InstrumentIBARAKI Materials Design Diffractometer (iMATERIA)
Overview of instrumentHigh-efficiency, general-purpose neutron diffractometer for the analysis of crystal structure of powder samples over a wide d-range (Q-range).
BeamlineBL20
ModeratorPoisoned decoupled hydrogen moderator
Range of d-spacing0.181 ~ 2.6 Å (SF mode), 5.09 Å (DF mode) (backward detector bank)
0.255 ~ 3.6 Å (SF mode), 7.2 Å (DF mode) (90-degree detector bank)
0.25 ~ 20 Å (SF mode), 40 Å (DF mode) (low-angle detector bank)
12.5 ~ 450 Å (SF mode), 900 Å (DF mode) (small-angle detector bank)
Resolution (Δd/d)0.16 % (@ backward detector bank)
0.5 % (@ 90 degree detector bank)(SF and DF mode)
Estimated measurement time (@ 200 kW, 25 Hz operation )~15 minutes (SF mode), 30 minutes (DF mode) for Si
~20 minutes (SF mode), 40 minutes (DF mode) for LiCoO2
Sample size and/or volumeApproximately 1.4 cc
(φ6mm x 50 mm high. Samples with a height of 20 mm are exposed to the neutron beam. Measurement will take longer for samples with a smaller volume.)
Auxiliary equipment and sample environmentSample changer (room temperature at atmospheric and low pressures )
High temperature furnace (900°C)
High temperature gas controlled furnace (1000°C)
Closed cycle refrigerator (~10K−RT,RT-400°C)
Sample changer for Small angle measurement
Refrigerator with sample changer (10K-RT, RT-800K, 10 samples) is under commission.
