Abstract
The NAIAD experiment (NaI Advanced Detector) for weakly interacting massive particle (WIMP) dark matter
searches at Boulby mine (UK) is described. The detector consists of an array of encapsulated and unencapsulated
NaI(Tl) crystals with high light yield. Six crystals are collecting data at present. Data accumulated by four of them (10.6
kg year exposure) have been used to set upper limits on the WIMP–nucleon spin-independent and WIMP–proton
spin-dependent cross-sections. Pulse shape analysis has been applied to discriminate between nuclear recoils, as may be
caused by WIMP interactions, and electron recoils due to gamma background. Various calibrations of crystals are
presented.
