WEIB01 | Chasing Femtoseconds – How Accelerators Can Benefit from Economies of Scale in Other Industries | 1973 |
|
||
Building accelerators we frequently push the limits of what is possible in terms of performance. When trying to solve a very challenging engineering problem, we normally resort to specialization; we narrow our focus. This talk suggests a possible alternative path. Huge benefits and great results can be achieved by combining creative ideas and approaches with ideas and solutions borrowed from the economies of scale like telecommunications. The aim of the talk is to show possibilities for combining ideas, technologies and components from different industries into innovative products. | ||

WEIB02 | Towards Developing Accelerators in Half the Time | 1978 |
|
||
The talk challenges conventional wisdom about how to improve product development processes and broadens the concept of product development cycle time reduction techniques. It provides some original ideas; it discusses approaches to managing product architecture that are well suited for rapid development and how the engineering concepts of system architecture, queuing theory, feedback theory, and information theory can be applied to manage the product development management. | ||

THOAB02 | Metal Nano-particle Synthesis by using Proton Beam | 2871 |
|
||
Funding: This work was conducted as a part of the Proton Engineering Frontier Project supported by the Ministry of Education Science & Technology of Korea Government. Many scientists have studied metal nano-particles for newly known optical, electronic and chemical properties. The unique properties of nano-particles have a tendency to relate the particle size and shape. Electron beam have been used for the nano-particle synthesizing and many results were published. Study of nano-particles synthesize by using proton beam is still in the early stages however study for gold, silver, platinum and cobalt nano-particle was in progress. 100 MeV proton linear accelerator, which is by Proton Engineering Frontier Project, Korea Atomic Energy Research Institute, is scheduled to be completed by 2012. Study of nano-particle synthesize by using proton beam will become active due to the completion of 100 MeV proton accelerator and it can be mass-produced because of the large current beam. Finally, industrial applications could become possible. The mechanism of metal nano-particles synthesizing by proton beam irradiation was not completely known. In this study, we investigated the changes of size and shape for metal nano-particle depending on the condition of proton beam irradiation, and concentration of additives by TEM and UV/Vis spectrophotometer. |

THPS089 | Application of Particle Accelerators to Study High Energy Density Physics in the Laboratory | 3642 |
|
||
High Energy Density (HED) Physics spans over wide areas of basic and applied physics. Strongly bunched high quality intense particle beams are an excellent tool to generate HED matter in the laboratory. Over the past decade, we have carried out extensive theoretical work to design HED physics experiments for the future FAIR facility at Darmstadt. These experiments will be carried out to study the equation-of-state properties of HED matter*, interiors of the Giant planets**, growth of hydrodynamic instabilities in solids and ideal fluids in the linear and the non-linear regimes*** as well as the solid constitutive properties of materials of interest under dynamic conditions.

THPS101 | Present and Perspectives of the Sparc THz Source | 3669 |
|
||
The development of radiation sources in the THz spectral region has become more and more interesting because of the peculiar characteristics of this radiation: it is non ionizing, it penetrates dielectrics, it is highly absorbed by polar liquids, highly reflected by metals and reveals specific "fingerprint" absorption spectra arising from fundamentals physical processes. The THz source at SPARC is an accelerator based source for research investigations (e.g. material science, biology fields). Its measured peak power is of the order of 108 W, very competitive with respect to other present sources. The present status of the source is presented and future perspectives are presented. | ||
THPS102 | Novel Schemes for the Narrow Band Sparc THz Source using a Comb like e-beam | 3672 |

The development of radiation sources in the THz spectral region has become more and more interesting because of the peculiar characteristics of this radiation: it is non ionizing, it penetrates dielectrics, it is highly absorbed by polar liquids, highly reflected by metals and reveals specific "fingerprint" absorption spectra arising from fundamentals physical processes. The THz source at SPARC is an accelerator based source for research investigations (e.g. material science, biology fields). By means of e-beam manipulation technique, a longitudinal modulated beam, the so-called comb beam, can be produced at Sparc. In terms of THz sources, such e-beam distribution allows to produce high intensitiy narrow band THz radiation, whose spectrum strongly depends on the charge distribution inside the e-beam. Different linac schemes are compared. In particular, spectra obtained using the comb-beam compression through velocity bunching including a IV harmonic RF section is showed. | ||
THPS103 | The Proton Engineering Frontier Project: Status and Prospect of Proton Beam Utilization | 3675 |
|
||
Funding: This work has been supported by the Ministry of Education, Science, and Technology, Republic of Korea. A 100-MeV, 20-mA high intensity proton linac is to be constructed in 2012 by the PEFP (Proton Engineering Frontier Project) of the Korea Atomic Energy Research Institute, which was started in 2002 with three main objectives; development of high intensity proton linac, development of proton beam utilization technologies, and industrialization of developed technologies. Proton beams with variable energy and current can be provided to the users from various research and application fields such as nano-, bio-, semiconductor-, space-, radiation-, environment-technologies and medical- and basic sciences, etc. through 10 targets rooms, which are assigned specific application fields to meet various user’s beam requirements. Following a brief introduction to the accelerator development, multiple beamline development and the construction works, we will review the achievements of our user program which have been operated over the past 8 years to cultivate and foster proton beam users and beam utilization technologies in diverse R&D fields. In addition, we will discuss the perspectives of the beam utilization in conjunction with design and construction of user facilities. |

THPS104 | Radio-activation Effect of Target Rooms for PEFP's 20~100 MeV Linear Accelerator | 3678 |
|
||
Funding: This work was conducted as a part of the Proton Engineering Frontier Project supported by the Ministry of Education Science & Technology of Korea Government. PEFP (Proton Engineering Frontier Project) has developed a 20~100 MeV/20 mA proton linear accelerator, proton beam utilization technology and accelerator applications, in order to acquire core technologies which are essential to develop future science and secure the industrial competitiveness. In the experimental hall, 10 target rooms will be constructed for the research of radioisotopes, material, medical, neutron source, etc. In the irradiation experiments using proton beam of more than a few MeV energy, radio-activation of targets and equipments can be essentially caused by the proton induced nuclear reactions. Highly radioactive samples occasionally makesome problems or inconveniences concerning with sample handling and post-treatment because we have to wait for the samples to be cooled down under the safe value for radiation protection. So we estimated proton beam irradiation condition of each target room and used samples including equipments, then we calculated radio-activation of each target room by using Monte Carlo N-particle Transport Code. |
