We are almost to where we can start the physical building of the antenna!
I've attached all the information I currently have regarding the building project. Some of it is messy work notes and some is well-structured.
I’ve attached the following files for the GENETIS building project: |

Here are some scholarships available to physics majors I've been lucky enough to receive throughout undergrad that allowed me to work on this project
unpaid without needing supplemental income from a separate job or loans.

# AraSim CSE Spring 2024 Work
## Goals
The main goal was to get a working multithreaded version of the AraSim codebase working. Doing this, the hope was to learn how to multithread the |

Fri Sep 1 09:16:30 2023, Alex M, Curved Run With Realized Gain
|
We are beginning a new run with several improvements to the ARA VPol loop to try to evolve antennas that are optimally matched just by their geometry.
To do this, we are evolving with the RealizedGain instead of just Gain in the Xmacros (thus taking into account impedance mismatch). We also have the speed
up that parallelizes the AraSim jobs on each run. Attached is the run_details.txt file, but the GA parameters are subject to change. Here is what they |

Attached is the license agreement that each person should sign to be able to use XF on OSC. You can sign it, send it to Amy, and she will return
it to OSC with her signature on it. |

Wed Aug 2 12:49:57 2023, Dylan Wells, Line of Best-Fit Straightened Sides Antenna
|
Previously, we have tried to straighten the sides of the best-evolved curved antenna in elog
229. However, there were potential issues with how closely this line resembled the curve of the antenna.
So, I attempted to create another straightened sides antenna using a linear regression model to find the best fitting line for the curve to create |

I've been building in XF and have ran into some issues but currently have the following completed:
- Struts are placed, though they are not evenly spaced and the same. I have contacted XF to try and figure out how to get rotation/patterns to
do what we need |

Tue Jul 18 22:04:22 2023, Dylan Wells, Parallelizing pueoSim jobs
|
Currently, the PUEO loop runs pueoSim with 1 pueoSim process per job submitted.
Each of these jobs has 1 node and 8 cores, however, pueoSim only needs a single core to run.
Here is some data I collected by running the same seed of pueoSim with different numbers of cores in the job: |

After discretizing and straightening the sides of the curved antenna that performed the best (Generation 13, individual 84) and running the antenna through
AraSim, the following results and physics plots were generated. |

|
Here are a collection of antenna gain patterns with the antenna power source located at various heights at 500 MHz. The heights are indicated in the
name of the images and were located at 3cm, 6cm, 12cm, and 24cm from the base. One thing to note is that the power source becomes longer as a function
of height (since it's connected to the ridges, which slope back). |

Sun Jun 18 21:32:03 2023, Dylan Wells, Default Toyon Antenna Simulation
|
To act as our comparison to the evolved antennas while plotting, we have done a simulation of pueoSim with 4,000,000 neutrinos for the measured toyon
gains found in /fs/ess/PAS1960/buildingPueoSim/pueoBuilder/components/pueoSim/data/antennas/measured
In order to run the jobs, I used the runJobs.sh script found in /fs/ess/PAS1960/buildingPueoSim which submits job runs of 40,000 neutrinos |

|
Here are my recommended starting genes for the initial generation of the upcoming run (confirmed that these will produce a working antenna in XF). We
want to use the lowest values we can because we expect that a larger (namely, taller) antenna will perform better:
S, H, x0, y0, yf, zf, beta |

Mon Jun 5 15:00:07 2023, Ryan Debolt, Github tests
|
We want to automate tests in pull requests in GitHub to run unit tests on individual functions to ensure they return the expected results. This will
help prevent bugged code from being pushed to working branches. We will add a list of unit tests to this ELOG as we design them.
