Elastic Collisions: Case Study

Elastic Collisions: Case Study

Elastic collision of a system demands conservation of both momentum and kinetic energy. To solve problems involving one-dimensional elastic collisions between two objects, the equations for conservation of momentum and conservation of internal kinetic energy can be used. For the two objects, the sum of momentum before the collision equals the total momentum after the collision. An elastic collision conserves internal kinetic energy, and so the sum of kinetic energies before the collision equals...

Elastic Collisions: Introduction

Elastic Collisions: Introduction

An elastic collision is one that conserves both internal kinetic energy and momentum. Internal kinetic energy is the sum of the kinetic energies of the objects in a system. Truly elastic collisions can only be achieved with subatomic particles, such as electrons striking nuclei. Macroscopic collisions can be very nearly, but not quite, elastic, as some kinetic energy is always converted into other forms of energy such as heat transfer due to friction and sound. An example of a nearly...

Area of Science:

High-energy particle physics
Collider physics

Background:

The ATLAS experiment at the Large Hadron Collider (LHC) collects vast amounts of data from proton-proton collisions.
A sophisticated trigger system is essential for filtering relevant events from the high collision rates.
Upgrades were implemented during the LHC's first long shutdown to optimize data acquisition.

Purpose of the Study:

To present an overview of modifications to the ATLAS trigger and data acquisition systems.
To evaluate the performance of the trigger system and its components using 2015 data.

Main Methods:

Analysis of proton-proton collision data recorded by the ATLAS experiment in 2015.
Assessment of the trigger system's efficiency and performance metrics.
Review of system changes implemented after the LHC's first long shutdown.

Main Results:

The ATLAS trigger system successfully selected high-quality data at a reduced rate of approximately 1 kHz from up to 40 MHz of collisions.
Performance evaluation confirmed the effectiveness of the trigger system and its components with the recorded data.
The implemented system changes were integrated and functional during the 2015 data-taking period.

Conclusions:

The ATLAS trigger and data acquisition systems were successfully upgraded and performed effectively during the 2015 LHC run.
The system's ability to handle high collision rates and select significant events was validated.
These findings contribute to the ongoing analysis of physics at the LHC.
