Detailed Drawings (A4 size, 300dpi, gif files)
The second focal plane is used when high resolution (P/delta p= 12000) is required with a medium solid angle of 10msr. I the case, the last two elements QE magnify a part of the image produced at the first focal plane.
A neutron TOF facility is also available on the line of A1 and Q2 through D1 along the south wall of the vault. The flight path will reach about 80 m in future. (20 m now available).
