14 Nov 2010 | Abstract: | Muon tomography based on the measurement of multiple scattering of
atmospheric cosmic ray muons is a promising technique for detecting and imaging
heavily shielded high-Z nuclear materials such as enriched uranium. This
technique could complement standard radiation detection portals currently
deployed at international borders and ports, which are not very sensitive to
heavily shielded nuclear materials. We image small targets in 3D using $2 imes
2 imes 2$ mm^3 voxels with a minimal muon tomography station prototype that
tracks muons with Gas Electron Multiplier (GEM) detectors read out in 2D with
x-y microstrips of 400 micron pitch. With preliminary electronics, the GEM
detectors achieve a spatial resolution of 130 microns in both dimensions. With
the next GEM-based prototype station we plan to probe an active volume of ~27
liters. We present first results on reading out all 1536 microstrips of a $30
imes 30$ cm^2 GEM detector for the next muon tomography prototype with final
frontend electronics and DAQ system. This constitutes the first full-size
implementation of the Scalable Readout System (SRS) recently developed
specifically for Micropattern Gas Detectors by the RD51 collaboration. Design
of the SRS and first performance results when reading out GEM detectors are
presented. | Source: | arXiv, 1011.3231 | Services: | Forum | Review | PDF | Favorites |
