Measurement of emission spectrum for gaseous argon electroluminescence in visible light region from 300 to 600 nm
Kazutaka Aoyama, Masato Kimura, Hiroyuki Morohoshi +3
A double-phase Ar detector can efficiently identify particles and reconstruct their positions. However, the properties of electroluminescence (EL) for secondary light emission in t…
Development of a high-light-yield liquid argon detector using tetraphenyl butadiene and silicon photomultiplier array
Kazutaka Aoyama, Masashi Tanaka, Masato Kimura +1
To increase the light yield of a liquid Ar (LAr) detector, we optimized the evaporation technique of tetraphenyl butadiene (TPB) on the detector surface and tested the operability…
Measurement of the scintillation efficiency for nuclear recoils in liquid argon under electric fields up to 3 kV/cm
M. Kimura, M. Tanaka, T. Washimi +1
We present a measurement of scintillation efficiency for a few tens of keV nuclear recoils (NR) with a liquid argon time projection chamber under electric fields ranging from t…
Scintillation and Ionization Ratio of Liquid Argon for Electronic and Nuclear Recoils at Drift-Fields up to 3 kV/cm
T. Washimi, M. Kimura, M. Tanaka +1
A two-phase argon detector has high discrimination power between electron recoil and nuclear recoil events based on the pulse shape discrimination and the ionization/scintillation…
