McStas neutron instrument simulations

09:02 Differences between document 1 (June 02) and document 2 (June 16): iso_samp component (Incoherent sample): yheight: 0.004 → 0.04 (10× taller) Added order = 1 parameter (restricts to single scattering) New component added: beamstop_1 (Beamstop, xwidth=0.074, yheight=0.074) at z=3.49 relative to sample — absent in doc 1 Banana_1 (Monitor_nD) options string: theta bins: 221 → 384 theta limits: [5, 140] → [-40, 140] y bins: 136 → 256
