Protective covers from machinery protection specialist Beakbane
will help scientists at Diamond Light Source, the UK's national
synchrotron facility, in their quest to push back the frontiers of
medical knowledge.
The first cover has just been installed on the experimental
table of the newly upgraded I04 beamline, which will go back online
in July; two more covers will follow for use on the similar
beamlines I02 and I03.
One of our most powerful tools in life science research, the
Diamond synchrotron at Harwell accelerates electrons to near light
speed to generate brilliant beams of light ranging in wavelength
from infra-red to X-rays.
The light from the synchrotron is diverted off into a number of
beamlines where it is targeted on experimental samples that are
used for academic and industry research.
Beamline I04 is one of five beamlines dedicated to
macromolecular X-ray crystallography (MX), a technique that can
reveal the detailed structure of complex organic molecules, such as
proteins and DNA structures.
Work on samples including viruses, enzymes and antibodies has
already led to breakthroughs in areas as diverse as preventing
tooth decay, improving antibiotics, finding better anti-cancer
drugs and increasing our understanding of HIV so that treatments
can be developed.
The Beakbane covers enclose the positioning mechanism under the
tables that support the experimental samples, fitting between the
granite base and the moving steel platform. They limit access to
the high quality motion stages used for accurate positioning of the
table providing protection to both people and equipment and give a
clean aesthetic appearance to the experimental area by covering up
essential cables.
As well as being robust and easy on the eye, the covers also
have to meet another important requirement; they have to be able to
stand up to rigorous decontamination procedures after some
experiments.
One MX beamline has been designed to provide laboratory
facilities (biosafety category 3 ) for researchers to work with
bacteria and viruses; one of the safety requirements is the ability
to purge the whole experimental area with hydrogen peroxide vapour,
a strong bleach. The research ultimately provides insight into how
these pathogens cause disease and can lead to new or better
treatments.
Working with the technical staff at Diamond, Beakbane's
development laboratory researched suitable materials, concluding
that some standard materials would not stand up to repeated
exposure to hydrogen peroxide. The solution was a three-sided
folding concertina cover made from a combination of double-sided
PVC coated nylon for the bellows, polyester thread to stitch the
bellows together, and stainless steel end plates. Each cover
measures 1410 by 825mm and extends from 380 to 480mm in height.
Beakbane can draw on its wealth of experience and wide product
range to develop bespoke systems for almost any application. Its
bellows and protective covers are used in applications as diverse
as water treatment, railway locomotives, machine tools,
radiotherapy equipment and nuclear fuel processing facilities.
The type of folding concertina cover used at Diamond is also
used on profiling machines, metrology equipment, lathes, test rigs,
linear drives and other precision mechanisms. It can protect the
equipment from dust, abrasive particles, contaminants and
tampering, while ensuring that the moving parts are safely
enclosed.
Mike Southwell, the Managing Director of Beakbane, commented:
"One of our great strengths is the way we can draw on our wide
range of experience, development facilities and product portfolio
to come up with a system for almost any application. We are
delighted that Diamond came to us to find a solution to their
problem and that we are playing a small part in research that could
improve the lives of millions of people."
