Leak Detection Trainer
He Leak Detection Trainer
Find the leak! A helium leak is hidden at one of the seals or joints in the vacuum system below.
Move your virtual He spray probe over the schematic and watch the RGA mass-4 signal on the strip chart.
When the signal rises, you are near the leak. Click a component to guess the leak location.
Fewer wrong guesses and faster times earn higher scores.

Leak Checking Technique
Spray pattern: Always spray He systematically from top to bottom, outside to inside.
He is lighter than air and rises -- if you start at the bottom, rising He contaminates upper seals and gives false positives.
Response time: There is a transport delay between when He reaches a leak and when the RGA detects it.
Larger leaks respond faster. Move the probe slowly and wait for the signal to develop.
Signal decay: After moving away from a leak, the He signal decays exponentially.
The pump-down time constant depends on pumping speed and system volume. Be patient before moving on.
Difficulty levels: Gross leaks (1e-6) are easy to find -- the signal jumps immediately.
Micro leaks (1e-10) require patience and systematic scanning; the signal barely rises above noise.
