Tumor Therapy with Heavy Ions at GSI Darmstadt
In comparison to conventional photon therapy heavy-ion beams offer favourable conditions for the treatment of deep-seated local tumors. The physical depth-dose distribution in tissue is characterized by a small entrance dose and a distinct maximum (Bragg peak) near the end of range with a sharp fall-off at the distal edge. The well-defined range and the small lateral beam spread make it possibl...
متن کاملHeavy Ions Theory Review *
The advent of collider energies to heavy–ion physics is leading to a profound change in the field. The new tools available, specially the access to the large transverse momentum part of the spectrum, allow for an unprecedented characterization of the high–density state created in such collisions. Accordingly, the traditional goal of producing a Quark-Gluon Plasma, the deconfined state of quarks...
متن کاملQCD and Heavy Ions
This short paper is an attempt to describe a theorist’s view of the goals of relativistic heavy ion program which has just entered the collider era. These goals are centered around understanding the properties and the critical behavior of Quantum Chromo–Dynamics (QCD) in the non–linear regime of high color field strength and high parton density. Some of the current theoretical challenges are hi...
متن کاملDetection of Energetic Heavy Ions
The delta-ray theory of track structure, applied earlier to such 1-or-more hit detection systems as the inactivation of dry enzymes and viruses, the NaI(Tl) scintillation counter, and nuclear emulsion, is extended to the silver activated phosphate glass dosimeter, the LiF thermoluminescent dosimeter, the creation of free radicals in solid biological substances, solid and liquid organic scintill...
متن کاملInterphase Death of Chinese Hamster Ovary Cells Exposed to Accelerated Heavy Ions
Introduction: Heavy ions are nucleus of elements of iron, argon, carbon and neon that all carry positive electrical charges. For these particles to be useful in radiotherapy they need to accelerated to high energy by more than thousand mega volts. Also the cosmic environment is considered to be a complicated mixture of highly energetic photons and heavy ions such as iron. Therefore, the health ...
