Spiral Scan of Chalice

Monday 26 March 2012 - Filed under Uncategorized

A python program has been created which moves the light source (monochronometer) in a square spiral from the Chalice center via the VMX controller. The Keithley electtometer current is recorded and the x,y position is recorded to a logfile.

A 9 point test scan and current vs position map is shown in figure at spiralScan.
