TK to calibrate the ALMA Telescope PDF Print E-mail
Latest News from Terahertz

Against full international competion, TK has been awarded a 1.25 Million Euro contract to manufacture 67
ambient and warm Calibration Loads for the ALMA telescope by ESO, the European Organisation for
Astronomical Research in the Southern Hemisphere.

Operating in the Atacama desert in Chile the ALMA telescope will look at galaxy formation in the early
Universe and local star and planet formation in our local galaxy, by observing radiation in between 30 and
1000 GHz. ALMA's radiation receivers need to be continuously calibratedand TK's order is to provide the
accurately known thermal reference targets, from which any astronomical object's temperature can be
interpolated.

The Calibration Loads are based upon very low S11 reflectivity cones. The design - developed with
Dr Axel Murk at the IAP in Bern - has required the development of some precision mould for casting
the microwave absorbers to sub-100uM precision.

Obama's simulus funds reach TK PDF Print E-mail
Latest News from Terahertz

Thomas Keating has received an order from the US Deparment of Energy's Pacific National Laboratory
in Richland, WA to build a copy of Graham Smith's HiPER 94 GHz pulse Electron Spin Resonance
specrometer optics.  Due for delivery in the late summer of 2010 the 400 K USD order, funded
from the 2009 Obama simulus package, will provide PNL with a step change in their ESR facilities
when its comes on stream in early 2011.

ESA has released first light pictures of Planck's - the third generation of
Cosmic Microwave Background anisotropy space instruments - first
operational scan.

The false colour image below shows a comparison of a small area of
space whose minute temperature variation away from 2.7K are
displayed at 70 GHz (from the Low Frequency Instrument, for which
we did nothing) and the High Frequency Instrument (HFI). The match is
very good, indicating that both instruments are performing well.

TK was, with others, involved in the design of the HFI antenna array
and manufactured the horns - shown in the image below.

Dr Graham Bell joined TK as a Project Scientist PDF Print E-mail
Latest News from Terahertz

Dr Graham Bell,  who recently completed his PhD thesis under
Prof Richard Hills at the MRAO in Cambridge, has joined Thomas Keating
as a Project Scientist. His PhD centred on the design of the
HARP-B optics - a 16  channel radiometer operating from 325 to 375 Ghz 
on the JCMT in Hawaii.

In additional to his observational interests in Thz Astronomy, he is
also a keen Glider Pilot.

u Tolerance Milling Calibration PDF Print E-mail
Latest News from Terahertz

In late March, our three high speed CNC milling machines were two colour interferometrically re-calibrated
by CD Measurements Ltd.

Our new factory provides a much more stable environment for these machine tools, and very tight tolerances
were achieved, as follows

 

DMG 50 V:   1.46 uM in X, 1.37 uM in Y and 1.65 uM in Z

The Collapse of the Pound PDF Print E-mail
Latest News from Terahertz

Alex -  the  greedy bank featured in the Torygraph Newspaper in the UK is pointing out a painful truth: As Buffett
say, when the tide goes out, you discover who has swimming trunks on.

The UK economy - living of an overheated housing market and Financial Services income - both who
have past their high water mark for this cycle - has no swimming trunks.  Hence the collapse of the £.

Bad news for us when we go on holiday abroad, but good for TK and QMC Instruments' exports. We are
less expensive now...

The Pound has now fallen further since these Nov graphs were plotted.
