 Tue Jan 31 15:31:29 2023, Alex M, ARA Bicone Responses
|
Here we will record where we obtained the ARA bicone antenna response files we use as our baselines. We want to record where we found them/who gave them
to us and how they were generated (either through simulation or from actual tests). |

|
Here are some ANITA/PUEO pictures that I received from Christian Mike that might be helpful. I include his descriptions as well.
The one with the black crates in the background is the ANITA 1 and ANITA 2 form factor and the one in the anechoic chamber is the ANITA
3 and ANITA 4 form factor. I dimensioned out an ANITA 3/4 antenna, in CAD space, to give you a better idea of the ridge profile. The ANITA 1/2 CAD models |

Thu Jul 2 23:13:05 2020, Amy , A useful reference on bicone antennas
|
I found this datasheet on bicone antennas, that is a useful reference for seeing the relationship between bicone dimensions and bandwidth. From
these it looks like the lower end of the band is at about f_low=c/(4*L_E), where L_E is the entire length of the antenna (twice the length of one cone),
although we'd expect the peak gain to be where a quarter wavelength is just one of the cones (and the figure may roughly support that). |

Mon Nov 8 17:04:30 2021, Ethan Fahimi, 11/04/2021 AREA run 2 violin plot
|
This is a plot made from the AREA project with full Arasim implementation with each gain pattern of each individual being fixed across all frequencies.
This run was done with 50 total individuals per generation, across 36 generations. Each individual was tested with 4 seeds of 10,000 neutrinos,
for a total of 40,000 neutrinos. For each new generation, 25 individuals were created with roulette crossover, 8 with roulette mutation, 9 with tournament |

Fri Sep 17 13:41:36 2021, Ethan Fahimi, 07/20/2021 AREA run 3 violin plot
|
This is a plot made from the AREA project with full Arasim implementation. It can be seen that the Veff of any individuals is not what I would consider
"good", nor is it really rising, it is quite flat. This is because in this version of AREA, the gain pattern at each frequency is generated differently
than each other frequency, there is no correlation. This is known and actively being corrected. This plot is of old data and was just made for two reasons: |

Tue May 9 18:09:35 2023, Alex M, 05/08/23 Pueo Run
|
Here are the run details for the latest PUEO run we've started. There are still some bugs that need to be worked out, which are detailed on the github.
Here is the directory where the data is stored: /fs/ess/PAS1960/HornEvolutionOSC/GENETIS_PUEO/BiconeEvolution/current_antenna_evo_build/XF_Loop/Evolutionary_Loop/Run_Outputs/2023_05_08
This run uses 50 individuals per generation with 400k neutrinos per individual at an energy exponent of 19. Only the inner side length and outer |
