Goal <strong>of</strong> <strong>Water</strong> <strong>based</strong> liquid scintillator<br />

<strong>Water</strong>-<strong>based</strong> liquid scintillator is different from dissolving<br />

wavelength shifter in water.<br />

Develop a W-LS to be used as energy spectrometers in large-scale<br />

physics experiments<br />

• Replace the hundreds to many tons <strong>of</strong> unloaded or metalloaded<br />

organic liquid scintillators to provide:<br />

• simpler sensitive detection medium<br />

• fewer compatibility problems<br />

• cost savings<br />

• Non-linear photon production plus superior water attenuation<br />

length makes it possible to detect physics below Cherenkov<br />

threshold<br />

• PDK + channel becomes accessible<br />
