Liquid Pressure Cell 11PL50AO2

This 500 MPa (5 kbar) cell was designed within the framwork of NMI3-II. The prototype is essentially made from hardened CuBe alloy and Sapphire windows. It is optimised for SANS and features a very low background and 84% transmission at 6Å. The sample thickness varies between 0.5 and 2 mm and the temperature is controlled with a thermostatic bath (±10 mK stability). The prototype cell was tested successfully on D11 in June and July 2015 and several versions are being manufactured:

• 50 MPa for Spin-Echo providing Ø30 mm incident beam access (see cell 22PL05AO4)
• 300 MPa for SANS providing Ø10 mm incident beam access (2 copies, see cell 21PL30AO2)
• 500 MPa for SANS (2 copies)
