Large-area, high-precision drift chambers, based on the “jet cell” concept, have been developed for the muon spectrometer of the ATLAS experiment at LHC. Emphasis is placed on the control and ...reduction of systematic error in the drift measurement and in the mechanical construction. Results of measurements on prototypes are given. These indicate that a global precision of
σ ≲ 70 μm is achievable for large-area chambers.

Heterocyclic compounds containing atoms of the elements such as nitrogen, sulfur and oxygen as ring members are commonly used in various fields of industry as analytical reagents, ligands, dyestuffs, ...pharmaceutical substances and bioindicators.
In this study 5-(Quinoline-2-ylidene)-1,3-diethyl-2-thiobarbituric acid have been synthesized via Knoevenagel condensation reaction, the product solutions were prepared 10 −3 − 10 −5 M in CHCI 3, THF, MeOH, DMF and DMSO. UV/VIS spectra recorded and then compared at each other. Absorbance of the solutions were measured at 200 – 300 nm. The maximum absorbance value increased and a new absorption appeared at 400 – 500 nm. The samples were excited at 337 nm in order to measure fluorescence. The maximum emission was observed in MeOH at 398 nm. These values increased by time; therefore, the samples were not stable in solution state.
