For high power proton accelerators like SNS, ESS or the planned neutrino factory (CERN), negative ions are preferred because they offer charge exchange injection into the accumulation rings (non Liouvillian stacking). The low energy beam emittance is a key parameter in order to avoid emittance growth and particle losses in the high-energy sections. Conventional destructive emittance measurement methods like slit-harp systems are restricted for high power ion beams by the interaction of the ion beam with e.g. slit or harp. Therefore a non-destructive emittance measurement has several technical and physical advantages. To study the transport of high perveance beams of negative ions, a Low Energy Beam Transport (LEBT) section is under construction. The study of non destructive emittance measurement devices is one major subject of the test bench. For negative ions -especially H[sup -]-ionsphotodetachment can be applied for a non-destructive emittance measurement instrument (PDEMI). The paper will present the status of that emittance diagnostic and of the test bench.
