“…Methyl iodide (CH 3 I) that dissociates efficiently in a discharge was used as an iodine precursor. There are examples of successful use of CH 3 I in somewhat similar experimental conditions [16,17]. Homogeneous and heterogeneous iodine atom recombination resulted in increase of I 2 content along the flow which is undesirable.…”

A transverse flow dc glow discharge in Ar/CH 3 I mixtures was modeled using a plug-flow approximation and plasma evolution was computed within a frame of reference moving with the gas. Reduced electric field as a function of transportation length was determined using the condition of a constant power density in the discharge. Cathode fall (CF) was found by comparing modeled and experimental discharge voltages. It was shown that conditions in the plasma column are nearly optimal for iodine atoms production with the lowest required energy and larger energies observed in the experiment are due to energy loss in the CF. In the experiment, concentrations of iodine molecules were measured downstream of the discharge using laser-induced fluorescence. Iodine flow at the exit of the discharge generator consisted of 80-90% of iodine atoms and only of 10-20% of iodine molecules. A good agreement between modeled and measured concentrations was found.

We study the possibility of extracting geometric information on the shape of the extra dimension from four-dimensional data such as the mass of the Kaluza-Klein (KK) mode. Assuming one compact extra dimension whose geometry can be considered as perturbations in the flat background, we show that if there is a Z 2 symmetry in the extra dimension, for example the KK parity in models with Universal Extra Dimensions, then the warp factor in the metric is completely determined by the KK mass alone. Without KK parity, additional information depending on the boundary conditions is needed to fully reconstruct the metric, even though such information may be experimentally challenging to obtain. The case in a general background geometry is also considered.
