High-pressure research is essential for Earth and materials science, solid state physics and chemistry. The Geoinstitut is the leading facility for high-pressure research in Earth sciences in Europe, combining virtually all instruments of modern high-pressure research at one site. Many of the experimental facilities are unique in Europe, some are unique worldwide (e.g. 5000 ton multi anvil press; novel cubic press with six independent anvils; apparatus for the simultaneous measurement of Brillouin spectra and X-ray difffraction patterns on single crystals in diamond anvil cells; new portable laser-heating devices).In 2013 - 2016, more than 40 research groups from Germany and abroad visited Bayerisches Geoinstitut with support from the DFG Core Facility. Most of the visitors came from universities, but also from other research institutes (MPG, Fraunhofer UK). Projects included research topics from Earth and planetary science, material science, and solid-state physics, such as the evolution of planet Mercury, texture development in the lowermost Earth´s mantle, or the annealing of defects in diamonds for applications in color center lasers. The purpose of the present application for extension of Core Facility funding is to continue to make the facilities of Bayerisches Geoinstitut available for external users. Experience in the last three years had shown that in particular, the possibility to carry out a small number of exploratory experiments for free is essential for many groups; this kind of access can only be granted with support from DFG. Moreover, the DFG funding will be used to improve the experimental capability of the available facilities; this will include the extension of the routinely accessible pressure range of multi anvil presses beyond 30 GPa using WC anvils, a technology that would be unique in Europe.Access to external users will be granted in two different modes: (1) Users with approved DFG grants may pay for experiments (2) users without such grants may carry out exploratory studies free of charge. All high-pressure equipment will be made available to external users; all analytical equipment may be used free of charge if it is necessary for the high-pressure experiments. All external users will be supported by staff scientists in their experiments; this includes advice in optimum experimental design and data evaluation. Guest offices will be provided to the visitors and the secretarial staff of the institute will provide support in booking hotel rooms and other logistics. The high-pressure laboratories of Bayerisches Geoinstitut will remain accessible for external users after termination of DFG funding; this will, however, require that users then pay for the full costs of experiments.

高压研究对于地球与材料科学、固体物理和化学都是必不可少的。地球研究所是欧洲地球科学高压研究的领先机构，在一个地点结合了几乎所有现代高压研究仪器。许多实验设备在欧洲是独一无二的，有些在世界上也是独一无二的（例如，5000吨多砧压机；具有六个独立砧的新型立方压机；同时测量金刚石砧细胞中单晶布里温光谱和x射线衍射模式的装置；新的便携式激光加热装置）。2013年至2016年，在DFG核心设施的支持下，来自德国和国外的40多个研究小组访问了Bayerisches geoinstitute。大多数参观者来自大学，但也有来自其他研究机构（MPG, Fraunhofer UK）。项目包括来自地球和行星科学、材料科学和固体物理学的研究课题，如水星的演化、地球最下层地幔的纹理发育，或用于色心激光器的钻石缺陷退火。目前申请延长核心设施经费的目的是继续向外部用户提供巴伐利舍斯地质研究所的设施。过去三年的经验表明，特别是免费进行少量探索性实验的可能性对许多团体至关重要；这种访问只有在阿富汗政府的支持下才能获得。此外，发展中国家基金的资金将用于改善现有设施的实验能力；这将包括使用WC压台将多压台压力机的常规可达压力范围扩展到30 GPa以上，这项技术在欧洲将是独一无二的。对外部用户的访问将以两种不同的模式授予：(1)获得批准的DFG拨款的用户可以支付实验费用；(2)没有此类拨款的用户可以免费进行探索性研究。高压设备全部对外开放；如果高压实验需要，所有分析设备都可以免费使用。所有外部用户的实验将得到工作人员科学家的支持；这包括在最佳实验设计和数据评估方面的建议。客人办公室将提供给来访者，研究所的秘书人员将在预订酒店房间和其他后勤方面提供支持。在终止DFG资助后，Bayerisches地质研究所的高压实验室将继续供外部用户使用；然而，这将要求用户支付实验的全部费用。
