Neutron pressure devices are available in cooperation with the responsible members of LNS.
Before writing a proposal involving pressure, please check the feasibility with both the instrument scientist, and the relevant pressure cell responsible:
- J. White
 : clamp cells - single crystal inelastic and elastic neutron scattering, Paris-Edinburgh Press - powder samples, single crystals in favourable cases.
- D. Sheptiakov: clamp cells - powder neutron diffraction.
Below is a link to a file that provides an overview of the routinely available pressure options at SINQ.
Summary of Pressure Cell Options at SINQ (updated Oct' 2016)
Crucial information concerning each routinely available pressure device is summarised in the table below.
| Name | Contact | Description | Range | Used in | Suitable Beamlines | Dim |
|---|
| P10 | JW | clamp cell for single crystal inelastic or elastic ns | 10-12 kbar at RT, 8-10 kbar at 1.5K | ILL2, ILL5 | FOCUS, TASP, RITA-II, EIGER, ZEBRA | d=7, c=25 |
| P17 | JW | clamp cell for single crystal inelastic or elastic ns | 15-17 kbar at RT, 13-15 kbar at 1.5K | ILL5 | FOCUS, TASP, RITA-II, EIGER, ZEBRA | d=7, c=25 |
| P15 | DS | clamp cell for powder elastic ns | 13-15 kbar at RT, 12-14 kbar at 1.5K | ORI4,ILL5 | HRPT, DMC | d=8, c=25 |
| P10_NMS | JW | non-magnetic clamp cell for single crystal inelastic or elastic ns | 8-10 kbar at RT, 7-8 kbar at 1.5K | ILL2, ILL5, MA09, MA07 | FOCUS, TASP, RITA-II, EIGER, ZEBRA, SANS-I, SANS-II | d=8, c=20 |
| P10_NMP | DS | non-magnetic clamp cell for powder elastic ns | 8-10 kbar at RT, 7-8 kbar at 1.5K | ORI4, MA09, MA07 | HRPT, DMC | d=6, c=25 |
| PE | JW | Paris-Edinburgh press (opposed anvils) | 100 kbar at RT, 50kbar at 20K | The press has a RT mode, or a dedicated CCR for low T mode | HRPT, DMC for powders, RITA-II for single crystal | d=5, c=1.5 |
where:
d: sample space diameter
c: useable sample height
