Simultaneous and panchromatic observations of the Fast Radio Burst FRB 20180916B
M. Trudu, M. Pilia, L. Nicastro +47
Aims. Fast Radio Bursts are bright radio transients whose origin has not yet explained. The search for a multi-wavelength counterpart of those events can put a tight constrain on t…
CBETA Design Report, Cornell-BNL ERL Test Accelerator
G. H. Hoffstaetter, D. Trbojevic, C. Mayes +51
This design report describes the construction plans for the world's first multi-pass SRF ERL. It is a 4-pass recirculating linac that recovers the beam's energy by 4 additional, de…
A temperature-mapping system for multi-cell SRF accelerating cavities
M. Ge, G. Hoffstaetter, F. Furuta +6
A Temperature mapping (T-map) system for Superconducting Radio Frequency (SRF) cavities consists of a thermometer array positioned precisely on an exterior cavity wall, capable of…
Pressure effect on superconductivity and magnetism in FeSex
L. Li, Z. R. Yang, M. Ge +5
In this paper, pressure effect on superconductivity and magnetism has been investigated in FeSex (x = 0.80, 0.88). The magnetization curves display anomaly at Ts1 106 K and Ts2 78…
Lattice-Driven Magnetoresistivity and Metal-Insulator Transition in Single-Layered Iridates
M. Ge, T. F. Qi, O. B. Korneta +4
Sr2IrO4 exhibits a novel insulating state driven by spin-orbit interactions. We report two novel phenomena, namely a large magnetoresistivity in Sr2IrO4 that is extremely sensitive…
Giant Magnetoelectric Effect in Antiferromagnetic BaMnO3-δand Its Derivatives
O. B. Korneta, T. F. Qi, M. Ge +4
Hexagonal perovskite 15R-BaMnO2.99 with a ratio of cubic to hexagonal layers of 1/5 in the unit cell is an antiferromagnetic insulator that orders at a Néel temperature TN = 220 K…
Non-stoichiometry effects on the extreme magnetoresistance in Weyl semimetal WTe2
J. X. Gong, J. Yang, M. Ge +9
Non-stoichiometry effect on the extreme magnetoresistance is systematically investigated for the Weyl semimetal WTe2. Magnetoresistance and Hall resistivity are measured for the as…
Einstein Probe discovery of the short period intermediate polar EP J115415.8-501810
Y. Xiao, M. Ge, N. Rea +21
The X-ray transient source EP240309a/EP\,J115415.8501810 was first detected by the Wide-Field X-ray Telescope (WXT) on board Einstein Probe (EP) during the commissioning phase.…
Investigations of surface quality and SRF cavity performance
G. Wu, M. Ge, P. Kneisel +4
Magnetic field enhancement has been studied in the past through replica and cavity cutting. Considerable progress of niobium cavity manufacturing and processing has been made since…
Planar Hall effect in type-II Weyl semimetal WTe2
Y. J. Wang, J. X. Gong, D. D. Liang +4
Adler-Bell-Jackiw chiral anomaly is a representative feature arising from the topological nature in topological semimetal. We report the first experimental observation of giant pla…
Field-dependent surface resistance of a superconducting RF cavity caused by surface impurity
M. Ge, F. Furuta, M. Liepe +1
Q-slope issue, which is caused by the field dependent surface resistance, puzzled people for a long time in SRF fields. In this paper, we related the Q-slope with surface treatment…
Extracting superconducting parameters from surface resistivity by using inside temperatures of SRF cavities
M. Ge, G. Hoffstaetter, H. Padamsee +1
The surface resistance of an RF superconductor depends on the surface temperature, the residual resistance and various superconductor parameters, e.g. the energy gap, and the elect…
