The Muon Trap, or just the Ghost Trap is one of the tools used in capturing ghosts.
The Trap is a sealed container that allowed the Ghostbusters to transport the spirits to the Containment Unit, where they would be released into the grid. It is unclear what happens to the trap once placed inside the grid, though some have theorized that when a captured ghost is put into the Containment Unit, the entity is pumped out of the trap cartridge so it can be used again.
Once a trap has captured a ghost and has closed, it cannot be re-opened without releasing the ghost contained within. For this reason, the Ghostbusters must each carry several traps. They must dispose of a trap once it is used.
Design and Use
Ray Stantz warns the other Ghostbusters not to look directly into the trap when it is open. Egon Spengler does just that, but suffers no ill effects. However, it’s believed that if anyone should look in the trap for too long, they will go blind. Also, some have speculated that prolonged viewing of an active ghost trap, the trap will suck out and imprison the viewer’s soul. This idea has never been proven…
Capturing a ghost occurs in three steps:
- Zap ’em – Fire a Proton Stream at the ghost until they lose sufficient P.K.E.
- Cap ’em – Activate a Capture Stream holding the ghost in place.
- Trap ’em – Activate the trap and move the ghost to the storage facility.
In the 1990s, the standard foot activation pedal was replaced with the Sensor Activation System – a red beacon signal coming from the trap itself that would open and slowly suck a ghost in when in a certain proximity. However, the Ghostbusters must use the Capture Stream to keep the ghost in the containment cone the trap releases, thus “forcing” them in.
