abstract = {We present the progress in sample environment at the Julich
Centre for Neutron Science (JCNS) at MLZ. During the last
several years, JCNS Sample Environmental group made a big
progress in updating and maintenance of the old cryogenic
equipment and introducing the new ones. In addition to the
tradition Orange-type wet cryostats, several cryogen-free
closed cycle cryostats are in use. Recently new actively
shielded asymmetric vertical field split-coil
superconducting magnet with maximal field of 8T has been
procured and implemented on the beam line of POLI
instrument. It provides a large angular acceptance for the
scattering beam of 300° in the horizontal and 30°
(-5°/+25°) in the vertical plane respectively. Which
permit both a right- and left-handed scattering geometry.
This magnet allows making measurements in the temperature
range 1.4-800K [1]. To extend this temperature interval an
additional 3He-4He dilution insert was added. During
preliminary tests of Kelvinox JT we reached 16mK in the
absence of the neutron beam. An additional vacuum can allow
using it also with the 12T magnet at PANDA instrument. In
future we plan use this and similar Kelvinox JT inserts at
other wet and dry cryostats, as well at the other magnets.
The main advantage of such dilution insert is that due to
the Joule-Thompson stage it is possible to run it directly
from a 4K environment.},
