| WEOCB1 | HTS Magnets for Accelerator Applications | 2543 |
|
||
| We have developed HTS magnets using the first generation wires for 15 years. HTS materials have larger temperature margin than LTS materials. Magnets can be operated around 20 K or higher temperature and can be conduction-cooled by cryocoolers. The cooling structure becomes simpler and the cooling power of a cooler is high. We expect to excite HTS magnets by AC or pulsed currents without quenching. After successful performance tests of prototype magnets, we fabricated two magnets for practical use, an air-core cylindrical magnet and a super-ferric dipole magnet. The former one is used to polarize ultra-cold neutrons and the latter is a switching dipole magnet to deliver accelerated beams to two target stations by time sharing. Their design and operational performance are presented | ||

| THPVA096 | Development of 11C+ Ion Source for Reacceleration With HIMAC for Real-Time Observation of Dose Distribution | 4686 |
|
||
|
In order to improve the precision of dose distribution in a patient's body in the case of carbon therapy, realtime measurement of the dose distribution with the use of the so called OPEN PET is desirable. For realization of such a treatment, usage of isotope separator online scheme based on target fragment might be inevitable to keep the needed S/N ratio. From the above requirement, we have been developing 1+ ion source of positron emitting 11C+ ions*, which will be charge breeded before injection into the injector LINAC of the HIMAC. 11C+ ion is to be produced by a high intensity proton beam from a cyclotron. In the real process, a small cyclotron like HM20 might provide the proton beam, but at the development stage, we are planning investigation utilizing proton beam from the AVF cyclotron existing at NIRS with K-number of 110. In the present paper, the total scheme of radioactive ion re-acceleration will be described together with the recent ion source development.
