Spot size measurements in the Eli-NP compton gamma source

A high brightness electron Linac is being built in the Compton Gamma Source at the ELI Nuclear Physics facility in Romania. To achieve the design luminosity, a train of 32 bunches with a nominal charge of 250 pC and 16 ns spacing , will collide with the laser beam in the interaction point. Electron beam spot size is measured with an OTR (optical transition radiation) profile moni-tors. In order to measure the beam properties, the optical radiation detecting system must have the necessary accu-racy and resolution. This paper deals with the studies of different optic configurations to achieve the magnifica-tion, resolution and accuracy desired considering design and technological constraints; we will compare several configurations of the optical detection line to justify the one chosen for the implementation in the Lina

Optical issues for the diagnostic stations for the ELI-NP compton gamma source

A high brightness electron Linac is being built in the Compton Gamma Source at the ELI Nuclear Physics facility in Romania. To achieve the design luminosity, a train of 32 bunches, 16 ns spaced, with a nominal charge of 250 pC will collide with the laser beam in the interaction point. Electron beam spot size is measured with optical transition radiation (OTR) profile monitors. In order to measure the beam properties, the optical radiation detecting system must have the necessary accuracy and resolution. This paper deals with the studies of different optic configurations to achieve the magnification, resolution and accuracy in order to measure very small beam (below 30 μm) or to study the angular distribution of the OTR and therefore the energy of the beam. Several configurations of the optical detection line will be studied both with simulation tools (e.g. Zemax) and experimentally. The paper will deal also with the sensibility of optic system (in terms of depth of field, magnification and resolution) to systematic error

Beam diagnostics for charge and position measurements in ELI-NP GBS

The advanced source of Gamma-ray photons to be built in Bucharest (Romania), as part of the ELI-NP European Research Infrastructure, will generate photons by Compton back-scattering in the collision between a multi-bunch electron beam and a high intensity recirculated laser pulse. An S-Band photoinjector and the following C-band Linac at a maximum energy of 720MeV, under construction by an European consortium (EurogammaS) led by INFN, will operate at 100Hz repetition rate with trains of 32 electron bunches, separated by 16ns and a 250pC nominal charge. The different BPMs and current transformers used to measure transverse beam position and charge along the LINAC are described. Design criteria, production status and bench test results of the charge and position pickups are reported in the paper, together with the related data acquisition systems

Cardiac biomarker testing in the clinical laboratory: Where do we stand? General overview of the methodology with special emphasis on natriuretic peptides

Diagnosis of heart failure (HF) is not based on a single test, but on a combination of history, physical examination and appropriate investigations. For these reasons, the accuracy of diagnosis by clinical means alone is often inadequate, especially in the early, asymptomatic stages of the HF. Thus, there is an increasing interest in the development of new cardiovascular biomarkers and, consequently, a great number of laboratory tests have recently been proposed for their assay. The aim of this article is to provide a general overview on the biomarkers, recommended by international guidelines, for the diagnosis, risk stratification, and follow-up of patients with HF. Cardiac natriuretic peptides and in particular the B-type related peptides, which are considered to be the first line biomarker for HF by international guidelines, will be discussed with special emphasis

Adubação nitrogenada no milho no Oeste do estado do Pará.

O objetivo deste trabalho foi avaliar a resposta do milho (Zea mays) a doses de nitrogênio (N) e épocas de aplicação do fertilizante nitrogenado no oeste do Estado do Pará. O experimento de campo foi realizado em Latossolo Amarelo distrófico textura muito argilosa do Município de Belterra, Estado do Pará. O delineamento experimental foi o de blocos ao acaso com três repetições. Os tratamentos consistiram no arranjo fatorial 5 x 3, correspondendo a cinco doses de N (0, 30, 60, 90 e 120 kg ha?1; fonte: ureia) e três parcelamentos [(i) 100% no sulco de semeadura, (ii) 50% no sulco de semeadura e 50% em cobertura aos 35 dias da semeadura, (iii) 30% no sulco de semeadura e 70% em cobertura aos 35 dias da semeadura]. A produtividade de grãos de milho aumentou até a dose de 120 kg ha?1 de N e foi maior com o parcelamento da adubação nitrogenada do que com a aplicação total de N na semeadurabitstream/item/82197/1/Oriental-BDP84.pd
