With the TURBOVAC iR variants, vacuum producer Leybold is launching a new, complete turbomolecular pump series, technologically derived from the confirmed TURBOVAC i family. “The iR fashions substitute the previous TURBOVAC ClassicLine pumps and meet, for instance, the necessities of our high-end analysis clients – corresponding to the main research institutes CERN or DESY,” summarizes the responsible product supervisor, Petr Lastovicka.
Accordingly, the TURBOVAC iR was designed for flexible distant operation from 3 meters to distances of one kilometre. In all elements the merchandise have been additionally designed to withstand the challenges that are current in environments with high to very excessive ionizing radiation. “For this, we provide special cable lengths of as a lot as 200 meters, and in addition the choice for the users to use their own cables,” explains product manager Petr Lastovicka. According to Lastovicka, the iR models had been developed utilizing the prevailing material knowledge of the research community: As a result, the supplies they contain have radiation tolerances of as much as 1 million grays (Gy).
In mixture with the ion getter and non-evaporable getter pumps, so called ultra-high vacuum pumps, “These attributes set them other than standard market models, that are meeting the market necessities but not specifically those wanted for the particular circumstances encountered in analysis centers,” says Petr Lastovicka. This is completely different with the TURBOVAC iR product sequence: on the one hand, they have been developed for the special requirements concerning cable size and radiation tolerance. “In addition, we can provide the TURBOVAC iR pumps mixed with our ion pumps and NEG pumps, which other suppliers can’t offer as a bundle,” provides Lastovicka. TURBOVAC iR fits perfectly properly within the TURBOVAC i eco techniques as other products similar to accessories or the software program LeyAssist could be utilized as well.
The backside 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 purposes similar to synchrotrons (particle accelerators), cyclotrons (circular accelerators), linear accelerators and free-electron lasers. “In these areas, customers can remove the electronics and place them in areas

the place they don’t seem to be uncovered to radiation,” explains Petr Lastovicka.
Another elementary situation in these software areas is the absolute purity of the pump: this core requirement is fulfilled by the oil-free operation of the bearing system of the model new TURBOVAC iR series. The TURBOVAC iR additionally supports all related communication options of the TURBOVAC I, USB, 15-pin digital I/O and all serial and fieldbus choices of the TURBO.DRIVE 500e. pressure gauge octa : The built-in, new TURBO.DRIVE controller automatically acknowledges the pump mannequin and instantly adjusts to the specific operating modes.
The TURBOVAC iR vary completely covers all current members of the TURBOVAC i family with pumping speeds from ninety to 950 l/s. In parallel, Leybold will successively increase the accessories vary of supporting controllers and cable choices to fulfill customer needs for

extra cable lengths and intelligent solutions. The clever Controller TURBO.DRIVE 500eC has been launched in April and the TURBOVAC iR sizes 1350 and 1450 will comply with in the third quarter of 2022 together with the extra highly effective controller possibility to understand even longer cable lengths.
