Keywords: | Liquid xenon; Ionisation chamber; Gamma-ray detection | Issue Date: | 2002 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 477:1-3 (2002) 184-190 | Abstract: | A two-dimensional readout with metal strips deposited on both sides of a glass plate is investigated aiming to assess the possibility of its use in a liquid xenon ionisation chamber for positron emission tomography. Here, we present results obtained with an [alpha]-source. It is shown that position resolution of [less-than-or-equals, slant]1 mm, fwhm, can be achieved for free charge depositions equivalent to those due to [gamma]-rays with energy from 220 down to 110 keV. | URI: | https://hdl.handle.net/10316/4503 | DOI: | 10.1016/S0168-9002(01)01889-7 | Rights: | openAccess |
