Overview
This page displays temperature and pressure logs recorded during bakeout
procedures of the UHV chamber. Each log file covers one bakeout session.
Temperature sensors are plotted against the left axis;
chamber pressure against the right (logarithmic) axis.
The two summary cards at the top always show the most recent highest
temperature and the most recent pressure reading.
Selecting a log file
On desktop the file list is in the sidebar on the left.
On mobile use the Logs dropdown button. Files are sorted
newest-first; the most recent file loads automatically. The active file
is highlighted in blue.
Pan mode (default)
When Pan is active:
• Left-click / touch-drag to pan.
• Scroll wheel to zoom in/out.
• Pinch on touch screens to zoom.
On mobile, tap the chart to show sensor values — the tooltip disappears
automatically after one second.
Select mode
When Select is
active, click and drag to draw a rectangle over the region of interest —
releasing zooms into that exact area.
Reset
Reset restores the
full view at any time.
Reading the axes
Left — Temperature (°C): linear, auto-scaled.
Right — Pressure (mbar): logarithmic, auto-scaled.
Noise floor 10−12 mbar.
Tooltips
Hover (desktop) or tap (mobile) the chart to see all sensor values at
that timestamp, sorted highest temperature first, pressure last.
On mobile the tooltip hides automatically after one second.
Log file format
Tab-separated text (ISO-8859-1 / Latin-1 encoded). Header line starts
with #. Column 0 = timestamp
(DD.MM.YYYY HH:mm:ss), column 1 = pressure,
remaining columns = temperatures. Missing values stored as
- are skipped.
Troubleshooting
Expand the Debug Log panel at the bottom of the page
for a full trace of the loading and parsing steps.
