About Us
EGKENN Vacuum Technology sp. z o. o. originated from UK based company NTE Vacuum Technology that doesn’t exist any more but our EGKENN set by the old NTE’s
ex-employee Tomasz Rak carries out it’s heritage and wealth of experience gained over the 13 years of their continuous employment supported
by the retired owner of NTE - Eric Kennedy ...
Back at NTE we have developed a set of skills which have embedded it as a supplier to some of the world's most advanced technology organisations, including CERN, Culham, Rutherford Appleton, and the UK Astronomy Technology Centre. Our core strength lies in its ability to provide the housings, vessels and fabricated structures for the projects such as ALMA, LIGO, KMOS or SCUBA 2 -a highly specialised camera for the use in 'submillimeter' astronomy. General requirements include high accuracy, suitability for low temperature and /or high vacuum environments; NTE's success was based on expertise in welding and design techniques, and use of highly rigid machine tool technology. You might imagine stainless steel to be the preferred material for vacuum chambers. However, for certain applications aluminium has some important advantages. For example it is a third of the weight which is important when the chambers are attached to the giant telescopes in Hawaii and Chile; and in nuclear physics applications the chambers are often subjected to high radiation – so aluminium's half life of 24 hours is extremely attractive compared to 22,000 years for stainless steel. One of our specialities is making large, medium and small aluminium vacuum chambers/vessels. In this field NTE used to be and EGKENN probably is the only serious contender in the UK, and one of a handful in Europe. Welding of aluminium to high vacuum standards is far harder than for stainless steel and demands completely different techniques: The first aluminium chamber of any size was made back in the 1980s, when NTE won the contract, against European competition, for 24 vacuum chambers for the Aleph detector at CERN. The ex-managing director of NTE - Eric Kennedy elaborated: 'The physics demanded that the chambers were made of aluminium, with walls not thicker than 6mm, otherwise the particles would not reach the chambers fitted within them. Twelve of these were mounted on each end of the detector, with only 3mm clearance between them; the welding had to be perfect, and distortion kept to the very minimum, A lot was learnt which has enabled us to offer our expertise for other major projects.
