GPT, CST, COMSOL
CORRECTION: CST and GPT info for the T-shape, mushroom, small mushroom, sphere small anode 6cm gap, sphere long anode 6cm gap, sphere long anode 9cm gap at -200 kV. This file has the CEBAF parameters. Media:Guns_CST_1_CORRECTED.pptx
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. Media:GTS_GPT_1.pptx
