Un grave guasto colpisce il CERN di Ginevra e in particolare il suo acceleratore di particelle LHC, che è fermo da una decina di giorni e richiederà diverse settimane per essere riparato.
All'origine, ha spiegato il fisico Jörg Wenninger venerdì al 12h45 di RTS, c'è la caduta di un albero sulla rete elettrica a Morges. Questo ha perturbato l'approvvigionamento e fatto scattare il sistema di sicurezza. Si è verificato quindi un eccesso di pressione dell'elio, che ha causato una fuga, un piccolo buco di un millimetro quadrato e conseguenze a catena sui magneti.
"Abbiamo spesso piccole panne, ma raramente una grossa come questa", ha affermato Wenninger. Il sistema non sarà rimesso in funzione prima di settembre. Per recuperare il ritardo nella raccolta di dati, attesi da numerosi ricercatori, si ipotizza fra l'altro di accorciare la tradizionale pausa invernale.
L'acceleratore del CERN riprende l'attività
