The Excitations & Polarized Neutron Group at ISIS is seeking an Instrument Scientist to work with the polarized neutron facilities at ISIS, to provide polarized neutron capability on several instruments at ISIS – including LET, WISH, and LARMOR on the ISIS 2nd target station.
Much of this work will be based on the use of 3He neutron spin filters, and will involve the development of; optical pumping techniques; 3He cell materials; magnetic field environments; computer control and interfacing; reduction and analysis software ISIS is equipped with a state-of-the-art 3He filling station capable of providing on-beam 3He neutron spin-filters with > 70% polarization. In addition,the polarized neutron section has developed an in-situ 3He polarizer, and several magnetic holding field devices, including a version of PASTIS for the LET spectrometer. The instrument scientist for polarized neutrons will also be expected to provide experimental support to ISIS users during their diffraction / spectroscopy experiments using a range of experimental techniques for polarization analysis.
In addition to a suite of 28 neutron and muon instruments, ISIS hosts extensive user support facilities, including high pressure /high-magnetic field sample environment equipment, and a large suite of sample preparation, characterization and alignment facilities, (including X-ray diffractometers, PPMS and MPMS systems, sample prep furnaces, X-ray fluorescence and a neutron alignment facility).ISIS scientists pursue wide and active research programs across a diverse range of fields.
List of Duties / Work Programme/ Responsibilities
The duties of the Instrument Scientist for Polarized Neutrons will include:
·To provide scientific and technical support to scientific visitors to ISIS both using, and developingpolarized neutron techniques
·To work as part of a team to develop novel instrumentation, techniques and software
·To conduct an active programme of research at ISIS
·PhD (or equivalent) in physics
·Several years post-doctoralexperience in a research environment (Band E level) – or early stage (recentPhD completion) researchers considered (Band D level)
