Wien filter stuff:
Double thickness mounting tab sims.
Wien filter 6: What do we need for the 200 kV Wien filter using the UITF one as a base?
Wien filter 4: What do we need for the 200 kV Wien filter using the UITF one as a base?
Wien filter 3: I measured the vacuum lab's Wien filter and checked what we can scavenge for the 40 kV feedthrough version.
Wien filter 2: Simulation results for the 40 kV feedthrough for Wien filter at UITF.
Wien filter 1: Simulation results for the existing (05/22/2019) Wien filter at UITF.

Ey difference for T-cathode and Small shield (From CST field maps)
GPT, CST, COMSOL
CST particle tracking of T-cathode, Small Shield and Big Shield @-200 kV
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.
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.
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.
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.
THIS FILE HAS BEEN CORRECTED: 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.
Preliminary GPT results for the T-cathode vs Mushroom vs Sphere at -200 kV. This file has the CEBAF parameters. This is the same as the previous entry but shows extra slides with comparisons of the three cathodes wth one metric as requested by Matt.
