“…As seen in Table 3.1, its average energy lost is relatively high. Its scintillation properties have been used for a new kind of gas scintillator neutron detectors [33]. Moreover, as it will be shown in Figure 3.4 is a fast gas.…”

The aim of this thesis is to show the potential of this technique as an alternative to 3 He-based PSD for Neutron Scattering Science (NSS) instruments. Relatively high detection eciency together with large scale production capabilities show its capacity. ' Chapter 5. Multi-Grid Detector capability were studied. Based on the ToT calculus, the CoG algorithm was study as a method to improve the spatial resolution of the detector along the wire dimension. This will be further studied in Section 7.2.2.

“…High density of Fluorine atoms makes the media sensitive to spin-dependent interactions [4]. Furthermore, CF 4 was reported as a good scintillator in the far UV [5], as well as in the UV and visible wavelength regions exhibiting fast scintillation and high photon yields [6][7][8]. These properties make CF 4 an attractive detection media in detectors with optical readout such as 2D position sensitive thermal neutron detectors [9] and TPCs for different purposes (e.g.…”

“…It has been reported that adding CF 4 to the noble gas can improve the secondary scintillation characteristics of the noble gases. Carbon-tetrafluoride (CF 4 ) is a heavy molecule that contains only low-Z atoms, and its sensitivity to gamma radiation is low [10]. To improve the sensitivity of the chamber detector while maintaining the n/g discrimination ability, we propose using Arþ CF 4 gas mixtures as detection media.…”

“…To improve the sensitivity of the chamber detector while maintaining the n/g discrimination ability, we propose using Arþ CF 4 gas mixtures as detection media. In addition, CF 4 is a fascinating gas scintillator, i.e., its emission spectrum ranges from the far-ultraviolet to the nearinfrared with a significant fraction in the visible region [10][11][12]. It has been reported that the secondary emission spectra from CF 4 based noble gas mixtures, e.g., ArþCF 4 or HeþCF 4 , are similar to that of pure CF 4 under X-ray and electron excitation in MicroPattern Gas Detectors (MPGDs) [13][14][15][16][17].…”
