All-Permanent-Magnet 14.5-GHz ECR Ion Source

该提案要求为原子和分子碰撞实验提供一种特殊类型的离子源，这些实验与中子星碰撞的物理学特别相关。该仪器是一种最先进的14.5 GHz电子回旋共振离子源(ECRIS)，它可以从蒸发的样品材料中高效地产生(金属)多电荷原子离子和分子离子。这一ECRIS将提供比吉森原子和分子物理小组目前可用的离子束强度高得多的离子束强度，从而极大地增强该小组在吉森的实验装置和外部大型研究设施的研究能力，这些设施包括由汉堡的DESY操作的同步辐射源Petra III和由GSI在Darmstadt操作的重离子存储环CRYRING。ECRIS将只包含永久磁铁，因此它不需要像较大的ECRIS那样操作磁铁线圈的电源。因此，所要求的仪器的功耗将相对适中，从而允许大学实验室的可持续运行。ECRIS及其技术外围设备(如射频(RF)、气体入口和水冷却系统)的高度集成设计将便于将其运送到上述研究地点，在那里该仪器将能够对带电量子物质与X射线和粒子束的相互作用进行世界独一无二的实验。

The proposal asks for a special type of ion source for atomic and molecular collision experiments that are of particular relevance for the physics of neutron-star collisions. The to be acquired instrument is a state-of-the-art all-permanent-magnet 14.5-GHz electron-cyclotron-resonance ion source (ECRIS) which can efficiently produce (metallic) multiply charged atomic ions and molecular ions from evaporable sample material. This ECRIS will deliver much higher ion-beam intensities than what is currently available to the Giessen Atomic- and Molecular Physics Group and, thus, greatly enhance the group's research capabilities at its experimental set-ups in Giessen and at external large-scale research facilities such as the synchrotron radiation source PETRA III operated by DESY in Hamburg and the heavy-ion storage ring CRYRING operated by GSI in Darmstadt. The ECRIS will contain only permanent magnets, such that it does not require the operation of power supplies for magnet coils as larger ECRIS do. Consequently, the power consumption of the asked for instrument will be comparatively modest allowing for a sustainable operation in a university laboratory. The highly integrated design of the ECRIS and its technical periphery such as the radio-frequency (RF), gas inlet, and water-cooling systems will facilitate an easy transport to the above mentioned research locations, where the instrument will enable world-unique experiments on the interaction of charged quantum matter with x-rays and particle beams.
