9318671德赫梅尔特这项题为“自由空间静止的单原子粒子4(SEPARIS 4)”的提议是为了继续努力接近在纯电射频陷阱中弹性束缚的单个原子离子在光谱学中的分辨率和精度的基本极限。目标是1/1018的精度。过去实现的最好的“精确度”和1000天稳定性是1013或105。新的“精确度”将意味着,同一实验室中两个不同小组对同一原子线的独立频率测量结果一致好于1018,长期(108秒或1000天)稳定性也同样良好。这将对基础物理学和宇宙学的测量产生许多影响。目前原子钟的精度已经受到毫秒脉冲星极高的时间稳定性和空间任务需要的限制。如果没有精确的原子钟,就不可能观察到其他脉冲星由于引力辐射而造成的质量损失。在国内,全球定位系统关键依赖于精确的原子钟。随着越来越多的测量任务被简化为精确的频率测量,在计量学中似乎有无限的新应用领域。
英文摘要
9318671 Dehmelt This proposal, "Single Atomic Particle at Rest in Free Space 4 (SEPARIS 4)", is for the continuation of efforts to approach the fundamental limits of resolution and accuracy in optical spectroscopy for an individual atomic ion elastically bound in a purely electric rf trap. The aim is an accuracy of; one part in 1018. The best "accuracy" and 1000-day stability realized in the past is 1013 or 105 less. The new "accuracy" would mean that independent frequency measurements on the same atomic line by two different groups in the same laboratory agree to better than 1018 and long term (108 sec or 1000 days) stability is as good. This would have numerous implications for measurements in fundamental physics and cosmology. The precision of current atomic clocks is already being strained by the extraordinarily high timing stability of the millisecond pulsars and the needs of space missions. The mass loss of other pulsars due to gravitational radiation could not have been observed without precise atomic clocks. Closer to home the Global Positioning System relies crucially on precise atomic clocks. There seems to be an unlimited field of new applications in metrology as more and more measuring tasks are reduced to precise frequency measurement.
