Status report towards implementation of a Compton polarimeter at BEPCII
Mengyu Su, Zhe Duan, Jie Gao +26
Precision beam polarization measurements based on Compton polarimeters are essential for the physics program of future high-energy colliders. In order to prepare for these and to e…
Radiation Campaign of HPK Prototype LGAD sensors for the High-Granularity Timing Detector (HGTD)
X. Shi, M. K. Ayoub, J. Barreiro Guimarães da Costa +74
We report on the results of a radiation campaign with neutrons and protons of Low Gain Avalanche Detectors (LGAD) produced by Hamamatsu (HPK) as prototypes for the High-Granularity…
Offset Simultaneous Conjugate Atom Interferometers
Weicheng Zhong, Richard H. Parker, Zachary Pagel +2
Correlating the signals from simultaneous atom interferometers has enabled some of the most precise determinations of fundamental constants. Here, we show that multiple interferome…
Measurement of the fine-structure constant as a test of the Standard Model
Richard H. Parker, Chenghui Yu, Weicheng Zhong +2
Measurements of the fine-structure constant alpha require methods from across subfields and are thus powerful tests of the consistency of theory and experiment in physics. Using th…
Limits on Lorentz violation in gravity from worldwide superconducting gravimeters
Cheng-Gang Shao, Ya-Fen Chen, Rong Sun +5
We investigated Lorentz violation through anisotropy of gravity using a worldwide array of 12 superconducting gravimeters. The Lorentz-violating signal is extracted from the differ…
Laser frequency stabilization by combining modulation transfer and frequency modulation spectroscopy
Fei Zi, Xuejian Wu, Weicheng Zhong +5
We present a hybrid laser frequency stabilization method combining modulation transfer spectroscopy (MTS) and frequency modulation spectroscopy (FMS) for the cesium D2 transition.…
Controlling the Multiport Nature of Bragg Diffraction in Atom Interferometry
Richard H Parker, Chenghui Yu, Brian Estey +3
Bragg diffraction has been used in atom interferometers because it allows signal enhancement through multiphoton momentum transfer and suppression of systematics by not changing th…
Feasibility study of online tuning of the luminosity in a circular collider with the robust conjugate direction search method
Hong-Fei Ji, Yi Jiao, Sheng Wang +4
The robust conjugate direction search (RCDS) method has high tolerance to noise in beam experiments. It has been demonstrated that this method can be used to optimize the machine p…
High-resolution atom interferometers with suppressed diffraction phases
Brian Estey, Chenghui Yu, Holger Müller +2
We experimentally and theoretically study the diffraction phase of large-momentum transfer beam splitters in atom interferometers based on Bragg diffraction. We null the diffractio…
