| TUPVA077 | The Phase Slip Factor of the Electrostatic Cryogenic Storage Ring CSR | 2255 |
|
||
| For the determination of the momentum spread of an ion beam from the measurable revolution frequency distribution the knowledge of the phase slip factor of the storage ring is necessary. At various working points of the cryogenic storage ring CSR installed at the MPI for Nuclear Physics in Heidelberg the slip factor was simulated and compared with measurements. The predicted functional relationship of the slip factor and the horizontal tune depends on the different islands of stability, which has been experimentally verified. This behavior of the slip factor is in clear contrast to magnetic storage rings. In the paper we compare the results of the simulations with the measurements | ||

| 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.
