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 series, technologically derived from the confirmed TURBOVAC i family. “The iR models exchange the former TURBOVAC ClassicLine pumps and meet, for instance, the requirements of our high-end analysis clients – such as the most important research institutes CERN or DESY,” summarizes the accountable product supervisor, Petr Lastovicka.
Accordingly, the TURBOVAC iR was designed for versatile distant operation from three meters to distances of one kilometre. In all aspects the products had been additionally designed to withstand the challenges which are current in environments with high to very excessive ionizing radiation. “For this, we provide particular cable lengths of as much as 200 meters, and in addition the option for the customers to make use of their own cables,” explains product supervisor Petr Lastovicka. According to Lastovicka, the iR fashions had been developed utilizing the existing materials information of the research group: As a outcome, the materials they contain have radiation tolerances of up to 1 million grays (Gy).
In combination with the ion getter and non-evaporable getter pumps, so referred to as ultra-high vacuum pumps, “These attributes set them aside from commonplace market fashions, which are assembly the market requirements however not particularly those needed for the particular conditions encountered in analysis facilities,” says Petr Lastovicka. This is completely different with the TURBOVAC iR product collection: on the one hand, they had been developed for the particular requirements relating to cable size and radiation tolerance. “In addition, we are in a position to provide the TURBOVAC iR pumps mixed with our ion pumps and NEG pumps, which other suppliers can’t supply as a package,” adds Lastovicka. TURBOVAC iR matches diaphragm seal in the TURBOVAC i eco techniques as different merchandise such as accessories or the software LeyAssist can 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 corresponding 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

where they are not uncovered to radiation,” explains Petr Lastovicka.
Another elementary situation in these application 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 collection. The TURBOVAC iR additionally helps all related communication choices of the TURBOVAC I, USB, 15-pin digital I/O and all serial and fieldbus choices of the TURBO.DRIVE 500e. Another advantage: The built-in, new TURBO.DRIVE controller routinely acknowledges the pump model and instantly adjusts to the particular operating modes.
The TURBOVAC iR range utterly covers all existing members of the TURBOVAC i household with pumping speeds from 90 to 950 l/s. In parallel, Leybold will successively broaden the equipment vary of supporting controllers and cable options to fulfill buyer needs for

additional cable lengths and intelligent solutions. The clever Controller TURBO.DRIVE 500eC has been released in April and the TURBOVAC iR sizes 1350 and 1450 will follow within the third quarter of 2022 along with the more highly effective controller possibility to understand even longer cable lengths.
