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 (30 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)
TriCS has been financed by:
