The WArP Experiment: A Double-Phase Argon Detector for Dark Matter Searches

Table 1

Relative fast-to-slow signal intensity ratio in LAr for different particles in zero-field conditions [23]. LET increases from electrons to fission fragments, and 𝐼_𝑓/𝐼_𝑠 increases as well.

Ionising particle	𝐼𝑓/𝐼𝑠
Rel. electrons	0.3
𝛼-Particles	1.3
Fission fragments	3.0
