Leybold designs new TURBOVAC iR model sequence for R&D

With the TURBOVAC iR variants, vacuum manufacturer Leybold is launching a model new, full turbomolecular pump sequence, technologically derived from the proven TURBOVAC i family. “The iR fashions replace the former TURBOVAC ClassicLine pumps and meet, for instance, the necessities of our high-end analysis clients – similar to the most important analysis institutes CERN or DESY,” summarizes the responsible product manager, Petr Lastovicka.
Accordingly, the TURBOVAC iR was designed for versatile distant operation from 3 meters to distances of 1 kilometre. In all features the merchandise have been also designed to withstand the challenges which are current in environments with high to very excessive ionizing radiation. “For this, we offer particular cable lengths of up to 200 meters, and likewise the option for the customers to make use of their own cables,” explains product manager Petr Lastovicka. According to เกจวัดแรงดัน , the iR models had been developed utilizing the existing materials knowledge of the research group: As a outcome, the supplies they comprise have radiation tolerances of up to 1 million grays (Gy).
In mixture with the ion getter and non-evaporable getter pumps, so known as ultra-high vacuum pumps, “These attributes set them apart from standard market models, which are assembly the market requirements however not particularly those needed for the actual circumstances encountered in research facilities,” says Petr Lastovicka. เพรสเชอร์เกจ is completely different with the TURBOVAC iR product series: on the one hand, they had been developed for the particular necessities concerning cable size and radiation tolerance. “In addition, we can supply the TURBOVAC iR pumps combined with our ion pumps and NEG pumps, which different suppliers can not supply as a package,” adds Lastovicka. TURBOVAC iR fits perfectly properly within the TURBOVAC i eco methods as different merchandise similar to equipment or the software program LeyAssist may be utilized as well.
The bottom line is that the new iR models are designed to meet the technical necessities of the high-energy physics market. This makes them predestined for applications similar to synchrotrons (particle accelerators), cyclotrons (circular accelerators), linear accelerators and free-electron lasers. “In these areas, users can remove the electronics and place them in areas

the place they aren’t exposed to radiation,” explains Petr Lastovicka.
Another elementary situation in these application areas is absolutely the purity of the pump: this core requirement is fulfilled by the oil-free operation of the bearing system of the model new TURBOVAC iR collection. The TURBOVAC iR additionally supports all relevant communication choices of the TURBOVAC I, USB, 15-pin digital I/O and all serial and fieldbus options of the TURBO.DRIVE 500e. Another advantage: The built-in, new TURBO.DRIVE controller automatically acknowledges the pump model and instantly adjusts to the precise working modes.
The TURBOVAC iR vary completely covers all current members of the TURBOVAC i household with pumping speeds from ninety to 950 l/s. In parallel, Leybold will successively increase the accessories range of supporting controllers and cable options to meet customer needs for

additional cable lengths and clever solutions. The intelligent Controller TURBO.DRIVE 500eC has been released in April and the TURBOVAC iR sizes 1350 and 1450 will follow in the third quarter of 2022 together with the more highly effective controller option to realize even longer cable lengths.
Applications at a look:
Particle Accelerator

– Synchrotron Beamline / End station

– Synchrotron Ring

Research

– LINAC (Linear Accelerator) electron in research

– Particle accelerator cyclotron beamline/experiment

– Particle accelerator cyclotron system

– Laser – free-electron laser (FEL)

– Classic Fusion & Laser Fusion

Medical:
– Particle accelerator cyclotron system

– LINAC (Linear Accelerator) heavy ions

– Sterilization

Industrial/Semi

General requirement to have remote

operation of the TMP

Key Success Factors:
– Strong tolerance for radiation environments

– Flexible remote operation over very lengthy distances

– Excellent performance for gentle gases

– No oil/particle emission from the pump

– Partly tolerance for magnetic fields

– Easy upkeep (onsite)
