Cold three axes spectrometer (with optional focussing guides and polarization analysis)
MIRA is a cold three axes spectrometer with wavelengths 3.5 Å < λ < 6 Å (1.2 < k < 1.6). Energy transfers from – 6 meV < ∆E < 3 meV can be reached.
The instrument’s setup is modular and allows for various different cold neutron experiments such as diffraction, spectroscopy or reflectometry. A variety of different setup options can be combined allowing for a fast and flexible realization of neutron experiments using the options available:
Polarised neutrons are optional for all experimental setups at MIRA. Using the finger detector, the instrument has a very low background of less than 0.1 cps. MIRA can reach a q-range up to 2.5 Å-1 with a q-resolution of 0.01 Å-1.
Vertical and horizontal B-fields up to 2.2 T and vertical B-fields up to 12 T are available. Temperatures from 50 mK to 1500 K can be applied using the standard sample environment at MLZ.
