El passat dia 15 de desembre uns
\nquants alumnes de f\u00edsica i qu\u00edmica de 4t d\u2019ESO, vam assistir a la jornada de portes
\nobertes de l\u2019accelerador de part\u00edcules sincrotr\u00f3 Alba situat al costat del
\ncampus de la Universitat Aut\u00f2noma de Barcelona<\/span><\/span><\/a><\/span>, a <\/span>Cerdanyola del Vall\u00e8s<\/span><\/span><\/a><\/p>\n

<\/span>L’Alba consta d’un <\/span>accelerador de part\u00edcules lineal<\/span><\/span><\/a><\/span> i un sincrotr\u00f3 En ells s’acceleren els <\/span>electrons<\/span><\/span><\/a><\/span> fins a velocitats properes a la de la <\/span>llum<\/span><\/span><\/a><\/span>, arribant a una energia de fins a 3 Giga <\/span>electronvolts<\/span><\/span><\/a><\/span> (GeV). Aquests electrons s’injecten en un anell d’emmagatzematge de 270 metres de per\u00edmetre que est\u00e0 equipat per produir <\/span>radiaci\u00f3 electromagn\u00e8tica<\/span><\/span><\/a><\/span> d’una gama cont\u00ednua de <\/span>longituds d’ona<\/span><\/span><\/a><\/span>, des de la llum visible fins als <\/span>raigs X<\/span><\/span><\/a><\/span>. \u00c9s una font de tercera generaci\u00f3, en qu\u00e8 la major part de la llum procedeix de dispositius d’inserci\u00f3.<\/span>
<\/span>Un sincrotr\u00f3 \u00e9s un tipus particular d’<\/span>accelerador de part\u00edcules<\/span><\/span><\/a><\/span> circular en qu\u00e8 el <\/span>camp magn\u00e8tic<\/span><\/span><\/a><\/span> (que fa que les part\u00edcules girin) i el <\/span>camp el\u00e8ctric<\/span><\/span><\/a><\/span> (que accelera les part\u00edcules) estan sincronitzats de forma precisa amb el feix de part\u00edcules en moviment. <\/span><\/font><\/p>\n

<\/span>Aquests aparells tenen un gran nombre d’aplicacions en \u00e0mbits molt diversos com medecina, f\u00edsica, paleontologia, cosm\u00e8tica…<\/p>\n

<\/span>Ens va agradar molt, i ens va semblar una experi\u00e8ncia molt interessant.<\/span><\/font><\/p>\n<\/p>\n
