Journal ArticleCalibration of Solid State Nuclear Track Detectors for rare event searchesKalliokoski, M; Levi, G; Maulik, A; Ostrovskiy, I; Patrizii, L; Pinfold, J; Sahnoun, Z; Sirri, G; Soluk, R; Staelens, M; Togo, V; Upreti, A<title>Abstract</title> <p>The calibration of the CR39^®and Makrofol^®Nuclear Track Detectors of the MoEDAL experiment at the CERN-LHC was performed by exposing stacks of detector foils to heavy ion beams with energies ranging from 340 MeV/nucleon to 150 GeV/nucleon. After chemical etching, the base areas and lengths of etch-pit cones were measured using automatic and manual optical microscopes. The response of the detectors as measured by the ratio of the track-etching rate over the bulk-etching rate, was determined over a range extending from their threshold at Z/<italic>β</italic>∼ 7 and ∼ 50 for CR39 and Makrofol, respectively, up to Z/<italic>β</italic>∼ 92.</p>JINST2025-03-0110580216Journal of Instrumentation2003P030141748-0221https://doi.org/10.1088/1748-0221/20/03/P030142309505National Science Foundation
