8 of the 10 detectors have been mounted with one hemisphere, and the hemispheres were open without the beam pipe. The GRETINA configuration itself is the same as GRETINA+S800+LENDA, but LENDA is not used in the upcoming experiments. I did some high-dynamic-range (HDR) pictures.
Two shots with a wide-angle lens.
A close shot for 4 of the detectors—reflecting the yellow quadrupole doublets.
