====== Setup for PHYS142 version of e/m. ======

Setup is pretty much the same as for 122/132.  

  * 500V power supplies and tubes taken from first floor labs.
  * Note that I rigged 6 of the setups so that the rectangular coils can be slid out in front of the tube enough to eliminate the roll off of the B-field near the phosphor screen.
  * Need to set out an iOLab for each station.  No accessories needed, just the device and dongle.
