摘要

阿基米德实验是一个致力于测量零点能量重量的实验，通过称量由层状II型超导体组成的刚性卡西米尔空腔级联，当这些空腔的反射率被调制时，从而调节了内部的能量。本文介绍了实验的工作原理，并给出了现有样机的结果，结果表明，在大约50 mHz到两个150 mHz的频率范围内，扭矩灵敏度约为10−11 Nm/sqrtHz。此外，还讨论了达到期望的最终灵敏度所需的主要升级。

Archimedes experiment: weighing the vacuum

Archimedes is an experiment devoted to measure the weight of zero point energy by weighing a cascade of rigid Casimir cavitities costituted by a layered type II superconductor, when the reflec- tivity of the cavities is modulated and thus the energy inside. In this paper the working principle of the experiment is presented and the results of the existing prototype are presented, showing the torque sensitivity of about 10−11 Nm/sqrtHz in the region of frequency from about 50 mHz up two 150 mHz. Moreover the major upgrades needed to reach the desired final sensitivity are discussed.
