TW attosecond X-Ray Pusel
ATTOSECond X-RayPulse LaserHamwe nububasha bukabije hamwe nigihe gito cyihuta ni urufunguzo rwo kugera ku ntsinzi idahwitse kandi x-ray itandukanye yerekana. Itsinda ryubushakashatsi muri Amerika ryakoresheje casade ya kabiriX-ray kubuntu electrongusohoka ku isonga ku isonga. Ugereranije na raporo zisanzwe, impuzandengo y'impinga y'impimbayo yiyongereyeho gahunda y'ubunini, imbaraga ntarengwa za Peak ni 1.1 TW, n'ingufu z'Abanzi bagera ku 100 μj. Ubushakashatsi butanga kandi ibimenyetso bikomeye kuri Soliton-nkimyitwarire yingengabihe muri X-ray.Abahigabatwaye ibintu byinshi bishya byubushakashatsi, harimo na fiziki yo murwego rwohejuru, intebe zifatika, kandi laser ibice byihuta. Mu bwoko bwose bwa laser, X-Imirasire ikoreshwa cyane mu kwisuzumisha kwa muganga, inzara zinganda, ubugenzuzi bw'umutekano n'ubushakashatsi mu bumenyi. X-ray kubuntu-electron laser (xfel) irashobora kongera imbaraga za peak X-ray. Attosecond iherutse gukorwa Xfel ni ikintu gikomeye cyagezweho muri siyanse n'ikoranabuhanga biboneka mu mafaranga arenga atandatu yubunini ugereranije ninteko ya X-ray.

Amashanyarazi ya electronirashobora kubona ingufu nyinshi zitanga ubunini burenze urwego rwigihe cyo kwisiga ukoresheje ihungabana rusange, riterwa no gukorana imirasire yumuhoro muri Shoreting Traam na Magnetic Osillator. Muburyo bwa X-ray (hafi 0.01 nm kugeza 0.1 nm uburebure), fel bigerwaho na bundle compressions hamwe na tekinike yo kugaburira. Muburyo bworoshye x-ray (hafi 0.1 nm kugeza 10 muburebure bwa 10), fel irashyirwa mubikorwa na cascade tekinoroji nziza. Vuba aha, Attosecond Pulses hamwe nimbaraga za fuak ya GW 100 GW byatangajwe no gukoresha uburyo bworoshye bwo kwikuramo imyuka (Esase).

Itsinda ryubushakashatsi ryakoresheje sisitemu yintambwe ebyiri ikubiyemo Xfel kugirango yongere X-ray attosecond Pulse Ibisohoka biva muri liyontInkomoko yorohejeKuri TW TW, gahunda yubunini bwo kunoza ibisubizo byatangajwe. Gukora ubushakashatsi bwerekanwe ku gishushanyo cya 1. Ukurikije uburyo bwa SSOSE, ETHECTHede ETHINTER yo kubona urumuri rwa electron hamwe na spike ndende, kandi ikoreshwa mu kubyara attosecond X-Ray Pulses. Ibihe byambere biherereye kuruhande rwimbere ya spike ya electron, nkuko bigaragara hejuru yibumoso bwishusho. Hanyuma, umuganga wa kabiri wa magnetic ikoreshwa kugirango arusheho kwishura x-ray binyuze mumikoranire ya Athtesecond Pulses hamwe nigice gishya.

Igishushanyo 1 Igikoresho cy'ibikoresho; Ikigereranyo cyerekana umwanya wa kirerure (igishushanyo-cyingufu cya electron, icyatsi), umwirondoro wubu (ubururu), nimirasire yakozwe nuburenganzira bwambere (ibara ry'umuyugubwe). XTCAV, x-band ihinduranya inkumi; cvmi, amakarita yihuta yihuta yerekana sisitemu; FZP, Fresnel BAND Platrometer

Athtesecond yose yubatswe ku rusaku, bityo buri shoferi afite imitungo itandukanye kandi ifite igihe ntarengwa, abashakashatsi bashakishaga muburyo burambuye. Kubijyanye na Spectra, bakoresheje amafoto ya Freslande kugirango bapime specrate yumuntu ku giti cyabo ku burebure butandukanye ndetse na nyuma yo kongera ubwato bwabatandukanya ndetse na nyuma yo kongeramo. Mugihe domeni, inguni impande zapimwe nigihe cya domeni yatutse kwihuta irangwa. Nkuko bigaragara ku gishushanyo cya 1, x-ray pulse yuzuyemo umuzenguruko wa feri ya Laser pulse. Phosefectrons Ioselecks na X-ray pulse izatanga imirongo mu cyerekezo gitandukanye na vector ubushobozi bwa laser ya infrared. Kuberako amashanyarazi ya laser azenguruka hamwe nigihe, gukwirakwiza somem ya mafotoron, hamwe nubusabane hagati yigihe cyo kuvuza nigihe cyo gukwirakwiza umubumbe. Ikwirakwizwa ryimbaraga za Phosefectrom ryapimwe ukoresheje amashusho yihuse yerekana amashusho. Ukurikije kugabura no gutangaza ibisubizo, igihe-kirumuriro cya terefone ya Attosecond irashobora kubakwa. Igishushanyo 2 (a) cyerekana ikwirakwizwa ryigihe kinini, hamwe na 440 nka. Hanyuma, gahunda yo gukurikirana gaze yakoreshejwe mugupima ingufu za pulse, kandi umugambi wo gutatanya hagati yimbaraga za peak pulse nibihe nkuko bigaragara ku gishushanyo cya 2 (B) cyarabazwe. Iboneza bitatu bihuye nibitekerezo bitandukanye bya Electron Kwibanda, have hoza ibisabwa na compressor ya magnetique itara. Imboneko eshatu zatanze impuzandengo igereranya pusgies yo mu 150, 200, na 260 μj, ku buryo, ifite imbaraga nyinshi za 1.1 TW.

Ishusho ya 2. .

Byongeye kandi, ubushakashatsi bwarubahirije bwa mbere phenomenon ya Soliton-nka Super-SUPred mumatsinda ya X-Ray, bigaragara ko bigabanuka cyane mugihe cyongeraho. Biterwa n'imikoranire ikomeye hagati ya electron n'imirakari, hamwe n'ingufu bimuriwe vuba na Electron kugera ku mutwe wa X-Ray Pulse hamwe na electron uhereye ku murizo. Binyuze mu bushakashatsi bwimbitse kuri iki kibazo, biteganijwe ko X-ray impimusi hamwe nigihe gito hamwe nimbaraga nyinshi zo kwishyurwa no kwifashisha imikorere ya superradiation no gukoresha igabanya molse muri societe soliton-nkuburyo.
