Mon Nov 28 10:44:27 2022, Alex M, Run Details Latest_Greatest_2022_11_26
|
Here are the changes that have been made in this (and the preceding) run relative to what we have been doing before.
The newest version of AraSim has been implemented.
This was done because AraSim has gone through significant changes since
2019 that make it more accurate and makes it run faster.
The minimum length has been decreased to 10 cm per side.

Thu Nov 10 10:42:20 2022, Ryan Debolt, Optimizations
|
This is the plot for the run type that had the best performance in the most recent optimization run that was completed. The most optimized runs from
these collections are decided by which run types achieve a chi-squared value of 0.1 in the fewest generations (correlating to about a 0.9 fitness score).
However, the genetic algorithm does not use Chi-squared directly, instead trying to maximize the fitness score (which uses a chi-squared in the denominator) |

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. |
Fri Sep 2 12:40:17 2022, Alan S, Ice Shell Around Bicone 
|
Here is a PDF with a summary/log of my work trying to integrate an ice shell surrounding the bicone antennas in the GENETIS loop. I made gain
patterns of the ARA bicone with the ice shells and without them, showing the impact of the ice on the antenna's gain. Having an ice shell
changes these patterns, which are also dependent on the radius of the shell. I showed that convergence on the gain patterns and expected features start |

Here are some reading materials about HPol antennas:
This paper discusses some initial HPol designs that were tested in a prototype station of ARA.
We went with the slotted cylinder design. |

We have started a new run. Here is the directory: /fs/ess/PAS1960/BiconeEvolutionOSC/BiconeEvolution/current_antenna_evo_build/XF_Loop/Evolutionary_Loop/Run_Outputs/2022_07_15_Latest_Greatest
This run is a substantial overhaul. It is a curved run using the latest parameters from Ryan's optimization loop. Here is a list of important
changes: |

The second-best individual in this evolution was Bicone 22 from generation 40. This individual is, in fact, a fascinating case as we shall
see. But to start the story of this individual we will go back to generation 38 in order to demonstrate some of the peculiarities.

|
This was a symmetric run that began on 9/11/2020. This run used fewer neutrinos to determine how significant the number would be on the performance of
the evolution. 30,000 neutrinos were used per individual.
10 individuals were evolved over 35 generations, using 100% roulette selection and the old mutation algorithm, where genes had a 40% chance of |
Tue Jun 28 11:35:15 2022, Alex M, Run Details: Machtay_20200831_Asym_Length_and_Angle
|
This run was conducted beginning on August 31, 2020.
Both the angle and length were asymmetric for the two cones. It was run with 10 individuals over 42 generations using 150,000 neutrinos. A penalty
was still implemented on bicones exceeding the borehole width. |
