Mounting samples in the DCS Orange Cryostat
- The 70 mm Orange cryostat that is normally used at the DCS is 440 mm taller than a standard NCNR 70 mm cryostat. (It is possible to use one of the NCNR's standard cryostats, but to do so requires that special tails be installed so use of a standard length NCNR cryostat is strongly discouraged.)
- The sample stick has a male 5/16-UNC thread, 3/8 inch (9.5 mm) long, to which the sample or sample container is attached. We have a substitute end piece with a male M8 thread, 9.5 mm long.
- We have a 35 mm extension piece that effectively lengthens the cryostat (but not the sample stick). Below you will find two figures. Figure 1 shows the setup without the extension piece. Figure 2 shows the setup with the extension piece. Choose whichever setup is best.
Go to figure 2.
Figure 1. This figure shows the DCS cryostat mounted on the DCS sample stage without the extension piece. With the Huber z stage in its home position the distance from the top flange of the sample well to the beam center line is 1360 mm. The distance from the bottom surface of the sample stick flange to the mounting thread is adjustable from 1295 to 1335 mm. The distance from the top surface of the sample well flange (i.e. the bottom surface of the sample stick flange) to the inside bottom of the cryostat is approximately 1436 mm. Go to figure 2.

Figure 2. This figure shows the DCS cryostat mounted on the DCS sample stage with the extension piece installed. With the Huber z stage in its home position the distance from the top flange of the sample well to the beam center line is 1360 mm. The distance from the bottom surface of the sample stick flange to the mounting thread is adjustable from 1260 to 1300 mm. The distance from the top surface of the sample well flange (from the bottom surface of the sample stick flange) to the inside bottom of the cryostat is approximately 1436 mm (1471 mm). Go to figure 1.
