Reverse Injection

The Tevatron sends 150 GeV protons through the A1 transfer line and into the Main Injector. A program called Injection Closure uses the protons to make suggested A1 line magnet adjustments to the particlesí incoming angle so that they match with the Main Injector. An operator looks at the suggestions and chooses to accept them or not. (Protons are used for this tune up because they are cheaper to use than antiprotons.)
