Le applicazioni finali contemplano <\/span>la ricerca di base, studi sui semiconduttori, ricerca su materiali esotici, sviluppo di celle a combustibile, e altro ancora. Per ottenere misur<\/span>e<\/span> di alta qualit\u00e0, i<\/span> sistemi di<\/span> Surface Science richied<\/span>ono<\/span> pompe che forniscono un’<\/span>elevata <\/span>velocit\u00e0 di pompaggio per l’H2, <\/span>gas principal<\/span>e<\/span> in <\/span>ultra alto<\/span> vuoto<\/span>, nonch\u00e9 l’assenza di vibrazioni, campi magnetici ridotti o assenti (statici o gradienti di B) e <\/span>un grado di pulizia elevato, in modo da<\/span> ridurre al minimo interferenze <\/span>con le m<\/span>isur<\/span>e<\/span>. Le pompe <\/span>CapaciTorr<\/span> Z, accoppiate <\/span>a<\/span> soluzioni di pompaggio normalmente presenti in tali sistemi \u2013 come pompe turbo molecolari, pompe ioniche, pompe criogeniche \u2013 <\/span>sono una scelta <\/span>efficace<\/span> per raggiungere rapidamente il vuoto richiesto, diminuire i tempi di pump down e mantenere condizioni da UHV a lungo.<\/span> Inoltre, <\/span>le pompe <\/span>NEXTorr<\/span> Z<\/span>, come i modelli su flangia CF63 e CF100 (N<\/span>EXTorr<\/span> Z500, <\/span>NEXTorr <\/span>Z1000 <\/span>e NEXTorr<\/span> Z2000<\/span>)<\/span>, <\/span>permettono l\u2019ottimizzazione del sistema in termini di spazio e <\/span>maneggevolezza<\/span> in quanto, implementando una pompa ionica in sinergia con l\u2019elemento getter, possono rimpiazzare pompe prees<\/span>istenti, pi\u00f9 voluminose e pesanti<\/span>.\u00a0<\/span><\/span>\u00a0<\/span><\/p>\n <\/div>\n <\/div>\n <\/div>\n\n\n

Alta Velocit\u00e0 di Pompaggio <\/h3>

L’alta velocit\u00e0 di pompaggio per l’H2 \u00e8 essenziale per ottenere condizioni UHV profonde e pulite, garantendo che il sistema sia esente da contaminanti e impurit\u00e0 indesiderati che potrebbero interferire con le misurazioni.<\/p>\n <\/div>\n <\/div>\n <\/div>\n

Senza Vibrazioni <\/h3>

L’assenza di vibrazioni \u00e8 un aspetto chiave per evitare qualsiasi disturbo che possa influenzare la precisione e l’accuratezza delle misurazioni. <\/p>\n <\/div>\n <\/div>\n <\/div>\n

Campo Magnetico Minimo <\/h3>

Campi magnetici ridotti o assenti (statici o gradienti di B) sono spesso necessari per minimizzare interferenze non volute sulle misure, consentendo la raccolta di dati accurati e ripetibili. <\/p>\n <\/div>\n <\/div>\n <\/div>\n

Ambiente Pulito <\/h3>

Essendo sistemi da UHV, \u00e8 importante mantenere un ambiente da vuoto pulito per evitare qualsiasi contaminazione che potrebbe interferire con le misurazioni. Le pompe NEG di SAES si basano su dischi getter sinterizzati, che forniscono una soluzione di pompaggio priva di particelle, garantendo una estrema pulizia del sistema da vuoto<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n<\/div>\n\n\n
