Great to see this image Magnetic swirl: a view of the M87 supermassive black hole in polarized light. The lines mark the orientation of the polarization, which is related to the magnetic field around the shadow of the black hole. (Courtesy: EHT Collaboration) in Physics World showing magnetic fied local to the vast Black Hole at the centre of our Galaxy, measured at 230 GHz We have supplied polarizing grids to a number of the institutions involved in the Event Horizon Telescope (EHT) Collaboration
In early September we were delighted to be able to provide Thermal Vacuum Testing (TVAC) in our Class 10,000 Clean Room for space detector for UK company Photek: Photek is a specialist manufacturer of vacuum based tubes and camera systems for photon detection. With thermal cycling following the follwing path:
DNP requires the marriage of high magnetic fields and intense mm-wave radiation. Metal mirrors can distort the very homogenous fields required, so thin metal film coated dielectric mirrors can bring significant performance advantages: As part of building a quasi-optical probe delivering microwave power for a sample buried deep in a highly homogenous superconducting magnet, we have been making full use of our precision Bostomatic high-speed milling machine: The recently arrived Swiss-made Lehmann AG two-axis table and 5-Axis Heidenhein TNC640 controller has allowed us to machine the Macor glass cerami with a precision elliposodal form. A short video can be seen below {mp4}Maco...
Notwithstanding the strange times we are living in, TK continues to invest in capital equipment to better serve ourclients : Pictured above is an almost new Doosan Puma GT3100 CNC 2 CNC lathe being unloaded. 'Almost new' in that we bought it at Auction (an interesting experience - like Ebay, but with a lot more money attached). The manufacturing dates on the plate is September 2019 and with only 108 hours on the 'clock', it has only really be run in.
We are delighted to have finished making - some two weeks after the steel arrived and now trialed - our first Personal Protection Equipment (PPE) injection mould for new client Air Control Entech to provide the frame of a face visor: Thanks to a lot of hard work by a lot of people, especially Simon Duke, our Toolroom Manager... Pictured below is Apprentice Zac Feeman with a trialled part in his hands... as well as one on his head. and a video of our customer running mould running can be seen here A snipped of the mould tool design can be seen here and video of programming the tool paths and our high speed Bostomatic CNC milling machining cutting the form in...
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...
