Le pompe SAES svolgono un ruolo cruciale per ottenere misurazioni di alta qualit\u00e0<\/h2>
Vantaggi<\/div> <\/div>\n <\/div>\n

I sistemi di Surface Science giocano un ruolo fondamentale nello studio dei fenomeni e delle propriet\u00e0 fisiche e chimiche dei materiali all\u2019interfaccia di diverse fasi, come solido-liquido, solido-gas e solido-vuoto. Tali sistemi richiedono condizioni di lavoro ultra-pulite e pressioni base molto basse a seconda della tecnica utilizzata: ARPES, SPM, XPS, LEEM\/PEEM, MBE, per menzionarne alcune. Le pressioni base sono tipicamente nel range 1E-9 \u2013 1E-11 Torr. Le applicazioni finali contemplano la ricerca di base, studi sui semiconduttori, ricerca su materiali esotici, sviluppo di celle a combustibile, e altro ancora. Per ottenere misure di alta qualit\u00e0, i sistemi di Surface Science richiedono pompe che forniscono un\u2019elevata velocit\u00e0 di pompaggio per l\u2019H2, gas principale in ultra alto vuoto, nonch\u00e9 l\u2019assenza di vibrazioni, campi magnetici ridotti o assenti (statici o gradienti di B) e un grado di pulizia elevato, in modo da ridurre al minimo interferenze con le misure. Le pompe CapaciTorr Z, accoppiate a soluzioni di pompaggio normalmente presenti in tali sistemi \u2013 come pompe turbo molecolari, pompe ioniche, pompe criogeniche \u2013 sono una scelta efficace per raggiungere rapidamente il vuoto richiesto, diminuire i tempi di pump down e mantenere condizioni da UHV a lungo. Inoltre, le pompe NEXTorr Z, come i modelli su flangia CF63 e CF100 (NEXTorr Z500, NEXTorr Z1000 e NEXTorr Z2000), permettono l\u2019ottimizzazione del sistema in termini di spazio e maneggevolezza in quanto, implementando una pompa ionica in sinergia con l\u2019elemento getter, possono rimpiazzare pompe preesistenti, pi\u00f9 voluminose e pesanti.<\/p>\n <\/div>\n <\/div>\n <\/div>\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

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
