Dynamic performance of the beam position monitor support at the SSRF

X. Wang, Y. Cao, H. Du and L. Yin

Synopsis: The dynamic performance of the beam position monitor support at the Shanghai Synchrotron Radiation Facility is studied by finite-element analysis and vibration measurements. The mechanical stability of the support is improved by changing the connections between the support and the ground.

J. S. Smith and S. Desgreniers

Synopsis: A method for positioning diamond anvil cell samples at a centre of rotation is described and evaluated, after which the practice of rocking properly centred polycrystalline samples is examined. These selected techniques are crucial to optimizing the quality of data, and hence the accuracy of structural parameters, obtained from microscopic samples submitted to extreme pressure conditions.
