Leybold designs new TURBOVAC iR model collection for R&D

With the TURBOVAC iR variants, vacuum producer Leybold is launching a new, complete turbomolecular pump collection, technologically derived from the proven TURBOVAC i household. “The iR fashions exchange the former TURBOVAC ClassicLine pumps and meet, for example, the requirements of our high-end research customers – such as the most important analysis institutes CERN or DESY,” summarizes the accountable product supervisor, Petr Lastovicka.
Accordingly, the TURBOVAC iR was designed for versatile remote operation from three meters to distances of 1 kilometre. In all aspects the merchandise have been additionally designed to withstand the challenges which are present in environments with high to very high ionizing radiation. “For this, we offer special cable lengths of as much as 200 meters, and likewise the option for the customers to make use of their own cables,” explains product supervisor Petr Lastovicka. According to digital pressure gauge , the iR fashions have been developed using the present materials information of the research community: As a end result, the supplies they contain have radiation tolerances of as a lot as 1 million grays (Gy).
In mixture with the ion getter and non-evaporable getter pumps, so referred to as ultra-high vacuum pumps, “These attributes set them apart from standard market models, that are meeting the market requirements but not particularly those needed for the particular circumstances encountered in analysis centers,” says Petr Lastovicka. This is totally different with the TURBOVAC iR product sequence: on the one hand, they were developed for the special necessities relating to cable size and radiation tolerance. “In addition, we will supply the TURBOVAC iR pumps combined with our ion pumps and NEG pumps, which other suppliers can’t provide as a package deal,” provides Lastovicka. TURBOVAC iR matches perfectly nicely in the TURBOVAC i eco systems as other products such as accessories or the software program LeyAssist may be utilized as nicely.
The backside line is that the brand new iR fashions are designed to meet the technical necessities of the high-energy physics market. This makes them predestined for functions 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

where they are not uncovered to radiation,” explains Petr Lastovicka.
Another elementary condition in these utility areas is absolutely the purity of the pump: this core requirement is fulfilled by the oil-free operation of the bearing system of the brand new TURBOVAC iR collection. The TURBOVAC iR additionally helps 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 advantage: The built-in, new TURBO.DRIVE controller automatically acknowledges the pump model and instantly adjusts to the particular working 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 accessories range of supporting controllers and cable options to fulfill buyer wants for

additional cable lengths and intelligent options. The clever Controller TURBO.DRIVE 500eC has been launched in April and the TURBOVAC iR sizes 1350 and 1450 will comply with within the third quarter of 2022 together with the more powerful controller possibility to realize even longer cable lengths.
