T10 - KL target in K12

Inside this 'chateau' the KL target finds a place. The target contains two identical target heads, each consisting of 4 Beryllium rods, 10 cm long each and 2 mm in diameter. The primary proton beam (intensity approximately 1.5 1012 protons per SPS cycle) impinges on this target and produces the neutral 'KL' beam at a nominal production angle of 2.4 milliradians.
