The SINE2020 work-package on Sample Environment aims to improve the environment surrounding samples both on neutron and muon experiments, thus improving data statistics and opening new fields of science. Thanks to close collaboration fostered by SINE2020, each member’s developments will be useful for the other facilities. A total of 40 WP members (scientists, engineers and technicians) met on January 25-26 in Lund to present and discuss updates on the WP tasks.
Below we list the main topics discussed.
Task 7.1: FLOSS software standards for sample environment
The first task is to develop standards to facilitate the communication between the instrument control work station and the sample environment equipment across facilities. Presentations addressed:
Task 7.2: towards efficient sample environment for neutron research
Task 2 is to work towards an efficient sample environment for neutron research.
7.2.1: Signal to background ratio improvements
One of the approaches is to improve the signal-to-background ratio in the detectors. Presentations addressed:
7.2.2a: Non-magnetic goniometer for dilution refrigerators
The second approach is to improve experiments by providing tools to facilitate them and reduce beam-time losses (7.2.2a and 7.2.2b). Presentations addressed:
7.2.2b: Fast cooling furnace
Task 7.3: next generation pressure cells for neutron and muon research
Task three is to build new generation of pressure cells from new materials and designed from novel geometries to boost the capabilities of neutron scattering and muon spectroscopy.
7.3.1: Improved muon spectroscopy piston cell
The first step is to improve the piston cell for muon instruments. Presentations addressed:
7.3.2.a Anvil pressure cells for μSR
Is it possible to use anvil pressure cells on µSR instruments? Any other pressure cell at ISIS?
7.3.2b: Novel anvils for Paris-Edinburgh cells
We would like to replace the anvils and the pressure-transmitting media by materials transparent to neutrons. One idea is to improve the vertical angular access to samples compressed in Paris-Edinburgh cells. Presentations addressed:
7.3.3: Novel non-magnetic, neutron, clamp cell
Looking at clamp cells, the plan is to investigate whether we can have several layers of different materials to improve the cell’s transparency and decrease the diffuse scattering of the cell. Presentations addressed:
7.3.4: 700 bar H2 container for studying storage equipment
Neutrons are ideally suited for investigating hydrogen storage directly and our aim is to provide equipment matching industry requests. Presentations addressed:
Task 7.4: Complementary in-situ measurements for neutron and muon experiments
In task 4 there are two different projects which aim to make complementary measurements on the beam, one for neutrons and another one for muons.
7.4.1: In-situ muonium studies
For muon research the aim is to build a cavity with a RF field that enables to explore mechanisms in chemistry and chemical physics. Presentations addressed:
7.4.2: In-situ NMR setup
The aim here is to build a compact low-field NMR system sitting on a neutron beam that will allow the simultaneous measurement of diffusion coefficients not accessible with neutrons. Presentations addressed:
