NEXTorr\u00ae HV 300: performance meet reliability.<\/h1> <\/div>\n<\/div>\n\n\n
\n
\n
\n

In hard and soft X-Ray synchrotron beamlines, where precision and long-term reliability are crucial, maintaining a stable and clean high vacuum is one of the main requirements to avoid detrimental contamination of the optics.
\nAt PolyX beamline –<\/strong>\u00a0National Synchrotron Radiation Centre SOLARIS<\/strong><\/a>, this task was successfully met with a single NEXTorr\u00ae HV 300<\/a><\/strong> pump integrated into the water-cooled double-crystal Si monochromator with multilayer mirrors<\/strong> designed and built by Strumenti Scientifici Cinel<\/strong><\/a>.<\/p>\n <\/div>\n <\/div>\n

\n
\n

For more than<\/strong> 2.5 years<\/strong>, this compact getter\u2013ion hybrid pump kept the operational vacuum stable in the mid E-7 mbar range \u2014 without any bake-out of the monochromator, without neither additional auxiliary pumps nor cryocooling and with no maintenance required<\/strong>.
\nA remarkable demonstration of the reliability and efficiency<\/strong> of SAES High Vacuum\u2019s products.<\/p>\n <\/div>\n <\/div>\n <\/div>\n\n\n\n

Reliable vacuum under challenging conditions<\/h3>

The monochromator environment presents multiple outgassing sources \u2014 optics, actuators, mechanical components, and cabling \u2014 and is routinely operated without any bake-out<\/strong>, thus water vapor and surface contaminants typically compromise vacuum levels.
\nDespite the enhanced gas load, a single NEXTorr HV 300, with a weight of just 3.1 kg and an extremely compact size,<\/strong> maintains high vacuum stability for prolonged time, ensuring constant beamline performance, no contamination of the optics and long-term reliability.<\/p>\n

This result highlights the pump\u2019s exceptional pumping speed for hydrogen and active gases<\/strong>, as well as its sustained sorption capacity, conferred by the ZAO HV getter alloy, <\/strong>allowing for long operational periods even in demanding environments.<\/p>\n

 <\/p>\n

<\/h2>\n

Compact, energy-efficient design that protects optical integrity<\/h2>\n

Operating with only a few watts of power, the NEXTorr HV 300 ensures\u00a0no thermal load irradiated on mirrors or crystals<\/strong>, maintaining full cleanliness of the optics.
\nIts compactness also simplify the installation, making the pump ideal for tight spaces or retrofitting in existing beamline setups<\/strong>.<\/p>\n

By eliminating the need for auxiliary pumps, the system benefits from\u00a0lower vibration, reduced noise, and improved mechanical stability<\/strong>, which are key factors for synchrotron instrumentation<\/a>.<\/p>\n

 <\/p>\n

No maintenance, maximum uptime<\/h2>\n

One of the main advantages for research facilities is\u00a0the absence of maintenance<\/strong>.
\nThe SOLARIS monochromator has run continuously for more than two and a half years without any single intervention \u2014 minimizing operational costs and maximizing\u00a0beam time availability<\/strong>\u00a0for scientists.<\/p>\n

When reactivation is finally needed, the process is fast and user-friendly:\u00a0the NEG element is simply heated for one hour to fully restore its pumping capacity<\/strong>.
\nThis can be easily done by a single operator, with no impact on experimental schedules.<\/p>\n <\/div>\n

Proven results and customer satisfaction<\/h3>

The simplicity of use, reliability, and compactness of the NEXTorr HV 300 translate directly into long-term stability and scientific productivity.
\nFor synchrotron facilities like SOLARIS, it means fewer interruptions, lower costs, and more time dedicated to research.<\/p>\n

 <\/p>\n
