SANS SAMPLE CAN INFO

We provide a variety of sample cans for SANS use. There three types of most often with polarized beam experiments. Please contact one of the scientific contacts below for more information.

The scattering is shown from a multi-position Al sample holder designed to fit into a cryostat and the Titan magnet for (A) Lens configuration and (B) 13 m, 4 m, and 1 m configuration. The scattering has been placed on absolute scale, but scaled to 0.1 cm (the actual Al thickness) rather than the typical 1.0 cm. Blocked beam background (dark noise) has been subtracted, while the scattering from the main beam itself was left in place to give an idea of how much background must be dealt with in a typical experiment. (Note use of a cryostat with Al shield will increase this background level.) A 3/8" mask was used, and the Al transmission was measured at 0.963 and 0.964 for the newer and original sample holders, respectively. Error bars of one standard deviation are included.
