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.

高压研究对于地球和材料科学、固态物理和化学至关重要。地球研究所是欧洲地球科学高压研究的领先设施，几乎将所有现代高压研究仪器集中在一个地点。许多实验设施在欧洲是独一无二的，有些在世界范围内也是独一无二的（例如5000吨多砧压机;具有六个独立砧的新型六面顶压机;用于同时测量金刚石砧单元中单晶上的布里渊谱和X射线衍射图案的装置; 2013年至2016年，来自德国和国外的40多个研究小组在DFG核心设施的支持下访问了巴伐利亚地质研究所。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，材料科学和固态物理学的研究课题，如水星的演化，地球最低地幔的纹理发展，或钻石缺陷的退火，以应用于色心激光器。本申请延长核心基金供资的目的是继续向外部用户提供巴伐利亚地质研究所的设施。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;只有在DFG的支持下才能提供这种机会。此外，DFG的资金将用于提高现有设施的实验能力;这将包括使用WC砧将多砧压力机的常规可达压力范围扩展到30 GPa以上，这是欧洲独一无二的技术。外部用户将以两种不同的模式访问：（1）获得DFG批准的用户可以支付实验费用（2）没有此类赠款的用户可以免费进行探索性研究。所有高压设备都将提供给外部用户;如果高压实验需要，所有分析设备都可以免费使用。所有外部用户将在实验中得到科学家的支持;这包括最佳实验设计和数据评估方面的建议。将为来访者提供客房办公室，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助。巴伐利亚地质研究所的高压实验室将在DFG资助终止后继续向外部用户开放;然而，这将要求用户支付实验的全部费用。
