Parameter optimization of Josephson parametric amplifiers using a heuristic search algorithm for axion haloscope search
Younggeun Kim, Junu Jeong, SungWoo Youn +5
The cavity haloscope is among the most widely adopted experimental platforms designed to detect dark matter axions with its principle relying on the conversion of axions into micro…
Development of axion haloscopes for high-mass search at CAPP
SungWoo Youn, Junu Jeong, Yannis K. Semertzidis
The axion offers a well-motivated solution to two fundamental questions in modern physics: the strong CP problem and the dark matter mystery. Cavity haloscopes, exploiting resonant…
First prototype of a biaxially textured YBaCuO microwave cavity in a high magnetic field for dark matter axion search
Danho Ahn, Ohjoon Kwon, Woohyun Chung +7
A high-quality factor microwave resonator in the presence of a strong magnetic field could have a wide range of applications, such as axion dark matter searches where the two aspec…
Noise temperature measurements for axion haloscope experiments at IBS/CAPP
S. W. Youn, E. Sala, J. Jeong +2
The axion was first introduced as a consequence of the Peccei-Quinn mechanism to solve the CP problem in strong interactions of particle physics and is a well motivated cold dark m…
Exploiting higher-order resonant modes for axion haloscopes
Jinsu Kim, SungWoo Youn, Junu Jeong +3
The haloscope is one of the most sensitive approaches to the QCD axion physics within the region where the axion is considered to be a dark matter candidate. Current experimental s…
Axion Dark Matter Research with IBS/CAPP
Yannis K. Semertzidis, Jihn E. Kim, SungWoo Youn +34
The axion, a consequence of the PQ mechanism, has been considered as the most elegant solution to the strong-CP problem and a compelling candidate for cold dark matter. The Center…
Maintaining high Q-factor of superconducting YBaCuO microwave cavity in a high magnetic field
Danho Ahn, Ohjoon Kwon, Woohyun Chung +6
A high Q-factor microwave resonator in a high magnetic field could be of great use in a wide range of fields, from accelerator design to axion dark matter search. The natural choic…
Comment on "Tunable Supermode Dielectric Resonators for Axion Dark-Matter Haloscopes"
Jinsu Kim, SungWoo Youn, Junu Jeong +1
We comment on a recently published paper, Phys. Rev. Applied 9, 014028 (2018), which presents frequency-tuning mechanisms for dielectric resonators and demonstrates their potential…
Magnetoresistance in copper at high frequency and high magnetic fields
Saebyeok Ahn, Sung Woo Youn, Jonghee Yoo +8
In halo dark matter axion search experiments, cylindrical microwave cavities are typically employed to detect signals from the axion-photon conversion. To enhance the conversion po…
