ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Aerospace Nuclear Science & Technology
Organized to promote the advancement of knowledge in the use of nuclear science and technologies in the aerospace application. Specialized nuclear-based technologies and applications are needed to advance the state-of-the-art in aerospace design, engineering and operations to explore planetary bodies in our solar system and beyond, plus enhance the safety of air travel, especially high speed air travel. Areas of interest will include but are not limited to the creation of nuclear-based power and propulsion systems, multifunctional materials to protect humans and electronic components from atmospheric, space, and nuclear power system radiation, human factor strategies for the safety and reliable operation of nuclear power and propulsion plants by non-specialized personnel and more.

ANS webinar to focus on low-dose radiation risk
Join ANS on Thursday, January 21, at noon (ET) for a Q&A with an expert panel as they discuss how to communicate about the risk of low-dose radiation. “Talking About Low-dose Radiation Risk” is a free members-only event that serves as a follow-up to the “Risky Business” President’s Session that took place during the ANS Virtual Winter Meeting last November. The session will take a deeper dive into the many questions generated from the thought-provoking discussion.
Register now to attend the webinar.

A thrust imparted by a permanent-magnets helicon plasma thruster is directly measured by using a pendulum thrust balance. The source consists of a 6.5-cm-inner diameter glass tube and a magnetic nozzle provided by arrays of permanent magnets. The configuration is designed so as to have maximum field strength of about 100 Gauss near the open end of the source. The flow rate of argon propellant is chosen as 25 sccm and a plasma is produced by 13.56 MHz helicon and/or inductively coupled discharges. The main plasma is guided by the magnetic nozzle and flows out from the source. It is observed that the whole structure of the source attached to the pendulum balance moves only during the plasma production, and its displacement is measured by a laser displacement sensor. The obtained maximum thrust is presently 7.5 mN for 2 kW rf power.
