Examples of sample holders with different mechanisms for holding samples in place. (a) Gravity: bars for multiple samples. The typical sample shown on the left is shorter than the bar width, such that spilled beam is absorbed by the aluminium. Photograph courtesy of Ruipeng Li (BNL). (b) Vacuum: cylindrical support for one sample with a 3 mm hole connected to a vacuum pump. Photograph by Eduardo Solano (ALBA). (c) van der Waals forces: holder for up to five samples which are held in place by silicone grease with a sample of typical size (30 mm × 30 mm). Photograph by Brian R. Pauw (BAM).
