Heavy ion beam model for radiobiology.
An ad hoc model of energetic heavy ion beams, including secondary and tertiary particles, has been constructed for predicting radiobiological experiments. While the beam model is relatively primitive, it yields depth-dose and depth-radiobiological calculations in good agreement with experiment upstream of the Bragg peak. Beyond the peak, the model is somewhat coarse grained and seems to underes...
متن کاملAlpha Particle Emitter Radiolabeled Antibody for Metastatic Cancer: What Can We Learn from Heavy Ion Beam Radiobiology?
Alpha-particle emitter labeled monoclonal antibodies are being actively developed for treatment of metastatic cancer due to the high linear energy transfer (LET) and the resulting greater biological efficacy of alpha-emitters. Our knowledge of high LET particle radiobiology derives primarily from accelerated heavy ion beam studies. In heavy ion beam therapy of loco-regional tumors, the modulati...
متن کاملBeam Imaging Diagnostics for Heavy Ion Beam Fusion Experiments*
We are developing techniques for imaging beams in heavy-ion beam fusion experiments in the HIF-VNL in 2 to 4 transverse dimensions. The beams in current experiments range in energy from 50 keV to 2 MeV, with beam current densities from <10 to 200 mA/cm, and pulse lengths of 4 to 20 μs. The beam energy will range up to 10 MeV in near-future beam experiments. The imaging techniques, based on kapt...
متن کاملBeam Dynamics in Heavy Ion Fusion
for current multiplication, and it is there that the main challenges of beam dynamics are found. It is being studied in Europe, Russia, and Japan, and is discussed in ref. [1]. A standard design for heavy ion fusion drivers under study in the US. is an induction linac with electrostatic focusing at low energy and magnetic focusing at higher energy. The need to focus the intense beam to a fewmil...
متن کاملHeavy ion guide: beam transport and diagnostics
Our present plans for a heavy-ion guide system are based on developments at Argonne National Laboratory (ANL) [1]. For the heavy-ion guide, preselection of ions will be done using a superconducting solenoid similar to that being used now in the BigSol spectrometer. Earlier tests with a 1 m long gas cell at low input intensities (below 10 ion/sec) have been carried out at ANL with beams up to 4 ...
