 Thu Jun 29 12:05:45 2023, Alex M, Gain at various source heights 17x
|
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.

Fri Jun 2 00:21:36 2023, Ryan Debolt, Error test results
|
Attached is a plot containing bar graphs with error bars representing the average number of generations it took for the GA to achieve a chi-squared value
of 0.25 (roughly equated to a 0.8 out of a max 1.0 fitness score). Unlike the fitness scores used by the GA, these values do not have simulated error attached
to them and are therefore a better measure of how well the GA is optimizing. These results were obtained by running 10 tests in the test loop for each |

Mon May 29 20:21:07 2023, Dylan Wells, Pueo Physics of Results Plots 7x

The Physics of Results Plots have been added to the Pueo Loop. The current version of the plotter is built for pueoSim v1.0 and located in ${WorkingDir}/Antenna_Performance_Metric
(Hasn't been pulled into the loop directory yet).
The pueoSim v1.0 IceFinal files were missing information on the RF direction and information needed to see an amplitude spectrum. I asked Will, |

Thu May 25 15:36:54 2023, Ryan Debolt, Byran Reynolds, preliminary error tests (PUEO) 8x
|
Here are some preliminary results from testing the effect of error on growth in the GA. For this test, we start with a simulated error of 0.5 because
our true fitness score is bounded between 0.0 and 1.0. From here, we simulate doubling the number of neutrinos by reducing the error by root(2), then root(4),
and observed the growth on the fitness scores plots. We did these three tests with both 50 and 100 individuals (plots starting with 30 use 50 and starting |

Here is a list of things we agreed to do before starting a new PUEO run. Feel free to add notes here as things are done and we will revisit the
list next week.

In this post, I'm going to give step by step instructions on everything you need to do to run the loop. See Julie's
thesis for the most recent iteration of this manual. Also refer to entry 123 for a list of some errors we have encountered historically in the loop and
how to resolve them, though some fixes may be outdated. |

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

Mon May 1 05:45:02 2023, Alex M, Midscale PUEO Run
|
I've started a run of the PUEO loop to get some data for evolving the antenna width and height. We are running with 24 individuals, each with 400k
neutrinos at an energy exponent of 19. Here is the output directory: /fs/ess/PAS1960/HornEvolutionOSC/GENETIS_PUEO/BiconeEvolution/current_antenna_evo_build/XF_Loop/Evolutionary_Loop/Run_Outputs/2023_05_01_Test_5
It's very important to note that the cross-pol data being used still comes from the data already stored in pueosim. This is because our extremely |

Sun Apr 30 03:45:07 2023, Alex M, Preliminary PUEO Run
|
We have the PUEO loop in working order, though there are a few errors in accuracy and efficiency. We started a preliminary run with few individuals and
neutrrinos as a large scale test that may still give us some useful data.
For this run, we are only evolving the inner side length (10cm to 25 cm) and height (10 cm to 50 cm). The walls are slanted at 45 degrees, so |

Thu Apr 27 01:36:32 2023, Alex M, Results from paper symmetric run
|
The reviewer asked us to run the loop again but for just symmetric antenna designs. We have completed that run and have results ready. We still need
to resimulate the top five individuals, which I'll update this post with later. I attached the violin plot (though it should be fixed to not let the
legend overlap the data). See this previous entry for the details of the run: http://radiorm.physics.ohio-state.edu/elog/GENETIS/198 |

Tue Apr 11 00:36:49 2023, Bryan Reynolds, AREA physics of results plot first look

After some work, I've gotten the physics of results plotting script provided by Dennis working to compare the ARASim outputs from an AREA run to
a set of reference data for the ARA bicone (provided by Alex). Among the outputs is a histogram of of events triggered vs cos(theta_nu) (attached here).
This is the plot that was previously presented in GENETIS talks in the physics of results discussion. |

Work in progress. Update on H-pol XF design. The first plot is the gain pattern with ferrite rod sets (blue) vs. with nothing but the copper plates.
The second plot is the gain pattern with everything but the ferrite rod sets vs. with nothing but the copper plates.
The ferrite rod sets function to narrow the gain pattern. |
