With the TURBOVAC iR variants, vacuum manufacturer Leybold is launching a model new, complete turbomolecular pump sequence, technologically derived from the confirmed TURBOVAC i family. “The iR models exchange the former TURBOVAC ClassicLine pumps and meet, for example, the necessities of our high-end research clients – corresponding to the major research institutes CERN or DESY,” summarizes the responsible product manager, Petr Lastovicka.
Accordingly, the TURBOVAC iR was designed for versatile distant operation from three meters to distances of 1 kilometre. In all aspects the merchandise have been also designed to withstand the challenges which are present in environments with high to very excessive ionizing radiation. “For this, we provide special cable lengths of up to 200 meters, and in addition the option for the users to make use of their very own cables,” explains product manager Petr Lastovicka. According to Lastovicka, the iR fashions had been developed utilizing the existing materials knowledge of the analysis group: As a result, the supplies they comprise have radiation tolerances of up to 1 million grays (Gy).
In combination with the ion getter and non-evaporable getter pumps, so known as ultra-high vacuum pumps, “These attributes set them apart from normal market fashions, which are assembly the market necessities but not particularly these needed for the particular circumstances encountered in analysis facilities,” says Petr Lastovicka. This is totally different with the TURBOVAC iR product sequence: on the one hand, they had been developed for the special requirements relating to cable length and radiation tolerance. “In digital pressure gauge , we are in a position to provide the TURBOVAC iR pumps mixed with our ion pumps and NEG pumps, which different suppliers can’t supply as a package,” adds Lastovicka. TURBOVAC iR matches perfectly nicely in the TURBOVAC i eco methods as different products corresponding to equipment or the software program LeyAssist may be utilized as nicely.
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 such as 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

where they don’t seem to be 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 model new TURBOVAC iR sequence. The TURBOVAC iR also 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 mechanically acknowledges the pump mannequin and immediately adjusts to the particular working modes.
The TURBOVAC iR range utterly covers all existing members of the TURBOVAC i household with pumping speeds from ninety to 950 l/s. In parallel, Leybold will successively broaden the accessories range of supporting controllers and cable options to meet customer needs for

additional 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 follow within the third quarter of 2022 along with the extra powerful controller possibility to realize even longer cable lengths.
