Automounters are intended to help maximize throughput at synchrotron beam lines where heavy shielding and safety interlocks slow manual access to the experiment. A sizable number of crystals can be stored in the hutch, accessed randomly, mounted and dismounted; all without entering the hutch.
MacCHESS has an ALS-style BAM-2 crystal automounter with a 3-axis Cartesian robot. It holds 9 ALS pucks or Uni-Pucks for a total of 144 samples available.
