices was pro­pose that allow not only to pro­vid­ing the nec­es­sary cou­pling co­ef­fi­cient with the feed path, but also greatly re­duced the ex­ci­ta­tion of un­ac­cept­able modes in the res­onator – stor­age.

Re­sults of study en­ergy ex­trac­tion de­vices for S-band mi­crowave pulse com­pres­sors are pre­sented. The de­vices are man­u­fac­tured as in­ter­fer­ence switches pro­duced from the cir­cu­lar sin­gle mode wave­guide and that are dif­fers only by the cas­cade of iden­ti­cal H-plane T-junc­tions con­nected in se­ries at a side arm of H-tee. The ver­sions cas­cade switches which are matched and un­matched from the side of aux­il­iary arm of T-junc­tion are in­ves­ti­gated. It is shown the vari­ant of cas­cade switches with the matched T-junc­tions al­lows de­crease the switch­ing power level few times com­par­a­tively the switch­ing power of usual one. Pos­si­bil­ity of in­creas­ing op­er­a­tion power and sta­bil­ity of out­put pulses of mi­crowave pulse com­pres­sors with such en­ergy ex­trac­tion de­vices are con­firmed in ex­per­i­ments. There are pre­sented the re­sults of in­ves­ti­ga­tion the cas­cade in­clud­ing two and three switches con­nected in se­ries by straight arms. It is shown the switch­ing power level for such type cas­cade switches can be many less than for usual switch with one T-junc­tion. Re­sults of ex­per­i­men­tal study cas­cade switches of such type con­firm­ing with the re­sults of the the­o­ret­i­cal analy­ses are pre­sented and pe­cu­liar­i­ties of cas­cade switches are men­tioned. The as­sump­tion about good per­spec­tives for the cas­cade switches man­u­fac­tured from over­sized rec­tan­gu­lar wave­guide is for­mu­lated. The ob­tained re­sults con­cern­ing of the cas­cade switch op­er­a­tion have been demon­strated the pos­si­bil­ity of in­creas­ing switch op­er­a­tion power.

Re­sults of sim­u­la­tion and ex­per­i­men­tal study of two types of the over­sized in­ter­fer­ence switches are pre­sented. The switch of the first type was de­vel­oped on basis of the sim­u­la­tion of the over­sized rec­tan­gu­lar wave­guide H-tee with the H01 op­er­a­tion mode. Con­di­tions of ef­fec­tive op­er­a­tion of the first type switch as an en­ergy ex­trac­tion el­e­ment of ac­tive mi­crowave pulse com­pres­sors are de­ter­mined. The out­put pulse power of 2.8 MW and pulse width of 3.5 ns with the cor­re­spond­ing am­pli­fi­ca­tion fac­tor of 17.5 dB for were ob­tained in the X-band mi­crowave pulse com­pres­sor pro­to­type con­tain­ing the stor­age cav­ity made of WR-284 wave­guide and the switch made of the wave­guide with the cross sec­tion area of 58×25 mm2. The re­sults of ex­per­i­men­tal study of the over­sized X-band in­ter­fer­ence switch of the sec­ond type with the syn­chro­nous en­ergy ex­trac­tion through a com­pact packet of com­mon sin­gle mode switches in­cor­po­rat­ing the five iden­ti­cal wave­guide tees are pre­sented as well. Pos­si­bil­ity of full syn­chro­niza­tion of the switch packet is proved and the con­di­tions of such syn­chro­niza­tion are de­ter­mined. Per­mis­si­ble quan­tity of the switches in a packet unit is es­ti­mated. The out­put pulse power of 0.8 MW, pulse width of 3.2 ns at the power gain of 12 dB and the pulse power of 2.2 MW, pulse width of 3.5 ns at the power gain of 16.5 dB were ob­tained when the en­ergy ex­trac­tion from the five dif­fer­ent sin­gle mode res­o­nant cav­i­ties and an over­sized cav­ity re­spec­tively was syn­chro­nous.

  DC-60 heavy ion ac­cel­er­a­tor, put into op­er­a­tion in 2006, ac­cord­ing to its spec­i­fi­ca­tions - spec­trum, charge and en­ergy of ac­cel­er­ated ions, has the high sci­en­tific, tech­no­log­i­cal and ed­u­ca­tional po­ten­tial. The high­est pos­si­ble uni­ver­sal­ity both by spec­trum of ac­cel­er­ated ions and ac­cel­er­a­tion en­ergy and regimes was built in DC-60 heavy ion ac­cel­er­a­tor de­sign­ing. The new in­ter­dis­ci­pli­nary re­search com­plex based on cy­clotron DC-60 makes it pos­si­ble to cre­ate a highly-de­vel­oped sci­en­tific-tech­no­log­i­cal and ed­u­ca­tional en­vi­ron­ment in the new cap­i­tal of Kaza­khstan. DC-60 ac­cel­er­a­tor is a dual cy­clotron, which is ca­pa­ble of charged par­ti­cles ac­cel­er­a­tion up to ki­netic en­er­gies in MeV/nu­cleon, ex­pressed in the fol­low­ing re­la­tion: E = 60(zi/A)2, where zi - ac­cel­er­ated ion charge, A - atomic weight of ion. Re­la­tion (zi/A) in for­mula must be within the fol­low­ing lim­its: (zi/A)2 = (1/6 – 1/12), that im­pose con­straints on charge of ac­cel­er­ated ions. Thus, range of ions ac­cel­er­ated on DC-60 cy­clotron is 6Li to 132Xe, vari­a­tion of ion en­ergy is over the range 0.33 to 1.75 MeV/nu­cleon. Some re­sults of our work car­ry­ing out on the base of DC-60 cy­clotron in the field of pro­duc­tion, ac­cel­er­a­tion and trans­porta­tion of charged par­ti­cles, physics of solid state, nu­clear and atomic physics, pro­duc­tion of track mem­branes etc are given in the ar­ti­cle. Also it will be re­ported about mod­ern trends of ac­cel­er­a­tors de­vel­op­ment in Kaza­khstan.

