Didþiausiais ir brangiausiais eksperimentas

[Minerva]

Dr. Èeslovas Ðimkevièius. "Startuoja didþiausias ir brangiausias eksperimentas istorijoje"

Rugsëjo 10 dienà prasideda pats didþiausias, pats brangiausias, o galbût, kaip teigia nemaþai skeptikø, ir pats baisiausias eksperimentas pasaulyje. Europos branduoliniø tyrimø centras (CERN – Conseil Europeen pour la Recherche Nucleaire) paskelbë, kad ðià dienà bus atliktas bandomasis dviejø protonø srautø susidûrimas Didþiajame hadronø kolaideryje – LHC (Large Hadron Collider). Tiesa, reikia pabrëþti, kad árenginys buvo ájungtas jau praëjusiø metø vasarà, bet tiek laiko reikia, kad jis pasiektø darbiná reþimà. Sunku net ásivaizduoti ðio árenginio mastà. Tai pats didþiausias kada nors þmonijos sukurtas eksperimentinis árenginys. Jis sumontuotas po þeme 100 metrø gylyje netoli Þenevos ir yra 27 kilometrø ilgio tunelis, kuriuo beveik ðviesos greièiu lëks du protonø srautai prieðprieðiais giliame vakuume ir beveik absoliutinio nulio temperatûroje (1,9 K arba -271,4 0C ). Todël aiðku, kodël tiek daug laiko reikia, kad árenginys bûtø parengtas darbui: ásivaizduokite kiek reikia skysto helio, norint pasiekti tokià þemà temperatûrà. Þema temperatûra reikalinga palaikyti superlaidþioje bûsenoje galingus magnetus, kurie ir priverèia protonus judëti tunelyje apskritimu. Superlaidþioje bûsenoje magnetai naudoja labai maþai energijos, nes jeigu toká pat magnetiná laukà bandytume pasiekti áprastu elektromagnetu, tai árenginys paprasèiausiai iðsilydytø. Apie magnetinio lauko stiprumà galima spræsti ið tokio palyginimo: jei ðalia vamzdþio, kuriuo juda protonai, pastatytume sunkveþimá, tai ájungus magnetus, jis bûtø suplotas á blynà.

oh wow... ilgai lauktas eksperimentas pagaliau prasides na, jei zeme prasmegs juodojoj skylej tai kaltinsim tik juos

[sepulture]

XDDD eik sau...negasdink sitp....

[sepulture]

zdziu dbr prikolas tame kd as parodzeu ta straipsni kambriokei o ji juk drba 15min tai ryt perdirbta sita straipsni ides:DDD kazka susies su juodaja skyle ar net pasaulio pabajga. nu ir as tda jau - o neeeeee reike pres gala dr koki vampyriska filma pazet! ji - liko dr viena diena tai reike visus pinigus isleisti!
ir isejo i maxima:DDDDDDDDDDDDDd

[bercana]

fui neprasmegom i skyle ir to gana ....dar daug ka nuveikt spesiu "ka skubaus nuveikt? doro? ne..nedoro...."

[sepulture]

nu kol kas dr jie experimentoja ir mes vs dr gyvos!:DDDDD
taigi, jei kas bus bad, tkr kazkas nudes hawkinga, kaip mes su evillspell spekulevom:DDDDDDDDD

[buvusi_cigarete]

nebus tu juoduju skyliu tikrai patys pagalvokit, juodoji skyle susidaro, kai sprogsta super nova. o cia kalbama apie protonus... man atrodo tikrai nebus o ypac kai zeme tokiu protonu kasdien pasiekia nuo saules, ir dar galingesniu

[sepulture]

ot, taigi taip bvo fajna gasdint XD nemextu realistu tokeis mmntais:DDDD dbr gi laiksrascei kiek dg usdrbo su tokiom spekulecijom:DDDDDD

[ReFaN]

sektantai dar daugiau uzsikale =D

[ReFaN]

nu va, biski teks palaukt didizu atradimu, sustabde sita greitintuva...x] cia delfi video reportazas.

taip jiems ir reikeXD

[Kajitoku]

Manau tokiems parazitams kaip zmonija sunaikinti tokio mazycio aparaciuko neuzteks... Muahahhahaha~~~

beje, jei niekas nezinot dar, papostinsiu naujienas apie si eksperimenta:

LHC Repair Update: Temperature Must Be Raised so Repairmen Don't Die

In case you were still worried about the LHC bringing on the biblical apocalypse, you can calm down, because it turns out the Collider is going to be out of commission for a lot longer than previously thought. The “electrical transformer” problem wasn't the cause of the shutdown at all, and the real problem means the LHC won't be back up and running for at least two months.

CERN spokesman James Gillies explained, “"It's too early to say precisely what happened, but it seems to be a faulty electrical connection between two magnets that stopped superconducting, melted and led to a mechanical failure and let the helium out.” The specific section will have to have its temperature raised significantly above its usual absolute zero so engineers can go in and repair it without dying, which is apparently a very time-consuming process. This kind of failure isn't unusual for particle accelerators, but the LHC's internal temperature makes the whole ordeal much more difficult. Each warm-up or cool-down takes a minimum of several weeks, so the total repair will last more than two months. I suppose we've waited a long time already to unlock the secrets of the universe, so a couple more months can't hurt, right?

LHC Offline Until Spring of 2009

It looks as thought the magnet situation that shut down the LHC last week is going to take even more time to correct than previously feared. In order to fully investigate the problem, researchers have decided to hold off a restart until sometime in the spring of 2009. Robert Aymar, director-general of CERN called the situation "a psychological blow," but getting this beast is in good working order must be the top priority. Apparently, the fire department rushed to the scene after a little over a ton of liquid helium leaked into LHCs super-long tunnel, causing around 100 of the magnets to overheat. Take your time guys—we don't need any more drama with a device that could bring down the world.

taisys puse metu db. o koks ablomas butu , jei isvis nepavyktu tas eksperimentas ;D

[sepulture]

XDDDDDD hahahhaaaaa
hawkingas numirs tda tkr:DDDDDDDDD

[ReFaN]

nu blyn o as tiap tikejaus daug is sit eksperimento..xD
