Europe/Rome 2021-10-04 08:00:00 2021-10-08 22:00:00 Joint ICTP-IAEA Virtual Workshop on Atomistic Modelling of Radiation Damage in Nuclear Systems | (smr 3573) An ICTP-IAEA Virtual Meeting This virtual workshop will assist Ph.D. students and early-career researchers in developing a qualitative and quantitative understanding of the atomistic modelling of radiation damage on materials, both for existing fission and proposed fusion reactors. Atomistic modelling is the simulation of the behaviour of complex systems by explicitly taking its smallest constituent parts into account. In the context of radiation damage in nuclear materials, these simulations involve the bulk and surface atoms of reactor components and their interactions with energetic neutrons and plasma in the form of free atoms, molecules and ions. The computational techniques employed include molecular dynamics, rate theory equations, density functional theory, and a variety of Monte Carlo methods; this Workshop provides an introduction to some popular software used to implement these techniques, with practical sessions on the free packages LAMMPS and SRIM. More details are available at IAEA web site: https://amdis.iaea.org/workshops/ictp-2021 Topics: Irradiated material: defect and cascade production Damage dose-rate, energies, and atomic displacement Neutron-induced material defect simulation Theoretical modelling of radiation effects Plasma-surface interaction: erosion and surface-evolution studies Hydrogen isotope deposition, trapping and permeation in fusion-relevant materials.

Europe/Rome 2021-12-06 07:00:00 2021-12-10 21:00:00 Joint ICTP-IAEA Workshop on Medical Physics Aspects of Stereotactic Radiotherapy Techniques | (smr 3566) There is an increasing number of requests from Member States for assistance in the introduction of stereotactic radiotherapy and radiosurgery for intra-and extra-cranial targets. This workshop will assist clinical medical physicists to understand the complexities of this mode of radiotherapy. Modern radiotherapy has substantially increased the use of various forms of Stereotactic Radiotherapy (SRT), including Stereotactic Body Radiotherapy (SBRT) and Stereotactic Radiosurgery (SRS). For these techniques a high radiation dose is delivered in a reduced number of fractions. These treatments are not only performed with specialized, dedicated machines, but also with conventional, non-dedicated linear accelerators equipped with high resolution multi-leaf collimators.   In radiotherapy, accurate dose delivered to the patient is essential. For conventional radiotherapy this has been achieved by internationally adopted codes of practice and standardized radiotherapy techniques. However, many of these techniques are not applicable for stereotactic radiotherapy. This course will instruct the participant on how to ensure the quality of stereotactic radiotherapy to provide patients with safe and effective treatments.   Topics: Justification for using stereotactic radiotherapy (SRT) The physics of SRT with an emphasis on small field dosimetry Simulation and Treatment planning for SRT Treatment delivery of SRT to include the technologies, motion management and image guidance Radiobiology of SRT including fractionation and dose constraints Audits, Clinical trials and quality control Prerequisites: This workshop is for clinically qualified medical physicists (CQMPs as per IAEA publication HHS-25) from United Nations, UNESCO or IAEA Member States who hold a postgraduate-level university degree, preferably in medical physics. The candidate should also have at least 3 years working experience in a hospital and must participate in stereotactic radiotherapy in the clinic. Participants should have an understanding of IAEA TRS-398, "Absorbed dose determination in external beam radiotherapy" and IAEA TRS-483, “Dosimetry of small static fields used in external beam radiotherapy”. The process of selection of participants might include a mandatory written examination. The workshop will be beneficial to clinically qualified medical physicists working in radiotherapy and employing treatment modalities using small fields such as SRT, SBRT and SRS.
