The ICT Research Center of Nano Science and Technology Department of NICT Nano Science and Technology developed the ion pump whose volume and weight are only about 1/10 of traditional products. Ion pump size of diameter 100mm × 200mm long, weighs 1.3kg. It is envisioned to be used in electron microscopes as well as small vacuum equipment that can handle high vacuum environments of 10-8 to 10-9 Torr (10-6 to 10-7 Pa). In addition to the ion pump, NICT has also developed vacuum equipment that can carry a 10mm side sample in a 20mm side sample container. Vacuum equipment consists of ion pumps, power supplies, sample vessels, and gate valves connected to a large vacuum chamber. Ion pump is placed in the luggage filled with cushioning material, the total weight of about 6kg. This small ion pump was presented at "nano tech 2007 International Conference on Nanotechnology Synthesis Technology". NICT said it will strive for the sale of ion pumps and vacuum equipment for this development. The use of 4 5 batteries work In order to meet the needs of carrying, the vacuum pump while reducing the size of the power consumption. The use of 4 5 batteries can work continuously for 20 hours. In the past, the ion pump was usually driven by a lead-acid battery for automobiles during transportation. Due to the total weight is too heavy, can only be transported by trailer. Therefore, it is necessary to use a device such as a damper capable of absorbing impact, which is very difficult to handle. The ion pump uses materials lighter than the stainless steel vacuum pump commonly used, and improved electrode structure, thus successfully achieving the miniaturization and energy saving. A typical ion pump employs a structure in which two negative electrodes sandwich a cylindrical positive electrode. The current ion pump "by the electrode structure from the previous two-dimensional to three-dimensional, so that miniaturization and low voltage, low current drive has become possible"
