    Production of Radiopure Materials & Additive Manufacturing Industrial Applications
    Presentation

    Micromesh Gas Structures (Micromegas) as readout of gaseous Time Projection Chambers (TPCs) are being considered in experiments investigating rare phenomena, like the nuclear double beta decay, solar axion detection and low-mass dark matter interactions, due to their good performance on spatial and energy resolution and operation stability. In addition, as they are potentially made mainly of...

    Presentation

    The quest to directly detect dark matter and unravel the nature of neutrinos has driven the development of experimental techniques with unprecedented sensitivity, placing extreme demands on detector-material-induced backgrounds. As a result, the choice of construction materials, particularly those in direct contact with the target medium, has become a critical limiting factor. Electroformed...

    Presentation

    Materials with extremely low content of radioactive impurities are required for the construction of successful rare-event detectors, where constraints on naturally occurring radionuclides such as 232Th and 238U typically fall in the microBq/kg range or lower, corresponding to parts-per-trillion (ppt) or parts-per-quadrillion (ppq) concentrations. These levels are several orders of magnitude...

  4. 70. Ultra pure copper electroforming at Boulby deep underground laboratory

    Presentation

    High purity copper is an attractive material choice for low background detector construction, due to its commercial availability and lack of long-lived radioisotopes. Despite this, copper can still represent an important background, with impurities from the ore, implanted during manufacture or from cosmogenic activation. Underground additive-free electroforming provides a method to produce...
