Focusing Monochromators:
Take-off-angle: 2ΘM = 38.8oWavelength: 1.177 Å (Ge311 and 2.317 Å (Graphite C002) Resolution: Dd/d > 0.5 % Primary collimation:computer controlled, details Sample Position: Flux: up to 1.02x106 n/cm2/sec (Megapie at 1.35mA) Crystal size: 3-5 mm3, estimate your measurement time (smallest crystals: crystal structure NaOs2O6: 0.8mm3, 5.8mg, magnetic structure CuSeOCl: 0.2x1.8x43, 5mg, 1mB Detectors: - two He3-detectors, area 160 mm x 160 mm - one single He3-tube (secondary collimation: radial for 2D, soller for 1D) Scattering angle for detectors: 2D: 0o< 2Θ <77o, λ=1.18Å: max.sinΘ/λ=0.522Å-1, λ=2.31Å: max.sinΘ/λ=0.267Å-1 1D: 0o< 2Θ <115o: λ=1.18Å: max.sinΘ/λ=0.715Å-1, λ=2.31Å: max.sinΘ/λ=0.364Å-1 Tilt: -10o< 2Θ <40o individually for each detector Scientific Applications:
The thermal neutron single crystal diffractometer TriCS
is designed for investigations of commensurate and
incommensurate crystal and magnetic structures
as well as phase transitions driven by temperature,
magnetic field or pressure. Results/Publications TriCS is operated in two geometrical modes: 4-circle equatorial geometry (γ = 0o) and tilting geometry. Equipment for 4-circle-mode: - cryogenics 15-450 K (APD), 4.5-300K (CCR3) - pressure cell (20 kbar, T > 4.5 K) - photocrystallography (400-800 nm, T > 50 K) - furnace (300K-800K) 100mW/cm2 Equipment in tilting mode: - magnetic field (H 6 Tesla vertical, 2 Tesla horizontal) - cryogenics (T > 80 mK (dilution stick)) - furnaces (<2000K) |
