| TUPMB026 | Magnet System for a Compact Microtron | permanent-magnet, vacuum, electron, operation | 1164 |

Funding: Funded by DOE SBIR grant DE-SC0013795 A compact microtron can be an effective gamma source that can be transported to locations outside the laboratory. As part of a Phase I project we have studied a portable microtron that can accelerate electrons with energies of 6 MeV and above as a source for gamma and neutron production. The mass of the magnet is a significant contribution to the overall mass of the system. This paper will discuss conceptual designs for both permanent magnet and electromagnet systems. The choice of mictrotron RF frequency range is determined by the application requirements. The RF frequency influences the size of the microtron magnet and consequently its weight. We have looked at how the design would vary with the different frequency configurations. |

| TUPOY050 | Microtron-based Intense Neutron Source | cavity, neutron, cathode, electron | 2014 |
|

Funding: Funded by DOE SBIR grant DE-SC0013795 An L-Band 7.7-9.8 MeV CW relatively inexpensive microtron with a warm accelerating cavity for multi-purpose applications in nuclear medicine and radiation industry is proposed. The microtron with a photo-neutron converter is intended to serve as an intense source of photo-neutrons with yield up to 4·1012 n/s for nuclear medicine or/and producing of short lived isotopes, as a source of gamma-radiation with dose rates up to 130 kR/min·m with a heavy bremsstrahlung target, and as a source of the electron beam with total energy of 9.8 MeV at the average current up to 4.4 mA for various radiation treatments. |

| THPMR052 | Compact, Microtron-Based Gamma Source | cathode, electron, injection, cavity | 3522 |
|
|||
|
Funding: This work was supported U.S. DOE SBIR Grant DE-SC0013795. The conceptual design of a prototype S-band pulsed, 9.5 MeV compact microtron with type-II injection is described. Estimates of parameters such as beam current and cathode lifetime, and comparisons with X-band and C-band parameters are presented. The electron beam can be extracted at various energies up to 9.5 MeV. Estimated yields of gammas produced at 6.5 MeV operation and estimated yields of gammas and neutrons produced at 9.5 MeV are presented. |

| THPOY026 | Recent Challenges for the 1.5 GeV MAMI-C Accelerator at JGU Mainz | electron, polarization, operation, experiment | 4149 |
|
|||
|
Funding: Work supported by DFG (CRC 1044) and the German federal state of Rhineland-Palatinate The MAMI-C accelerator is a 1.5 GeV microtron cascade for up to 100 μA polarised electrons operating CW at Mainz University. Recent experiments required spin manipulations and beam energies not routinely supported by the accelerator. In particular, this required a spin orientation vertical to the accelerator plane and operation at beam energies which could not be achieved by the so far established methods. This paper describes the challenges to provide and to characterise the unusual modes of operation. |
