Pfaff-silberblau supplies PHOENIX telescopic lifting column for electron storage ring BESSY II

By | Nov 07, 2018

PHOENIX telescopic lifting columns from Columbus McKinnon Engineered Products can be used in a variety of applications, as illustrated by the current example of a special test bench application at the Helmholtz-Zentrum Berlin. Here, the Pfaff-silberblau lifting column PHOENIX takes over the manual height adjustment when guiding a photon beam to experimental stations (beamlines) – as sensitively as possible and backlash-free in order to guide the photon beam precisely through narrow apertures. The telescopic lifting column should therefore be as stiff as possible and the telescopic guide free of side play. Due to its technical design, Pfaff-silberblau's PHOENIX telescopic lifting column was able to meet the high demands of scientists in the standard version so well that no additional design effort was required for the height adjustment.

Exact height adjustment at the beamlines

At the Helmholtz-Zentrum Berlin für Materialien und Energie (HZB), scientists conduct research into complex material systems. They operate and use the photon source BESSY II – a synchrotron that delivers brilliant photon pulses. Experimental stations are connected to 48 beam holes. At one of these beamlines, researchers from the Max Planck Society investigate electrochemical processes in complex material systems under realistic conditions.

The experiments take place in a vacuum of 10-5 mbar. In the connected electron storage ring, on the other hand, there is an ultrahigh vacuum of 10-9 mbar. This is why a pumping stage with several chambers connected in series, which continuously sucks off gas with turbomolecular pumps, is necessary between the beam exit from a mirror chamber and the actual experiment. The individual chambers are connected to one another in such a way that the photon beam with a diameter of approximately 2 mm has to be precisely guided through apertures with diameters of 3 mm.

For this application, a lifting column was needed with a height of about 1200 mm, which can reliably support a weight force of at least 700 N and as such the pumping stage with the pumps and allow precision adjustment. It has to be adjustable in height by 500 mm in order to use it at other experimental stations with different beam heights.

The PHOENIX telescopic lifting column with manual drive and a lifting capacity of 1500 N has proven itself to be an ideal solution for this. The base plate of the telescopic lifting column is bolted directly to the floor of the experimental hall. The upper head plate of the PHOENIX lifting column has been removed and replaced with an adjustment unit that allows pivoting and alignment of the attached pumping stage in four degrees of freedom with an accuracy of up to 0.05 mm. The closed outer housing made of robust aluminium profile tubes makes the PHOENIX lifting columns from Pfaff-silberblau insensitive to dirt and thus also low maintenance.

The solution was set up within a week and aligned with a theodolite exactly to the photon beam. The pumping stage has been operating trouble-freely for about six months, without any readjustment being necessary to date.

Multi-lifting systems also possible

PHOENIX telescopic lifting columns from Pfaff-silberblau can also be combined into multi-lifting systems. The precision of the lifting process, the admissible off-centre load pick-up and its versatility in the way it is installed – vertically, horizontally or headfirst – qualify these lifting columns for a wide range of tasks. As such, they are also used in height-adjustable work stations, e.g. in engine assembly in automotive production, for the positioning of components in stop-and-go mode of production lines and for lifting large and heavy components with variable geometry, e.g. in wing assembly in aircraft construction.
