Sample EnvironmentsTo fullfil the large variety of experimental needs of the users we have given high priority to a maximum versatility of the sample environment. One standard sample set-up is a sample table with x,y,z,w positioning plus (q)-goniometer. On this table various sample environments can be mounted and positioned. For biological and chemical samples we supply a sample changer for cuevettes and solid samples which can be temperature controlled between +5°C and +150°C. We have realised a high pressure cell for liquids up to 5 kbar. Furthermore, the sample table has also be used to position special equipment of the users, like a cryomagnet or a special holder for holographic gratings, rheometers, etc.
A second sample set-up is a vacuum chamber, which is directly connected to the collimator and detector tubes, so that the SANS can be operated at about 5 x 10-2 mbar in a single vacuum system without windows. If better vacuum down to 10-6 mbar or ambient pressure is needed at the sample position, it is possible to insert thin aluminium or sapphire windows at the entrance and exit of the chamber. The chamber is large enough to carry an electromagnet and a sample changer with an optional heated sample position up to 750°C is available.
All standard sample environments are fully remotely controlled by the SINQ instrument control software SICS which enables the user to run automatic scans in his experiments.
