WATMASS is a product where the ion source has been improved to allow high precision residual gas analysis in the lower 10-7 Pa (10-9 mbar) range.
When residual gas analysis is performed in ultra-high vacuum/extreme-high vacuum (UHV/XHV) at 10-7 Pa (10-9 mbar) or lower using a typical quadrupole residual gas analyser, the out gas from the ion sources at the sensor tips can no longer be ignored, and it becomes extremely difficult to perform high-precision gas analysis.
The Magic NEG pump is a new getter pump architecture designed to enhance pumping capacity in the extreme-high vacuum (XHV) range. The pump’s materials and structural design have been optimized to significantly reduce hydrogen outgassing from the pump itself. By combining the Magic NEG pump with either a turbomolecular pump (for open systems) or a small ion pump (for sealed systems) as an auxiliary pump, it is possible to achieve XHV levels on the order of 10-10 Pa (10-12 mbar) within 24 hours of starting from atmospheric pressure.
The Atomised Granule Non-Evaporable Getter (AG-NEG) pump is an innovative non-evaporable getter (NEG) pump that utilises NEG powder produced through advanced non-contact atomisation technology. The powder grains are used in their original form without compression consolidation. Due to the virtually spherical shape of the NEG particles and their highly stable surface condition, the pump exhibits high pumping speed and exceptionally reliable pumping characteristics.
The smooth, stable particle surfaces result in minimal self-gas emissions from the surface layer during repeated pumping cycles, making the AG-NEG pump ideal for achieving ultra-high vacuum (UHV) and extreme-high vacuum (XHV) conditions. Additionally, the use of relatively large grains with particle diameters around 100 µm allows the NEG particles to be thinly packed into a disc-shaped, heat-conductive container fitted with a 30 µm fine metal mesh, effectively preventing any risk of particle dispersion.
Furthermore, since the NEG particles are activated through conduction heating from a centrally positioned heater pipe (air side), radiant heat during activation is significantly minimized.
The “magic nipple” is a unique product developed by our company that utilises the properties of 0.2% BeCu alloy materials.
Hot cathode ionization gauges such as the BA gauge are often large gas sources in extreme-high vacuum environments. If you touch near the gauge port when the gauge is on, it should be quite hot. Inside is much hotter. Everyone has probably thought at one time “I want to disconnect the hot cathode ionization gauge to get a lower vacuum” . However , without the vacuum gauge it is not possible to know the vacuum inside. There is no real option, and most people probably give up.
In this kind of situation, you should try the “magic nipple”. If you insert the BAG or EXG that you are using into the “magic nipple” and then attach it to a stainless steel gauge port, then the gas emissions from the vacuum gauge will decrease as if by magic despite having done nothing to the vacuum gauge itself. The trick is the large difference (complete reversal) of emissivity and thermal conductivity of the 0.2% BeCu alloy from our company compared to stainless steel (also applies to titanium).

3BG is a commercially extreme-high vacuum hot-cathode ionization gauge head that can measure pressure as low as 5.4 X 10-12Pa (5.4 x 10-14 mbar), by reducing the limit imposed by soft x-rays, electron- stimulated desorption (ESD), and outgassing.
The gauge construction includes a cylindrical grid, which is close at both ends; ions are drawn from the grid through a long, axial slit made in the cylindrical surface.Thus, the ion beam that emerges forms a “belt”.This belt-like ion beam is guided on a terminates on a plate collector arranged after a beam trajectory rotation of 240°. These elements are embedded in a solid cylinder of 0.2% BeCu alloy, which has a low emissivity (radiation factor) and high thermal conductivity. As a result, the effects of heat radiation and outgassing (caused by the hot-cathode filament) and soft x- ray photoemission(the grid is the soft x-ray source) are reduced in the deflector/collector region. This electrode arrangement can also greatly decrease the flux of soft x-rays and ESD in the direction of the belt ion beam because it sets to 90°the angle between the extracted gas-phase ion beam and the maximum flux of soft x-rays and ESD.
In addition, it achieves an extremely low pressure measurement limit by minimizing loss in the ion transport, and because the collector is well hidden, being located after the large deflection of the ion beam.
