ABSTRACT: IR camera systems can be used for reflectographic analyses to detect and visualize underdrawings in paintings. Five technologies have been compared: CCD Si, FPA InGaAs, FPA HgCdTe and InSb detectors, and a vidicon tube. The comparison has been performed studying the relative contrast measured on homogeneous pictorial layers in infrared regions between 800 and 5000 nm. This comparison was completed through measurements of spectral transmittance (400–2500 nm) made with a spectrometer. The results have been related to the kind of pigment and of medium and to the thickness of the layer. All the systems have been tested also on the field, on paintings belonging to different museums. Some results are discussed.Infrared Physics & Technology 05/2013;

ABSTRACT: Visible and near-infrared properties of optically thick ceria ceramics encountered in solar-driven thermochemical cycles are determined in the wavelength range 0.35-2 µm by employing a novel methodology. The methodology consists of an analytical solution based on the modified two-flux approximation and the Monte Carlo ray-tracing method. The analytical solution is used to identify transport scattering albedo from normal-hemispherical reflectance of optically thick samples. The Monte Carlo ray-tracing method is used to obtain transport scattering coefficient in the near-infrared wavelength range 0.9–1.4 µm from bi-normal narrow-cone transmittance. Mie theory is employed to obtain transport scattering coefficient in an extended spectral range. Further, the index of absorption of ceria (cerium dioxide) is estimated by the additive relation for optically soft materials in a short-wave part of the near-infrared range. The proposed methodology is suitable for problems where traditional identification procedures have limited applicability because of highly scattering, optically thick materials and unknown index of absorption in the spectral range of weak absorption.Infrared Physics & Technology 01/2013; 57:101-109.

ABSTRACT: The electrical design of different components of 1 MW, 170 GHz gyrotron such as, magnetron injection gun, cylindrical interaction cavity and collector and RF window is presented in this article. Recently, a new project related to the development of 170 GHz, 1 MWgyrotron has been started for the Indian Tokamak. TE34,10 mode is selected as the operating mode after studied the problem of mode competition. The triode type geometry is selected for the design of magnetron injection gun (MIG) to achieve the required beam parameters. The maximum transverse velocity spread of 3.28% at the velocity ratio of 1.34 is obtained in simulations for a 40 A, 80 kV electron beam. The RF output power of more than 1 MW with 36.5% interaction efficiency without depressed collector is predicted by simulation in single-mode operation at 170 GHz frequency. The simulated single-stage depressed collector of the gyrotron predicted the overall device efficiencies >55%. Due to the very good thermal conductivity and very weak dependency of the dielectric parameters on temperature, PACVD diamond is selected for window design for the transmission of RF power. The in-house developed code MIGSYN and GCOMS are used for initial geometry design of MIG and mode selection respectively. Commercially available simulation tools MAGIC and ANSYS are used for beam–wave interaction and mechanical analysis respectively.Infrared Physics & Technology 12/2012; 57:1-7.
