# LINAC - Ready, Set, Smash!

Students create a working model of a linear accelerator (LINAC) using the attractive force of a magnet and conservation of momentum. They simulate particle collisions in Brookhaven’s Relativistic Heavy Ion Collider (RHIC) by aiming two model LINACs at the same target. If the timing and position are correct then a collision will occur.

Vocabulary: acceleration, attract, charge, electron, energy, ion, magnetism, momentum, repel, speed

Session Information: This activity is available in-person only.

Major Understandings

Standard 1, S2.1a Demonstrate appropriate safety techniques.

Standard 1, S2.1b Conduct an experiment design by others.

Standard 1, T1.3a Generate ideas for alternative solutions.

Standard 1, T1.2b Evaluate alternatives based on the constraints of design.

Standard 6, 2.2 Use models to study processes that cannot be studied directly (e.g., when the real process is too slow, too fast, or too dangerous for direct observation).

3.3a All matter is made up of atoms. Atoms are far too small to see with a light microscope.

4.4f Without touching them, material that has been electrically charged attracts uncharged material, and may either attract or repel other charged material.

4.4g Without direct contact, a magnet attracts certain materials and either attracts or repels other magnets.

5.1b The motion of an object can be described by its position, direction of motion, and speed.

5.1c An object’s motion is the result of the combined effect of all forces acting on the object. A moving object is not subjected to a force will continue to move at a constant speed in a straight line. An object at rest will remain at rest.

5.1e For every action there is an equal and opposite reaction.
