VACUUM

    Vacuum is space that is devoid of matter. The word stems from the Latin adjective vacuus for "vacant" or "void". 

An approximation to such vacuum is a region with a gaseouspressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a perfect vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. The Latin term in vacuo is used to describe an object as being in what would otherwise be a vacuum.

VACUUM FEEDTHROUGHS FOR MEASURING, CONTROLLING AND COUPLING ENERGY

MANY PATHS LEAD TO VACUUM

 

In vacuum technology, completely vacuum-tight seals are vital, coupled to the excellent  insulation offered by ceramics and high level of dielectric strength. LAPP Insulators Alumina offers a wide-ranging programme of standard vacuum feedthroughs to match your needs, whether that be controlling, measuring or directing energy. LAPP Insulators Alumina draws on long years of experience and high levels of know-how in this field. We are your most reliable partner for your special applications and requirements too – guaranteeing our customers quality, reproducibility and satisfaction.

 

Product capabilities

 LAPP Insulators Alumina offers a variety of conductive materials for the manufacture of vacuum feedthroughs such as non-magnetic copper (OFHC) or nickel. Feedthroughs are capable of working at temperatures of between -150°C and +450°C. By using high temperature braze, even higher operating temperatures of over 600°C can be achieved. Surface resistance of the glazed ceramic surface measured against a 5kV DC voltage exceeds 1x1012 ohms. Vacuum feedthroughs from LAPP Insulators Alumina are routinely tested to leak rates of 10-8 mbarL/s. On application we can test to 10-9 mbarL/s. The components’ electrical properties such as maximum voltage and current loading are measured in air; so considerably higher values apply under vacuum. Vacuum technology has been another application for FEM analysis at LAPP Insulators Alumina since 2013. This computer-aided design analysis offers our customers made-to-measure, intelligent solutions. The decisive advantage lies in reduced development times for the absolute optimum design at considerably lower cost, even at the prototype phase. LAPP Insulators Alumina develops components hand-in-glove with customers to series production launch, drawing on the considerable expertise of their in-house research and development department, “LIKE

Innovation

    Alongside standardised component ranges, a division of LAPP Insulators in Germany LAPP Insulators Alumina GmbH produces diverse alternative solutions in ceramic-to-metal, carefully matched to individual customer concepts. To minimise the development period for new ceramic-to-metal components LAPP Insulators Alumina utilises the Finite Element Analysis development tool (FEM for short) to support new product design. Specially for the design of ceramic components, we have a state-of-the-art component break statistical predictive tool. This is capable of rapidly comparing component design variants so that the most robust mechanical design can be chosen before moving to the prototype build stage. Prototype quantities are minimised, resulting in cost savings and project development periods reduced by several weeks. In contrast, simulation testing requires one to two weeks.

 

    LAPP Insulators Alumina develops components in tandem with their customers to series manufacture. We are also pleased to consider commissions from third parties. The costs for a simulation typically lie well below those of tooling for samples. Static and transient thermodynamic calculations are applied, while LAPP Insulators Alumina can draw on the resources of the group research team "LIKE" for magneto-electrical calculations.
