BL02B2 Multiple micro-strip detector system
Inquiry number
INS-0000001576
The diffractometer with a multi modular system constructed by six MYTHEN detector is installed at the BL02B2 experimental hutch (Table 1 & Fig. 1). The time resolution is limited to 10 msec. The multi modular system usually takes powder diffraction data at different two 2θ positions because of interval between every detectors (two-step mode, Fig.2: left). In the case of observation of non-ambient experiment, it is useful to fix 2θ position of the multi modular system (single-step mode, Fig.2: right).
The sample temperature can be controlled in a wide range of temperature (20 ∼ 1073 K). The high and low temperature nitrogen gas flow systems are installed for high-temperature (300 ∼ 1073 K) and low-temperature (90 ∼ 500 K) experiments (Fig.3). It is possible to carry out the automated data collection in dependence of temperature controlled by LabVIEWTM software. Under 90 K, temperature must be controlled by a helium gas flow temperature device.
By taking advantage of third-generation high-energy synchrotron radiation, the multi modular system enables one a rapid and easy collection of high angular resolution powder data even for heavy materials. As a result, the beamline has flexibility for many levels of structural studies, for example, from measuring just lattice constants to obtaining accurate electron densities under extreme conditions.
