  • The authors have designed and built a modified Positron Emission Tomography (PET) imaging system for monitoring the dose delivered by proton and {gamma}-ray radiotherapy beams. By measuring the amount and ratio of the beam-induced positron-emitting activity, the dose distribution and tissue composition may be determined. The system utilizes fast LeCroy ECLine electronics and a VME multinode transputer based frontend. Utilizing a transputer based filter, positron annihilation events containing timing, energy, and position information will be filtered in real-time at event rates of up to 40 kHz. This will result in only valid events being transmitted back to the host formore » further analysis and display, reducing both storage media requirements and image reconstruction time. At these rates proton radiotherapy beams may be monitored between beam pulses for on-line range verification. It will also be possible to perform bloodflow studies on tumors using the activity induced by a {gamma}-ray radiotherapy beam. Future electronic developments will allow event rates up to roughly 80 kHz. For both treatment modalities, determination of the composition of tumors will directly affect treatment planning through compensation for oxygen enhancement effects to the dose.« less
  • In the AC/DC parallel system, AC power system is separated into two areas by the parallel AC line trip. As a result, it is necessary to recover from asynchronous operation. A method to close tripped AC line, ''Fast synchronous-reclosing method'', is proposed here. This paper consists of two parts: (1) Calculation of the frequency difference limit between the two areas. Energy function is formulated on the condition that fast synchronous-reclosing can be completed satisfactorily. (2) Confirmation of the performance of the fast synchronousreclosing method in the AC/DC parallel line and frequency control before synchronous-reclosing and damping control of the powermore » swing after reclosing, which were studied using an AC/DC simulator.« less
