Temperatures from 5°C to 90°C can be achieved with an accuracy of 0.1°C when used with a NESLAB© circulating bath filled with a 50%/50% mixture of water and ethylene glycol. Temperatures from -25°C to 130°C can be achieved with an accuracy of 0.1°C when used with a Julabo© circulating bath filled with silicon oil. This configuration is currently only available on NG7 SANS, but will be coming soon to NG3. Quartz windows are used before the sample and silicon windows after the sample. Quartz is optically transparent and transmits a laser beam used for the rough alignment of the sample block. More precise alignment is done using a neutron camera behind the block along with the double exposure method (taking two pictures, one with the sample aperture in the beam and another without the sample aperture).
