  * Two possible designs for the magnet base
   * LIGO style one: [[https://www.dropbox.com/s/h47gump6ygi16gg/Small-Magnet-Assy-LIGO-Style.png?dl=0|image]]
    * A dumbbell shaped aluminum stand-off
    * Smaller footprint -> smaller thermal noise
    * Relatively soft (14kHz internal resonance)
    * Easy to be bent
   * VIRGO style one: [[https://www.dropbox.com/s/imzpz3pwt0dlg5s/Small-Magnet-Assy-VIRGO-Style.png?dl=0|image]]
    * Embedding a magnet in a aluminum cylinder
    * Has a larger footprint -> larger thermal noise.
    * Rigid structure. Internal mode frequency is about 94kHz.
  * After some discussion, we will employ the VIRGO like design.
   * We probably do not need a chamfer.
