Figure 4
(a) Photograph of the DPU installed at ID10-COH. (b) Schematic of the DPU setup showing in particular the two sets of slits (installed upstream and downstream). The upstream slit is sometimes used to define the beam, the downstream slit is used as a clean-up slit. (c) Photograph of the DPU as integrated with an (in-vacuum) sample environment. Highlighted are one of the two sets of slits (rs2) as well as the sample environment and gate valve. The gate valve is used to isolate the detector tube while replacing the sample. (d) Schematic illustrating the DPU configuration used for several experiments: the sample environment is connected to the DPU via a flexible connection (KF16 bellow) and to the `detector tube' (typically 4 to 7 m long). For replacing the sample, the gate valve is closed, the sample chamber vented. Once the sample is replaced, the sample chamber is pumped down before the gate valve is opened. |
