108 Considering different applications (high forces, low forces, pushing or pulling) the assembly follows slightly different paths. Generally, assembling the load frame can be broken down into these steps:
109
110 * Install a base plate on the rotation stage (use spacers, decide which plate to use)
111 * Mount load cell on base plate with desired pin or clamp (depending on push or pull experiments)
112 * Mount sample tube (choose the tube type according to your application)
113 * Mount pusher

345 Depending on your application, sample installation may vary. There are a selection of pushing pins and pulling clamps available at the beamline which will be presented in this section. Nevertheless these pins or clamps may be unsuitable for your sample. In this case a suitable pin or clamp can be manufactured. Please contact the beamline staff well in advance of your beamtime.
