Floating planar movement hovering mechanism

本发明涉及一种气浮装置，具体的说是一种气浮平面运动的悬停机构，用于模拟低摩擦条件下设备在气浮平台系统上的悬浮定位装置。所述悬停机构安装在可悬浮于气浮平台上的设备主机架上，悬停机构包括直线驱动机构、两套拉杆组件及两个摩擦头，其中两套拉杆组件分别铰接于直线驱动机构的两端，两个摩擦头分别安装在两套拉杆组件上，用于与气浮平台摩擦接触，直线驱动机构通过伸缩运动带动两侧拉杆组件运动，使悬停机构的高度改变，从而改变摩擦头与气浮平台之间的摩擦力。本发明对低摩擦环境仪器设备在实验和测量过程中的快速自主定位，不会影响原有气浮状态，并且在定位悬浮过程中不会对设备产生附加扰动力，也不会改变其原有姿态。</p

JUNO Sensitivity on Proton Decay p→νˉK+p\to \bar\nu K^+ Searches

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in $p\to \bar\nu K^+$ mode with JUNO is investigated.The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar\nu K^+$ is 36.9% with a background level of 0.2 events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is $9.6 \times 10^{33}$ years, competitive with the current best limits on the proton lifetime in this channel

JUNO sensitivity on proton decay p → ν K + searches*

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this study, the potential of searching for proton decay in the $p\to \bar{\nu} K^+$ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits suppression of the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via $p\to \bar{\nu} K^+$ is 36.9% ± 4.9% with a background level of $0.2\pm 0.05({\rm syst})\pm$$0.2({\rm stat})$ events after 10 years of data collection. The estimated sensitivity based on 200 kton-years of exposure is $9.6 \times 10^{33}$ years, which is competitive with the current best limits on the proton lifetime in this channel and complements the use of different detection technologies
