RADON SURVEY IN SCHOOL AND ESTIMATION OF EFFECTIVE DOSE USING CORRECTED RADON CONCENTRATION

Autor: E. R. Lee, Yong-Jae Kim, Byung-Uck Chang

Publikováno v: Radiation Protection Dosimetry. 179:101-107

Radon exposure in schools is different from that in dwellings because the residence pattern is very different each other. So, when effective dose is calculated in schools, different approach should be considered from in dwellings. The aim of this stu

GEM-based TPC with CCD imaging for directional dark matter detection

Autor: E. R. Lee, D. Loomba, E. H. Miller, N. Phan, J. A.J. Matthews, R. J. Lauer

Publikováno v: Astroparticle Physics. 84:82-96

The world's leading directional dark matter experiments currently all utilize low-pressure gas Time Projection Chamber (TPC) technologies. We discuss some of the challenges for this technology, for which balancing the goal of achieving the best sensi

Imaging $^{55}$Fe Electron Tracks in a GEM-based TPC Using a CCD Readout

Autor: D. Loomba, N. Phan, E. R. Lee

Images of resolved 5.9 keV electron tracks produced from $^{55}$Fe X-ray interactions are presented for the first time using an optical readout time projection chamber (TPC). The corresponding energy spectra are also shown, with the FWHM energy resol

Low Threshold Results and Limits from the DRIFT Directional Dark Matter Detector

We present results from a 54.7 live-day shielded run of the DRIFT-IId detector, the world's most sensitive, directional, dark matter detector. Several improvements were made relative to our previous work including a lower threshold for detection, a m

Data are presented from the DRIFT-IId detector housed in the Boulby mine in northeast England. A 0.8 m^3 fiducial volume, containing partial pressures of 30 Torr CS2 and 10 Torr CF4, was exposed for a duration of 47.4 live-time days with sufficient p

The DRIFT Directional Dark Matter Experiments

Publikováno v: EAS Publications Series. 53:11-18

The current status of the DRIFT (Directional Recoil Identification From Tracks) experiment at Boulby Mine is presented, including the latest limits on the WIMP spin-dependent cross-section from 1.5 kg days of running with a mixture of CS2 and CF4 . P

The measurement of the direction of WIMP-induced nuclear recoils is a compelling but technologically challenging strategy to provide an unambiguous signature of the detection of Galactic dark matter. Most directional detectors aim to reconstruct the
