The SiD Detector is one of two detector designs for the future International Linear Collider (ILC) that were validated in 2012 SiD features a compact, cost-constrained design for precision Higgs and other measurements, and sensitivity to a…
We have designed, fabricated and tested a lens with chromatic aberration coefficient (Cc) of 1.0 mm, a 4.0 mm pole-gap and 2.0 mm bore that is wide enough to accommodate an anti-contamination system and an objective aperture. This lens…
The last energy-frontier lepton collider, LEP, established several limits that still hold today. A key one is the counting of three light neutrino species from the invisible decay width of the Z boson. From a collider calorimetry…
Metal oxide semiconductors have been thoroughly studied for gas sensing applications due to the electrical transduction phenomenon in the presence of gaseous analytes. The chemiresistive sensors prevalent in the applications have several…
Sensors for particle tracking detectors are required to provide a maximum active area in addition to fulfilling performance criteria concerning radiation hardness, charge collection and operating conditions (e.g. leakage current, depletion…
The high energy physics community recently gained access to the TPSCo 65 nm ISC (Image Sensor CMOS), which enables a higher in-pixel logic density in monolithic active pixel sensors (MAPS) compared to processes with larger feature sizes. To…
Future gravitational wave observation in space will demand improvement in the sensitivity of the local sensor for the drag-free control. This paper presents the proposal, design, and demonstration of a new laser interferometric sensor named…
Four Borehole Heat Exchangers (BHE) were installed at the BRGM Shallow Geothermal Research Facility (BRGM-SGRF) in Orl{\'e}ans, France. They are sixty meters deep and eight meters apart on a line. The facility is localized in the Parisian…
Organic glass scintillators are an interesting alternative to liquid scintillators, offering many advantageous characteristics with few drawbacks. In this paper we investigate the influence of light self-absorption in the organic glass…
We report on the test of a small scale, non-planar coil using non-insulated ReBCO tape wound on a 3D-printed aluminum support structure. A 3D-scan of the winding frame which was printed out of AlSi10Mg using selective laser melting, showed…
