Division Spotlight
Young Members Group
The Young Members Group works to encourage and enable all young professional members to be actively involved in the efforts and endeavors of the Society at all levels (Professional Divisions, ANS Governance, Local Sections, etc.) as they transition from the role of a student to the role of a professional. It sponsors non-technical workshops and meetings that provide professional development and networking opportunities for young professionals, collaborates with other Divisions and Groups in developing technical and non-technical content for topical and national meetings, encourages its members to participate in the activities of the Groups and Divisions that are closely related to their professional interests as well as in their local sections, introduces young members to the rules and governance structure of the Society, and nominates young professionals for awards and leadership opportunities available to members.

Commercial nuclear innovation "new space" age
In early 2006, a start-up company launched a small rocket from a tiny island in the Pacific. It exploded, showering the island with debris. A year later, a second launch attempt sent a rocket to space but failed to make orbit, burning up in the atmosphere. Another year brought a third attempt—and a third failure. The following month, in September 2008, the company used the last of its funds to launch a fourth rocket. It reached orbit, making history as the first privately funded liquid-fueled rocket to do so.

Photon external radiotherapy of cancer takes advantage of the physical interaction of the photon and the secondary electron with biological tissue to kill cancer cells. The current linac is important equipment for producing an X-ray. The Monte Carlo method has been demonstrated to be the most accurate method for radiotherapy issues such as dose calculation and plan verification. However, its application in the clinic requires detailed information on the beam characteristics. A large quantity of the consumptive time for multiple simulation phases, such as linac treatment head simulation, beam trimmer module simulation, and patient/phantom simulation, and storage for the phase-space file (PSF), which records the information of the transported particle, are two knotty issues also. Therefore, a set of simple and convenient multiple source models (MSMs) including five subsources for regular fields from 3 × 3 cm to 30 × 30 cm was built, which is based on a VARIAN 2300C 6 MV-X beam simulated by the Monte Carlo code BEAMnrc and produced by BEAMnrc's beam characteristics analysis utility BEAMDP (BEAM Data Processor). This MSM reduced the three simulation phases to one to effectively decrease the consumptive time. The storage issue about the PSF was also solved for MSM's small volume. The dose distribution of the five-source model in a homogeneous phantom was compared with that of the full linac simulation and measurement data to verify reliability. The characteristics of the subsources were analyzed to present their feature. This work provided the base for implementing the Monte Carlo algorithm into the Accurate Radiotherapy System.
