Abstract Flexible printed cables and circuitry based on copper-polyimide materials are widely used in experiments looking for rare events due to their unique electrical and mechanical characteristics. However, past studies have found copper-polyimide

International audience; Experimental efforts of the last decades have been unsuccessful in detecting WIMPs (Weakly Interacting Massive Particles) in the 10-to-10$^4$ GeV/$c^2$ range, thus motivating the search for lighter dark matter. The DAMIC (DArk

Mass spectrometric analyses of high performance polymers to assess radiopurity as ultra low background materials for rare event physics detectors

Autor: Jay W. Grate, Sonia Alcantar Anguiano, I. J. Arnquist, Eric W. Hoppe, Maria Laura di Vacri, Khadouja Harouaka, Mary Bliss

The mass concentrations of 232Th and 238U in several strong, unfilled, high performance polymers are reported as measures of their radiopurity. Highly radiopure polymers are required as dielectric materials in the construction of rare event physics d

The preparation of novel wrapped carbon nanotubes poly(4-vinylpyridine)/methyl trioxorhenium based heterogeneous catalysts has been reported by two different procedures: a) the wrapping by grinding of multiwall carbon nanotubes with pre-formed adduct
