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.

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物理学特别相关。待采购的仪器是最先进的全永磁 14.5 GHz 电子回旋共振离子源 (ECRIS)，它可以从可蒸发样品材料中高效产生（金属）多电荷原子离子和分子离子。该 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，从而大大增强该小组在吉森实验装置和外部大型研究设施的研究能力例如汉堡DESY运行的同步辐射源PETRA III和达姆施塔特GSI运行的重离子存储环CRYRING。 ECRIS 将仅包含永磁体，因此它不需要像大型 ECRIS 那样为电磁线圈供电。因此，所需仪器的功耗相对较小，可以在大学实验室中可持续运行。 ECRIS 及其技术外围设备（例如射频 (RF)、进气口和水冷系统）的高度集成设计将有助于轻松运输到上述研究地点，在那里该仪器将实现世界独特的实验关于带电量子物质与 X 射线和粒子束的相互作用。
