[Shane, Luis]
Summary of the issue we've been having with the timing chassis: when we connect only the Valon 5015 to power, the timing signal comes
out of it sinusoidal as expected and the status lights are steady and all looks good. As soon as we connect the 3010 to power, the signal (both coming
out of the 5015 and coming out of the 3010) go flat and the status lights of the 5015 start to flicker.
We think what may be going on is that the 5015 |

Below is attached the ADC noise floor of two CyMAC channels vs the Red Pitaya.
The frequency resolution of these RIN spectra are 16 Hz, with N_meas = 19,308,426 for the CyMAC, and N_meas = 263,024. |

Tue Jun 17 12:46:47 2025, Tyler, Update, Electronics, CyMAC ADC Noise

Below are results from power spectra measurements of the CyMAC ADC, computed form 30 hours of time series data, compared to the performance of the Red Pitaya.
The frequency resolution for the initial Cymac CSD is 2 Hz, and 216,000 spectra measurements are averaged together. As of now, it still looks like we haven't
reached the correlated noise floor of the CyMAC. We have a few days worth of data to take from, so I'll look into using a longer period of time. |

After leaving the the chamber to bake at 120 deg C from Thursday 3:41 pm. Today I started to cool the chamber down to room temperature at
11:30 am (total bake duration: 91 hours 49 minutes). Ideally, this process should be ramped down slowly, approx. 6 degree per hour. However we had no ramping
function with out controller. The only method to tune this cool/ heat rate is to tune the PID parameters, which are:

I will be using comsol until 1:30 pm today. I will be updating the model for the heater mount to be thicker in certain areas, so that it can feasibly be
3D printed. Specifically, the radius of the center cartridge mount has been increased to add thickness to the pipe and the arms of the bridge. This will
allow us to print with a much smaller chance for error, as the printer can print objects with a minimum length of 1 mm. |
