Surface flatness maps of one of our steering mirrors.
Dirty Assembly of our double stage auxiliary suspensions. Preparation of auxiliary suspension parts. New coil winding machine.
CAD drawing of our auxiliary suspensions (left) and the 100g monolithic suspensions (right). CAD drawing of the speedmeter setup, including vacuum tanks, seismic isolationstacks, bridge structure and some of the suspensions.
CAD model of our auxiliary suspensions designed by Jan and Russell At a visit Jan Harms shows us how to convert a S13 seismometer from vertical to horizontal operation. Russells nice mock-up of the auxiliary suspensions. Looks pretty scar ... eh, challanging.
Science selfie! 4 stage seismic isolation stack made out of 240kg of stainless steel, squeezed to less than 8cm in height. Four men, four 'corners'.
How to handle heavy steel plates? Right, - you need to screw on handles. Custom made Fluorel springs after Matthew cleaned them in the ultra sonic bath, cooked them 4 times for 2 hours and baked them for 3 days. The Speed-Meter corner of the cleanroom after the stainless steel sledge has been removed. Neil teaching Stefan how to mould good rubber for seismic isolation stacks.
Comparison of an old Garching prototype mirror (right) and a 1.6g mirror (left). First fringes of the 1m in-air test Sagnac interferometer. Fraser Campbell working on his 1m in-air test Sagnac interferometer.
Control room of the Glasgow 10m interferometer. One of the rare pictures of Stefan pretending to do some actual work. 270 degrees panorama of the Glasgow 10m prototype lab and the ERC Speed-Meter experiment (vacuum tanks on the left).
