WebApr 9, 2024 · The dual-phase TPC using argon or xenon suits such low energy detection. An obvious advantage of argon is the smaller nucleus mass than xenon. The signal rate on argon is larger than that on xenon with the same target mass when the recoil energy is larger than 0.17 keV \(_\mathrm{nr}\). To estimate a feasible detection threshold, we take … The detector at the heart of LZ is a cylindrical dual-phase xenon time projection chamber (TPC). This is composed of a 7-ton liquid xenon target and a small region of gaseous xenon above. The operational principle is as follows. When a WIMP or background scatter occurs, a small amount of kinetic energy is given to a xenon nucleus (or atomic electron). This causes the xenon atom to ricochet around the area near the site of the scatter, converting its energy into the production of …
WebOct 7, 2024 · An important background to the liquid argon detectors is that they are caused by the diffusion of radioactive isotopes in a scintillator (liquid phase). This radioactive isotope is produced in argon’s surrounding devices, such as circulation pipelines and liquid argon containers. The solid argon as a scintillation material in the detector can inhibit the …
