3.4 Installing the Cryostat
3.4.1 Mounting the Cryostat to the Optical Table
The cryostat can be mounted at either 45° or 90° to the hole pattern in an imperial or metric optical
table. When aligning the system, make sure you can still reach and access the sample chamber.
1. Adjust the cryostat so the mounting holes around the sample chamber are directly aligned with
holes in the optical table.
The baseplate contains four additional mounting locations, two on either side of the black vertical
cryocooler cylinder, and two at the back of the unit. These locations each have a slotted disk for fine
adjustment.
2. Turn the slotted disks at each remaining baseplate location until a table hole is aligned with the
slot.
3. Starting at the front of the sample chamber, insert a short hex screw in each mounting location.
Start by loosely starting each screw, turning just enough to hold the screw in place. Minor
positioning adjustment may still be required.
4. After placing a screw at each location, tighten all screws securely, moving front to back.
On some models, the operational cable may be shipped disconnected:
5. Locate the MDR26 cable coming out of the front of the cryostat tower (next to the black vertical
cryocooler cylinder).
6. Connect the cable to the lower MDR26 connector on the base side panel of the sample chamber
at the location labeled: OPERATIONAL
3.4.2 Removing the Shipping Supports
Once the cryostat is secured to the table, the shipping supports can be removed. These should be
removed for optimal performance.
1. Locate the red C-spacers on either side of the connection point between the sample chamber
and cryocooler (two total). Unscrew the M3 screws.
2. Remove the red caps then pull out the red tab.
