摘要
A new cylindrical low-mass central drift chamber has been constructed for the K+ → π+νν experiment at BNL (E787). The chamber consists of twelve layers of axial wire cells and six layers of thin cathode-strip foils, four of which are supported by differential gas pressure. The momentum resolution (RMS) for muons and pions in the range 150–250 MeV/c is found to be about 0.9%.
