Covid-19: TK continuing to work

  Thomas Keating continues to work: Staff who can work from home (Physicist, Designers etc) are doingso -  and our IT infrastructure (in particular, VPN's give remote access to our network, including CAD,electromagnetic and thermal analysis software as well as printing) is currently holding up well.  Colleagues who cut metal are practicing social distancing (our machines are well spread out, so 2M distance.... a broomhandle away) is possible and cleaning their hands alot... So Thomas Keating Ltd is operating surprisingly normally   The Physics Department in Cardiff is currently closed, so QMC Instruments is continuing to design, market and support our customer base, but n...

CubeSat mm-wave calibration loads ship to NASA Goddard

At the end of January, TK shipped two types of loads for mm-wave radiometer calibration:  An internal cone load - derived from the SWI instrument on ESA's Juice mission. In this case TK is a subcontractor to VDI, having alsodesigned and buit the from end optics of the protype CubeSat     .. and two loads derived from the warm pyramidal target on the MetOP-SG Ice Cloud Imager mission:     The latter can be seen in our TVAC chamber where the embeded Platinum Resistance Thermometers (PRTS) are being calibrate against four surounding SPRTs, to a precision at the 10mK level.    

MetOP-SG's MWS PFM radiometer On-Board Calibration Target undergoes final testing in Bern

TK has been developing in collaboration with the Institute of Applied Physics in Bern - for a number of years - the calibration target for EUMETSAT's MetOP-SG MWS radiometer. The ProtoFlight Model - (PFM) - the first one due to fly in space - has been undergoing successful final RF testing in Bern. In the pictures you can see the equipment used to make radiometric S11scattering measurements across the microwave sounder's bands - from 23 to 229 GHz. The target - whose temperature can be determined from embedded Platinum Resistance Thermometers to a few milliKelvin- is the black object to the top right. All S11 measurements are with the very tight -45dB monostatic reflectivity requirement - an...

TK apprentice Callum Barrett scoops Award

We are delighted that Callum Barrett, our new apprentice has won the Best Apprenticeship 2019 award given by the Rotary Club at a ceremony at Tanbridge House School.       Callum ....second from the left...

CEITEC's RapidScan HF-ESR bridge starts operation

With Quasi-Optics from TK and mm-wave sources and detectors from VDI, Petr Neugebauer's multi-frequency High Field ESR spectrometer is undergoing "first-light" (to use an astronomers term) testing.   With the dry magnet from Cryogenic Ltd nicely buried in the floor - and  elegant mounting structure and covering from colleagues in Brno - the Instrument is looking very impressive:     The frequency-independent Quasi-Optical Bridge has an unusual feature of having common path lengths in both the LO chain and source chain to the primary inductive-mode detector and phase reference - to minimisethe effect of source phase noise on the instrument's' sensitivity.    ...

High Q Resonator for Qinetiq delivered to NPL

Under guidance from Bob Clarke and Andrew Gregory from NPL's Electromagnetic & Electrochemical Technologies Department, we have designed a high Q resonator for materials measurement at mm-wavelengths for Qinetiq plc. Using a precision-turned high conductivity spherical mirror and carefully adjusted coupling holes, the resonator will allow precision measurements of the complex permitivity of low loss materials. Fine adjustment of the flat sample mirror is provided.   The two waveguide ports - seen below - are   connected to a VNA to display the resonance.
