- Modeling Updates
- Gabriel/Josh learn running existing CEBAF GPT deck from Gun to Chopper (130 kV, cathode no-shed?, anode grounded, solenoids, Jay Wiens?)
- Gabriel's 200kV upgrade studies
- 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 studies (*data taken already)
- *Laser spot size => summer 2017 configuration (tee @ 130kV, ground anode, VWien OFF, vs. laser size)
- *Wien filter ON/OFF => fall 2017-spring 2018 (tee @ 130kV, ground anode, VWien ON vs. OFF)
- Bias Anode OFF (Part I) => summer 2019 PREX opportunity (large shed @ 130kV, anode OFF, VWien=ON)
- Bias Anode ON (Part II) => fall 2019-spring 2020 CREX opportunity (small shed @ 130kV, anode ON, VWien=ON)
- Gun voltage (bias on/off) => fall SAD 2019 opportunity (small shed @ 130kV vs. 200kV, bias=ON/OFF, VWien=OFF)
