Another project LPI received Skolkovo resident status

Work on the creation of magnetic resonance imaging with superconducting magnets at the Physics Institute. PN Lebedev (FIAN), has reached a new level. Development of a unique aneroid (without liquid helium) imager group of scientists will conduct as members of the Skolkovo project.

     The problem aneroid cooling a superconducting magnet is today one of the major challenges in the field of magnetic imaging. The fact is that in the normal CT scanner requires filling with liquid helium — an expensive material, the use of which also complicates the maintenance of the device. Scientists from the Lebedev Institute have developed orthopedic tomography (that is used to study the state of the limbs) with minimized helium content — it lasts for a few years — and even got a few commercial orders for it from scientific organizations. The next step is the creation of physics called the scanner, which will work without helium. Instead of expensive liquid cooling it uses a special type. The layout of the coolant in the LPI has been created.

     On the mechanism of aneroid cooling the magnet says the project manager, head of department of cryogenic Lebedev Physical Institute, Doctor of Physical and Mathematical Sciences Eugene Demikhov: "We have developed a series of laboratory superconducting magnets that operate in the cooling mode, aneroid, which is our achievement. Recently, the technique of low temperatures spread cryogenic refrigerators. In some approximate sense, they are a modification of the usual over the refrigerator. Conventional refrigerator can freeze using Freon up to -80 ° C, if, instead of Freon for such a system to take the helium gas, the refrigerator can cool up to a temperature of 4 K. We use the fridge and connect our magnetic coil from a superconductor to it. If certain way to design the system and fit properly position its elements, it is possible to do entirely without liquid helium. "

     Aneroid cooling system development and other work in this important sphere engaged a team of specialists, who will continue to operate under the auspices of "MR Tomografiks" created at the beginning of the project. It consists mainly of young scientists and graduate students. President of The graduate MIPT Maria Petrova. Now the formation of the team continues and the company is interested in new employees. Basic requirements for candidates to participate in the project — an interest in application development and possession of basic knowledge about magnetic fields and superconductivity.

     In the implementation of the planned company will help the Skolkovo resident status, she received recently. The company meets the essential requirements of the participants ambitious project: it offers an innovative product and formed directly from the development team (under the terms of Skolkovo resident company may be engaged in research and development, rather than the production and sale). Eugene Demikhov: "Residency at Skolkovo provides great advantages for the development of the business. It is a question about bonuses and to support young workers, for example, in terms of housing."

     In addition, this year the Ministry of Industry and Trade has supported another project proposed in cryogenic Department of FIAN. For three years, scientists based orthopedic tomography (pictured right) are planning to create a device for the visualization and diagnosis of the condition of the body. The Imager will be manufactured in accordance with the parameters familiar to physicians. The magnetic field strength of 1.5 T, the diameter of the workspace — 60 cm last feature new scanner differs from its orthopedic "colleague", which diameter of the hole is 20 cm (scheduled to increase to 24-26 cm). This raises some specific requirements for the job. Eugene Demikhov: "This is a device of another scale. Compared with the previous imager sizes up to about 3 times. Coil weight with a cryostat — about 3 tons, coil diameter — about 2 meters. This means that the problem is more complicated. Accordingly, we need a more complex calculations distribution the magnetic field strength is required other software — all you need to do in a new way. "

     It is assumed that in addition to a magnetic resonance imaging will be created and scattered components of the unit. Among them — the magnetic system alone (coil), a complex digital electronics, the registration system (detection coil) and gradient-correction module. Each of the items can be sold separately, so special care will be taken to the task of developers creating universal components.
