    The butter paste development with red beet powder based on the butter with the addition of skimmed milk powder. Dairy base of the butter paste is includes the complex of plant food additives such as flaxseed, inulin and red beet powder. It was established that should give preference to the use of red beet criopowder for increasing mineral composition of the butter paste. Selected plant additives are increasing the mineral content in the finished product, the most – the content of iron, potassium, calcium, chlorine. The content of toxic elements such as lead, cadmium, arsenic, mercury and zinc in the finished butter paste were not found, and the content of copper and iron in the normal range.  Разработана технология масляной пасты с порошком из красной столовой свеклы на основе сливочного масла с добавлением сухого обезжиренного молока. К молочной основе входит комплекс растительных пищевых добавок: семяна льна, инулин и порошок из свеклы. Установлено, что для повышения минерального состава масляной пасты необходимо отдавать предпочтение использованию порошка из красной свеклы, полученного криогенным методом сушки. Выбраный комплекс растительных пищевых добавок повышает содержание минеральных веществ в готовом продукте, больше всего – содержание железа, калия, кальция, хлора. Содержание токсичных элементов таких как свинец, кадмий, мышьяк, ртуть и цинк в готовой масляной пасте не обнаружено, а содержание меди и железа находится в пределах нормы.Розроблено технологію масляної пасти з порошком із червоного столового буряка на основі вершкового масла з додаванням сухого знежиреного молока. До молочної основи входить комплекс рослинних харчових добавок: насіння льону, інулін та порошок із буряка. Встановлено, що для виробництва масляної пасти з порошком із столового буряка з покращеним вмістом мінеральних речовин слід віддавати перевагу використанню порошку, який отримано кріогенним методом сушіння. Обраний комплекс рослинних харчових добавок підвищує вміст мінеральних речовин в готовому продукті, найбільше – вміст феруму, калію, кальцію, хлору. Вмісту токсичних елементів, таких як свинець, кадмій, миш’як, ртуть та цинк – у готовій масляній пасті не виявлено, а вміст міді та заліза – в межах норми

    This paper reports on work undertaken, in collaboration with ITC-IRST at Trento, to characterize and test the silicon photomultiplers produced by them, with a view to their future application in high energy and astrophysics experiments. Results of static and dynamic measurents with various IRST devices under controlled climatic conditions, together with measurements with SiPMs from other distributors are reported and discussed with emphasis on progress in the understanding of operational principles and the reduction of noise. Results from the test beam application of the SiPMs are also reported and future plans are discusse

    Development and tests of a new prototype detector for the XAFS beamline at Elettra Synchrotron in Trieste

    Get PDF
    The XAFS beamline at Elettra Synchrotron in Trieste combines X-ray absorption spectroscopy and X-ray diffraction to provide chemically specific structural information of materials. It operates in the energy range 2.4-27 keV by using a silicon double reflection Bragg monochromator. The fluorescence measurement is performed in place of the absorption spectroscopy when the sample transparency is too low for transmission measurements or the element to study is too diluted in the sample. We report on the development and on the preliminary tests of a new prototype detector based on Silicon Drift Detectors technology and the SIRIO ultra low noise front-end ASIC. The new system will be able to reduce drastically the time needed to perform fluorescence measurements, while keeping a short dead time and maintaining an adequate energy resolution to perform spectroscopy. The custom-made silicon sensor and the electronics are designed specifically for the beamline requirements.Comment: Proceeding of the 6YRM 12th-14th Oct 2015 - L'Aquila (Italy).

    Accelerator experiments with soft protons and hyper-velocity dust particles: application to ongoing projects of future X-ray missions

    Full text link
    We report on our activities, currently in progress, aimed at performing accelerator experiments with soft protons and hyper-velocity dust particles. They include tests of different types of X-ray detectors and related components (such as filters) and measurements of scattering of soft protons and hyper-velocity dust particles off X-ray mirror shells. These activities have been identified as a goal in the context of a number of ongoing space projects in order to assess the risk posed by environmental radiation and dust and qualify the adopted instrumentation with respect to possible damage or performance degradation. In this paper we focus on tests for the Silicon Drift Detectors (SDDs) used aboard the LOFT space mission. We use the Van de Graaff accelerators at the University of T\"ubingen and at the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg, for soft proton and hyper-velocity dust tests respectively. We present the experimental set-up adopted to perform the tests, status of the activities and some very preliminary results achieved at present time.Comment: Proceedings of SPIE, Vol. 8443, Paper No. 8443-24, 201

    The Heavy Photon Search test detector

    Get PDF
    The Heavy Photon Search (HPS), an experiment to search for a hidden sector photon in fixed target electroproduction, is preparing for installation at the Thomas Jefferson National Accelerator Facility (JLab) in the Fall of 2014. As the first stage of this project, the HPS Test Run apparatus was constructed and operated in 2012 to demonstrate the experiment׳s technical feasibility and to confirm that the trigger rates and occupancies are as expected. This paper describes the HPS Test Run apparatus and readout electronics and its performance. In this setting, a heavy photon can be identified as a narrow peak in the e+e− invariant mass spectrum above the trident background or as a narrow invariant mass peak with a decay vertex displaced from the production target, so charged particle tracking and vertexing are needed for its detection. In the HPS Test Run, charged particles are measured with a compact forward silicon microstrip tracker inside a dipole magnet. Electromagnetic showers are detected in a PbW04 crystal calorimeter situated behind the magnet, and are used to trigger the experiment and identify electrons and positrons. Both detectors are placed close to the beam line and split top-bottom. This arrangement provides sensitivity to low-mass heavy photons, allows clear passage of the unscattered beam, and avoids the spray of degraded electrons coming from the target. The discrimination between prompt and displaced e+e− pairs requires the first layer of silicon sensors be placed only 10 cm downstream of the target. The expected signal is small, and the trident background huge, so the experiment requires very large statistics. Accordingly, the HPS Test Run utilizes high-rate readout and data acquisition electronics and a fast trigger to exploit the essentially 100% duty cycle of the CEBAF accelerator at JLab
