 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. |

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). |

This paper discusses some initial HPol designs that were tested in a prototype station of ARA.
We went with the slotted cylinder design. |

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 |

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.

Mon Jul 1 13:45:49 2019, Alex Patton, Status on optimizing AraSim
|
We ran valgrind (a profiler) on AraSim to find out where it was spending most of its time, we ran it with callgrind to give an output file of the time and
opened that file with qcashegrind to display it in a legible format. This let us know that the function Param_RE_Tterm_approx was taking up about
75% of the time because it was being called hundreds of millions of times. Now more specifically the standard math functions pow() and exp() were being |

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 |

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 |
