Introduction Access to radiometals suitable for labeling novel molecular imaging agents requires that they be routinely available and inexpensive to obtain. Proximity to a cyclotron center outfitted with solid target hardware, or to an isotope generator for a radiometal of interest is necessary, both of which can be significant hurdles in availability of less common isotopes. Herein, we describe the production of 44Sc, 68Ga, 89Zr, 86Y and 94mTc in a solution target which allows for the production of various radiometallic isotopes, enabling rapid isotope-biomolecule pairing optimization for tr

Introduction Short-lived isomer 83mKr (T½ = 1.83 h) is an ideal calibration source in several low-energy experiments like or KATRIN (determining the neutrino rest mass, monitoring high voltage stability and investigation of the main spectrometer properties) or XENON (detection of the dark matter). The isomer 83mKr is formed by decay of 83Rb (T½ = 86.2 d) that can be produced predominantly via the reaction 84Kr(p,2n)83Rb by irradiation of natKr (57 % abundance of 84Kr).

Strontium-82 (t1/2 = 25.5 d) is one of the medical isotopes produced on a large scale at the Isotope Production Facility (IPF) of the Los Alamos National Laboratory (LANL), employing a high intensity 100 MeV proton beam and RbCl targets. A constant increase in the 82Sr demand over the last decade combined with an established thermal limit of molten RbCl salt targets [1,2] has challenged the IPF’s world leading production capacity in recent years and necessitated the consideration of low-melting point (39.3 °C) Rb metal targets.

iThemba LABS, in the South African Isotope Facility (SAIF) project, proposes to produce radioactive ion beams by the fission of uranium. A natural way to fission uranium is to use high-intensity proton beams from a cyclotron. However, neutron-induced fission gives enhanced production of neutron-rich fission fragments compared to proton-induced fission, thus there is a need to find efficient ways of producing neutrons from protons. Beryllium targets have been suggested, but increasing the proton beam current to achieve higher fission rates could lead to cooling problems. Cooling might be achiev

Introduction Technetium-99m, supplied in the form of 99Mo/99mTc generators, is the most widely used radioisotope for nuclear medical imaging. The parent isotope 99Mo is currently produced in nuclear reactors. Recent disruptions in the 99Mo supply chain [1] prompted the development of methods for the direct accelerator-based production of 99mTc. Our approach involves the 100Mo(p,2n)99mTc reaction on isotopically enriched molybdenum using small medical cyclotrons (Ep ≤ 20 MeV), which is a viable method for the production of clinically useful quantities of 99mTc [2].

Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 273-291).<br>In this thesis I discuss the first measurement of the beam-target double-spin asymmetry ALT for charged pion electroproduction in deep inelastic electron scattering on a transversely polarized 3He target. These data were taken between October 2008 to February 2009 using a 5.9 GeV polarized electron beam at Thomas Jefferson National Accelerator F

Single phase and boiling batch water targets are the most common designs for the cyclotron production of 18F via the 18O(p,n)18F reaction. Thermosyphon targets have design and operating characteristics which enable higher power operation than conventional boiling targets of like size. Experimental thermosyphon target systems demonstrated the feasibility of high intensity irradiation via bottom pressurized operation. An effective experimental characterization platform was developed and utilized in parallel with computational modeling efforts to further improve designs. A control strategy was al

Since its discovery in 1896, radioactivity has been used in various application areas of physics. In particular, it was immediately clear its potential use in life sciences. In particular, it is actually used in metabolic radiotherapy, which uses radionuclides labelled to suitable molecules (i.e. radiopharmaceuticals). This is a practice well established and successful in the fight against cancer and other diseases. Together with the well-known radionuclides used in medicine, the attention is now focused one the ones of next generation. One of these is rhenium-186g, which is currently used in

T2K est une expérience de neutrinos à longue ligne de base à base d'accélérateurs au Japon. Le but principal de l'expérience T2K est la recherche d'une violation de la PC dans le secteur du lepton en mesurant l'apparence (anti)neutrino des électrons dans un faisceau muon (anti)neutrino. Le flux (anti) neutrino initial est produit par les désintégrations des hadrons qui proviennent des interactions et des ré-interactions d'un faisceau de protons de 30 GeV avec une cible en graphite de 90 cm de long. La connaissance du flux de neutrinos T2K est limitée en raison des grandes incertitudes liées à

Aujourd’hui, les radio-isotopes sont fréquemment utilises en médecine, pour le diagnostic et la thérapie. Cependant, le développement constant de la médecine nucléaire provoque l’application de nouveaux radio-isotopes médicaux. La recherche sur leur production possible a grande échelle est la première étape d’un long processus d’études avant de pouvoir de les utilise dans des essais cliniques. Dans cette thèse, les voies de production ont été étudiées pour la formation de médicalement intéressants 43Sc, 44m,gSc, 47Sc, 97Ru et 105Rh en utilisant de cyclotrons.

This study examines how Media Logic of YouTube and Twitch affects individual creators who works with creating content on the two platforms. It touches upon the different structures of Media Logic that exists over social media platforms and a little bit on how they have changed over the years. Most importantly it examines what a content creators work process and structure looks like and how that is affected by the different Media Logic structures. This subject is original since there is not previously made another likewise study around this particular subject. This not only makes it an explorat

Trans-complementation of gpE1/gpE2 allows recovery of infectious Hepatitis C virus Although observed for other members of the Flaviviridae including bovine diarrea virus and Kunjin virus, trans-complementation of replication-defective replicons was never observed for hepatitis C virus (HCV). This suggested an isolated and independent nature of the HCV replication complexes, with little or not exchange of factors between them. In particular, HCV non structural proteins seem to remain associated to their respective complexes and may not be able to access other complexes. In the present wo
