Emails/attachments sent during the previous week

• Email chain subject name: GPT & IBSIMU Temporary Shared Folder
  • Date: Dec 12, 2019
  • Description: OneDrive folder created for sharing large attachments - workaround for uploading files larger than 300MB to wiki
• Email chain subject name: Re: Re: Re: Re: ……….. (my notes)
  • Date: Dec 10, 2019
  • Description: Shared Python code for creating standard output plots (x,y,x',y',etc.)
• Email chain subject name: Electrostatic model assembly file and tutorial by Gabriel
  • Date: Dec 13, 2019
  • Description: Carlos shared Gabriel's T-Cathode model on the wiki and sent a pdf with a summary of the model

Post-meeting notes

• Need to make ppt slide showing CST model with Rmax regions (regions where particles are removed), and where E-field is defined
• Create a "killmap" (Map3D_Remove GPT function) from stepfile?
• Solenoid and second steerer field maps are overlapping...perhaps move second corrector upstream to z=0.5m? - need same kicks on both correctors so that the beam returns to center
• Perhaps use physical values of steering coils (in G-cm)
• Make plot of Cristhian's B & Φ on axis (including solenoids, correctors, and E-field)
• Start at 135mm with correct particle distribution (i.e. use screen at z=135mm) for easy comparisons with IBSimu
• Correct x vs y plot (Python) - update axis labels
• Pick solenoid lens setting for small beam at dipole
• Fix 15 deg dipole field map link (wasn't working at time of meeting) and upload to wiki w/comment
• Figure out cause of bump in RMS emittance plot
