Vacuum chamber leak checking |
|
|
| On Tuesday I had isolated the main volume and let it pump down over-night. Today, Wednesday, I checked it and it had only gone down by a small amount compared to when I left it on Tuesday.
I then proceeded to tighten down the bolts attaching the tubo-pump to the zero-length reducer while it was under vacuum. This caused the pressure to drop down a few orders of magnitude. |
