While waiting for the secondary beam developed for e11024, I took some pictures for the whole system around the target. The first one was taken with a fisheye lense, magnifying the GRETINA.
The second one was taken with a “super-wide-angle lens” (10@10-20 mm). The S800 spectrograph, the GRETINA electronics (the black “house” on the right), the GRETINA crane (the blue one on the left) were also included.
The CD2 (deuterated polyethylene) target used in e11024. See Y. Maeda et al., NIM A490 (2002) 518-521 for details.
GRETINA has been reconfigured: all the quads have been mounted on 90-degree holes.
