Abstract: Caesium-137 irradiates electronic paper. An incoming gamma-ray from the Cs-137 interacts with a particle inside a micro-container by generating a recoil electron and/or a hole. Because the recoil electron physically leaves the particle, the particle is charged depending on the dose from the radiation source. And, the charge of the particles change, which results in a movement of the particles within the micro-container. After refreshing the electronic paper, a visible difference in the gray-scale can be seen. Thus, the visible difference in the gray-scale is an effect caused by the irradiation of the electronic paper, showing sensitivity to high energy radiation—thus, non-optimized electronic paper is sensitive to high energy radiation and can be used as a radiation dosimeter. In addition, electronic paper can be used for sensing chemical and bio-chemical agents, as well as detecting high energy radiation.

Abstract translation: 铯-133辐射电子纸。 来自Cs-137的进入的γ射线通过产生反冲电子和/或孔而与微容器内的颗粒相互作用。 因为反冲电子物理地离开颗粒，所以根据辐射源的剂量对颗粒进行充电。 并且，颗粒的电荷改变，这导致微粒在微型容器内的移动。 刷新电子纸后，可以看出灰度的明显差异。 因此，灰度的可见差异是由电子纸的照射引起的影响，显示出对高能量辐射的敏感性，因此，未优化的电子纸对高能辐射敏感，并且可以用作辐射剂量计 。 此外，电子纸可用于感测化学和生物化学试剂，以及检测高能量辐射。

Abstract: Systems and methods are provided to perform efficient, automatic cyclotron initialization, calibration, and beam adjustment. A process is provided that allows the automation of the initialization of a cyclotron after overnight or maintenance imposed shutdown. In one embodiment, five independent cyclotron system states are defined and the transition between one state to another may be automated, e.g., by the control system of the cyclotron. According to these embodiments, it is thereby possible to achieve beam operation after shutdown with minimal manual input. By applying an automatic procedure, all active devices of the cyclotron (e.g., RF system, extraction deflectors, ion source) are respectively ramped to predefined parameters.

Abstract: Systems and methods are provided to perform efficient, automatic adjustment of cyclotron beam currents within a wide range for multiple treatment layers within the same patient and treatment session. In one embodiment, efficient adjustment is achieved by using beam current attenuation by an electrostatic vertical deflector installed in the inner center of the cyclotron. The beam current may, for example, be adjusted by the high voltage applied to the electrostatic vertical deflector. In front of each treatment the attenuation curve of the vertical deflector is recorded. Based on this attenuation curve, the vertical deflector voltage for the needed beam current of each irradiation layer is interpolated. With this procedure the beam current could be automatically adjusted in minimal time over a wide range while maintaining a high level of precision.
