51. Investigation of the Ordering of Porous Anodic Alumina Formed by Anodization of Aluminum in Selenic Acid.

Abstract

The formation of porous alumina by galvanostatic anodization in selenic acid has been investigated. The influence of the electrolyte concentration on the morphological features and the self-ordering behavior of the porous oxide film has been studied. The best pore arrangement is obtained upon anodization in 0.5 M H2SeO4. Using chronopotentiometry, gravimetric analysis and FESEM it is shown that the highest degree of pore ordering is caused by an optimal combination of the two mechanisms that lead to pore initiation: mechanical instability and field-assisted dissolution. In addition, by means of Raman spectroscopy it is found that the optical properties of porous alumina anodized in selenic acid do not exhibit parasite effects due to electrolyte incorporation during anodization. Hence, these templates are of great interest to fabricate and investigate functional nanostructures for optoelectronics. [ABSTRACT FROM AUTHOR]

Abstract

The developed software and technical complex represents a mobile working place designed to support the work of radiation safety experts in case of emergencies, when leaving for the place of accident. It comprises required databases on normative documents in the radiation safety area; enquiry databases on objects, the personnel and equipment of emergency-rescue teams (ERT) from FAAE of Russia; the bank of electronic maps; computer systems for operative forecast and radiation environment measurement; the system to define geographical coordinates as well as a wide set of communication links to accept and transfer the data. The software and technical complex is implemented on the base of a portable IBM-compatible computer. The technical complex is also equipped by a dose rate sensor to run field radiation measurements. Geographical reference to the dose rate measurements is performed via GPS-receiver. Basic objectives solved by tools of the present mobile complex are as follows - information and analytical support for radiation safety experts, express simulation of radiation environment in the place of accident accompanying by radionuclide release, on-site dose rate measurement and retrieval of data on electronic maps, preparation of on-line required documents, forecasts and recommendations, operative communication and data transfer provision for RF FAAE crisis centers.

Abstract

Multianode gas counter is used to measure beam intensity in ionization mode and profiles in proportional mode at a new INR RAS proton irradiation facility. A special model is created in COMSOL to simulate operational characteristics of this counter. A program for data acquisition and processing is based on LabVIEW. Operational characteristics of the counter and experimental results of beam measurements are presented. Upgrade of the existing software and hardware is discussed., Proceedings of the 26th Russian Particle Accelerator Conf., RUPAC2018, Protvino, Russia

57. Electrodynamic characteristics of RF-deflector for bunch shape monitor

Abstract

Bunch shape monitors, based on a transverse RF-scanning of secondary electrons, are used for measurements of particles longitudinal distribution in bunches at different linear ion accelerators. The phase resolution of such monitors depends crucially on accuracy of fabrication and tuning of RF-deflector, thus preliminary simulations of its electrodynamic characteristics are of importance for subsequent commissioning of the monitor. Simulations of some basic operational electrodynamic parameters and results of experimental measurements are presented., Proceedings of the 25th Russian Particle Accelerator Conf., RuPAC2016, St. Petersburg, Russia
