Title: | Modelling of an IR scintillation counter | Authors: | Fraga, M. M. F. R. Fraga, F. A. F. Policarpo, A. J. P. L. |
Keywords: | Gaseous scintillators; Infrared emissions | Issue Date: | 2000 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 442:1-3 (2000) 423-427 | Abstract: | A systematic study of the excitation and de-excitation mechanisms in ternary gas mixtures Ar+CO2+N2 is presented regarding the possibility of developing a proportional scintillation counter based on the detection of the infrared molecular emissions associated with the lowest vibrational states of molecules. The use of visible or near-infrared photons ([lambda]<1Â [mu]m) for applications like imaging and quality control of microstructure detectors has been reported. In view of these applications we analyse the processes leading to near-infrared emissions in pure argon and give an estimation of the number of photons emitted per electron, at several pressures, as a function of the charge gain. | URI: | https://hdl.handle.net/10316/4536 | DOI: | 10.1016/S0168-9002(99)01267-X | Rights: | openAccess |
