Leybold designs new TURBOVAC iR model series for R&D

With the TURBOVAC iR variants, vacuum producer Leybold is launching a new, full turbomolecular pump series, technologically derived from the confirmed TURBOVAC i family. “The iR models replace the former TURBOVAC ClassicLine pumps and meet, for example, the necessities of our high-end analysis customers – such as the major 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 1 kilometre. In all aspects the products had been additionally designed to withstand the challenges that are present in environments with high to very high ionizing radiation. “For this, we provide special cable lengths of up to 200 meters, and also the option for the customers to use their very own cables,” explains product manager Petr Lastovicka. According to Lastovicka, the iR fashions have been developed utilizing the prevailing material data of the analysis community: As a result, the materials they contain have radiation tolerances of as a lot as 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 other than commonplace market models, which are meeting the market necessities however not specifically these needed for the particular situations encountered in analysis centers,” says Petr Lastovicka. This is completely different with the TURBOVAC iR product series: on the one hand, they had been developed for the special requirements relating to cable size and radiation tolerance. “In addition, we are ready to provide the TURBOVAC iR pumps mixed with our ion pumps and NEG pumps, which other suppliers can not supply as a bundle,” adds Lastovicka. TURBOVAC iR suits completely nicely in the TURBOVAC i eco systems as other products similar to accessories or the software program LeyAssist may be utilized as well.
The bottom line is that the new iR models are designed to fulfill the technical requirements 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 take away the electronics and place them in areas
the place they are not exposed to radiation,” explains Petr Lastovicka.
Another elementary condition 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 brand new TURBOVAC iR series. The TURBOVAC iR also supports all related communication options of the TURBOVAC I, USB, 15-pin digital I/O and all serial and fieldbus options of the TURBO.DRIVE 500e. Another benefit: The built-in, new TURBO.DRIVE controller routinely acknowledges the pump model and immediately adjusts to the specific operating modes.
The TURBOVAC iR range completely covers all existing members of the TURBOVAC i family with pumping speeds from 90 to 950 l/s. In parallel, Leybold will successively increase the equipment vary of supporting controllers and cable choices to fulfill customer wants for
additional cable lengths and clever solutions. xp2i .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 realize even longer cable lengths.
