[Ma, Luis]

February 20, 2025 - 3:30 PM

Ma performed an RGA scan with the vacuum system containing the heater elements. The results are attached below.

Pressure (Torr) Temperature (°C)
RGA Volume 5.70 × 10⁻⁹ 23
Main Volume 1.87 × 10⁻⁹ 23

As we can see, we are not yet under cleanliness standards. The passing threshold is 4 × 10⁻¹⁰, we are very close to it.
