GPT results  for the sphere long anode 9cm gap at -300 kV. This was produced using Yan's GTS parameters. Impact of GBacc on emittance. 
* [[Media:GTS_GPT_3.pptx]]

GPT results  for the sphere long anode 9cm gap at -300 kV. This was produced using Yan's GTS parameters. Impact of field map interpolation step-size on emittance. 
* [[Media:GTS_GPT_2.pptx]]

GPT results  for the sphere long anode 9cm gap at -200 kV. This was produced using Yan's GTS parameters. We are trying to find out why is the measurements and simulated emittance so different.
