Continued working on fixing bugs with Alex P. I had a run from over the weekend which got
through a few generations, but we're suspicious because the effective volumes are very high despite the antenna dimensions being very small. I made |

I wasn't available in the morning. I met with Amy and Alex P around 1 to talk
about how to use the AraSim function for throwing the same neutrinos to search for bugs in the loop. We want to compare three types of antennas we've |

Worked to run the loop with Alex P to test a smaller initial mean and standard deviation of
the opening angle. Worked some more on the paper too--I fixed some citations issues (and found some good ones to add) but the references are still spilling |

I worked on fixing the AraSim issue today. I think I have it resolved. Essentially, I made a second set of flags that the loop will
look for and use the first set of flags to tell the loop which error files to look at to look for the phrase "segmentation fault." If it sees |

Worked with Alex on finding the variables Amy suggested to us in AraSim. We found the Efield and max peak voltage variables and
printed them, comparing three antennas: a small one with normal veffective (nonzero), a small on with 0 veffective, and the actual bicone. The electic |

Helped Alex P try to figure out how to get data Amy was asking us to get for comparing antennas in AraSim. We've been stuck

Talked with Alex about results from a run of small antennas where we decreased the grid spacing. The average gain plots look different,
but I don't know yet if it's definitely resolved the problem because we're still getting a decent spread on the effective volumes. Helped Eliot |

getting started on learning about the algorithm and testing out the scripts. Once they play with it and can get it running they'll start running it |

Met with Alex P. and Amy to think about how we can make sure the data coming from AraSim makes sense (specifically, to figure out
why we're getting effective volumes of 0 on some antennas). Amy suggested we use a function in AraSim that let's us simulate identical events so |

Worked with Alex P on fixing a new issue that appeared in AraSim. We were getting effective
volumes of 0 in generation 4, despite getting nonzero fitness scores in previous generations. We made a fix that seems to give *some* non-zero effective |

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 |

We are currently running the loop using the improved parameters. The parameters are as follows:
50 individuals
80/20 Roulette/Tournament
6% Reproduction, 72% Crossover, 22% Mutation
Also note that individual 5 of generation
1 had its fitness score altered because one of its AraSim jobs didn't finish in time (and we would have had to wait 5 hours for it to rerun). |

Mon Oct 24 16:07:22 2022, Dylan Wells, Creating the matching circuit design
|
The first part of designing the matching crictuit was choosing a frequency range to match over. We chose 100 MHz to 1000 MHz.
The geometric mean of this range in 316.227 MHz, which is the ideal frequeny to match to.
Then, we need the impedance of the antenna we are matching to. |
