Modeling Updates

Gabriel and Josh need to learn how to run existing CEBAF GPT deck from Gun to Chopper (130 kV, cathode no-shed?, anode grounded, solenoids, Jay Wiens?)

Gabriel's 200kV upgrade modeling jobs

Incorporate small-shed to CEBAF model, use GPT to compare 130kV vs. 200kV (to compare at CEBAF when installed?)

Optimize HV design for Jay's original 200KV Wien, work w/ Jay to build E/B model and evaluate in GPT, consider optical/operation improvements

Work w/ Alicia to incorporate 200KV Wien models into the CEBAF upgrade deck, for testing layout we want to build

Josh's Ion-bombardment modeling jobs => CEBAF opportunities

Lifetime vs. laser spot size => summer 2017 configuration (tee @ 130kV, ground anode, VWien OFF, vs. laser size)

Lifetime vs. Wien filter ON/OFF => fall 2017-spring 2018 (tee @ 130kV, ground anode, VWien ON vs. OFF)

Lifetime vs. bias anode => summer 2019 PREX opportunity (large shed @ 130kV, anode ON vs. OFF, VWien=ON)

Lifetime vs. gun voltage w/ and w/o bias anode => fall SAD 2019 opportunity (small shed @ 130kV vs. 200kV, bias=ON/OFF, VWien=OFF)

Lifetime vs. bias anode => fall 2019-spring 2020 CREX opportunity (small shed @ 130kV, anode ON vs. OFF, VWien=ON)