  There are two RFQ DT pro­ton linacs, named the LU-30 and LU-30M, in the SRC IHEP of NRC "Kur­cha­tov In­sti­tute" that are presently in op­er­a­tion. Both are the unique ma­chines em­ploy­ing ra­dio-fre­quency quadru­pole fo­cus­ing up to 30 MeV at exit. The LU-30 ma­chine now runs as a pro­ton in­jec­tor to the booster RC PS U-1.5 that feeds the main PS U-70 ul­ti­mately. The LU-30M is now run in a stand-alone test op­er­a­tion mode. Such a par­al­lel func­tion­ing of these two ac­cel­er­a­tors al­lows to use the LU-30M as an ex­per­i­men­tal fa­cil­ity en­abling R&D on new tech­ni­cal de­ci­sions and up­grades for the age­ing LU-30. On the other hand, the rou­tine op­er­a­tion of the work­horse LU-30 al­lows for test­ing of the tech­ni­cal de­ci­sions pro­posed under a heavy non-stop op­er­a­tion dur­ing the U-70 runs for fixed-tar­get physics.

  The re­port de­scribes the re­sults of the de­vel­op­ment and test­ing of the Elec­tron-23high-volt­age high-power elec­tron ac­cel­er­a­tor rated for an ac­cel­er­at­ing volt­age of 1 MV and beam power up to 500 kW at the "NI­IEFA" test­ing fa­cil­i­ties. The ac­cel­er­a­tor is in­tended for in­dus­trial pro­cess­ing of flue gases from coal burn­ing ther­mal power sta­tions with the aim to re­duce con­cen­tra­tions of ni­tro­gen and sul­fur ox­ides. The ac­cel­er­a­tor may also be used for other en­ergy-con­sum­ing processes, such as ra­di­a­tion treat­ment of waste­water for the pur­pose of their de­con­t­a­m­i­na­tion or pro­cess­ing of nat­ural gases for their con­ver­sion into en­gine fuel. The re­port de­scribes the main com­po­nents and sys­tems of the ac­cel­er­a­tor, such as the high-volt­age gen­er­a­tor, the ac­cel­er­at­ing volt­age reg­u­la­tion de­vice, the elec­tron-op­ti­cal sys­tem, the elec­tron source and the ac­cel­er­at­ing tube, the ir­ra­di­a­tion field form­ing sys­tem, the beam out­put de­vice and vac­uum sys­tem.

De­vel­oped in BINP wide­band beam po­si­tion mon­i­tor (BPM) elec­tron­ics has been in­stalled at the VEPP-4M elec­tron-positron col­lider. The VEPP-4M op­er­ates with two elec­tron and two positron bunches. Wide band­width of new elec­tron­ics (200 MHz) al­lows the sep­a­rate mea­sure­ments of elec­tron and positron bunches with time in­ter­val be­tween bunches up to 18 ns. 18 BPMs lo­cated near four meet­ing points are sup­plied with new elec­tron­ics. The elec­tron­ics can mea­sure the po­si­tion of each of four bunches. BPM sys­tem works at two modes: slow closed orbit mea­sure­ments and turn-by-turn mea­sure­ments. We pre­sent de­tails of sys­tem de­sign and op­er­a­tion.

  The media server was de­vel­oped that im­ple­ments the ex­change of video and audio streams be­tween con­trol rooms for U-70 tech­no­log­i­cal sub­sys­tems. Media server has the pos­si­bil­ity of mak­ing changes into the in­ter­me­di­ate video im­ages to embed cur­rent tech­no­log­i­cal in­for­ma­tion. The media server is im­ple­mented as a set of threads of ex­e­cu­tion, one for each video for­mat con­ver­sion mod­ule. The media server is a chain of suc­ces­sive trans­for­ma­tions of video and audio streams from one for­mat to an­other: H264 - Y4M - The­ora for­mats for video, PCM - Vor­bis for­mats for audio. The final video and audio streams are en­cap­su­lated into the OGG con­tainer stream which is trans­lat­ing into the local net­work. OGG con­tainer has been cho­sen be­cause of its com­pletely open, patent-free tech­nol­ogy and full sup­port in HTML5. Any Web browser with full HTML5 sup­port may be used as OGG stream con­sumer. The browser client pro­gram has writ­ten with tag "video" uti­liza­tion. This al­lows for client to work on dif­fer­ent plat­forms (Linux, Win­dows) and get rid of third-party video plug-ins.
