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
trying to figure out where all of the data is printed (there are a bunch of .cc files and quantities we aren't familiar with--for example, vmmhz in |

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 |

Spoke with Evelyn and Ryan about the paperclip antennas. They found the github repository with the files and a README so they're
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 |

I went through the current PUEO Loop and documented everything that
still needs to be accomplished before we can run.
Everything is compiled in this Google |

Mon Mar 15 13:05:22 2021, Alex M, Current Run
|
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. |

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: |

|
Physics plots were created for 300K events from the higher statistic simulation results for the 9_50, 13_84, 18_89, 19_96, and 29_87 antennae.
The simulation was inaccurate because a discrepancy exists between the higher simulation physics plots and the physics plots created for the
300K event results currently in the GENETIS Loop. This can be seen in the attached pdf file. |
