ABSTRACT High temperature is of paramount importance in high pressure science. One of the leading tools in this respect is the resistively heated diamond anvil cell (DAC), where the heat is provided by small heaters, positioned close to the diamond/gasket/sample region (internally heated DAC, IHDAC) or by wrapping the DAC body into bigger heaters (externally heated DAC, EHDAC). Although IHDACs can reach sample temperatures higher than 1000 K, they are difficult to handle and the heater/diamond/gasket/sample region may be affected by strong thermal gradients potentially hindering accurate temperature measurements. Here we present a novel EHDAC, which overcomes these issues by uniquely joining: (i) high mechanical precision for multi-Mbar, (ii) high temperature alloys for operating to 1000 K, (iii) membrane or screw driven, easily switchable between each other, (iv) operation into a vacuum chamber, (v) uniform temperature, (vi) facile handling, and (vii) possibility to add internal heaters for achieving even higher temperatures.

电阻加热、高压、隔膜和螺杆驱动的金刚石砧座

摘要高温在高压科学中至关重要。在这方面的领先工具之一是电阻加热金刚石砧座 (DAC)，其中的热量由靠近金刚石/垫圈/样品区域（内部加热 DAC，IHDAC）或包裹 DAC 的小加热器提供身体变成更大的加热器（外部加热 DAC，EHDAC）。尽管 IHDAC 可以达到高于 1000 K 的样品温度，但它们难以处理，而且加热器/金刚石/垫圈/样品区域可能会受到强热梯度的影响，这可能会阻碍准确的温度测量。在这里，我们提出了一种新型 EHDAC，它通过独特的连接克服了这些问题：(i) 多 Mbar 的高机械精度，(ii) 可在 1000 K 下运行的高温合金，(iii) 膜或螺杆驱动，
