Exploring Collider Interaction Regions in High Energy and Nuclear Physics
This course delves into the physics, design, and operational aspects of Beam Delivery Systems, Interaction Regions, and Machine-Detector Interfaces in various colliders. Students will learn about collider components, machine protection, simulation codes, and modern techniques to safeguard against impacts from high-intensity beams. Prerequisites include a background in classical mechanics, electrodynamics, and accelerator physics. By the end of the course, students will grasp the functioning of high-energy colliders and be familiar with current and upcoming collider projects.

Collider Interaction Regions for High Energy and Nuclear Physics by Yulia Furletova (JLab), Nikolai Mokhov (FNAL) and Michael Sullivan (SLAC) USPAS Winter, Feb. 7-18, 2022
Purpose and Audience (1) The purpose of this course is to introduce the students to the physics, design, technology and operational experience of the Beam Delivery System (BDS), Interaction Region (IR) and Machine-Detector Interface (MDI) of pp, proton-antiproton, Heavy Ion, e+e-, electron-ion and + - colliders. This course will review the history of colliders, present the major achievements of operational machines and the key features of near-term collider projects that are currently under development in both high-energy and nuclear physics. We will also briefly overview future project directions in High Energy Physics (HEP) and Nuclear Physics (NP). 2 N. Mokhov | USPAS: Collider IR, Introduction 02/07/2022
Purpose and Audience (2) Fundamental interactions of beam particles with material of collider components are described along with the consequences of controlled and uncontrolled impacts of high-intensity or/and high-power or/and high-energy beams on components of accelerators, beamlines, target stations, beam collimators, absorbers, detectors, shielding, and environment which can range from minor to catastrophic. Methods to protect collider components machine protection and collimation systems - are described in detail along with modern simulation codes used for design of such methods. 3 N.

Prerequisites, Objectives, Credit Requirements The focus of the course is collider interaction regions (IR). Courses in classical mechanics, electrodynamics, special relativity and physical or engineering mathematics, all at entrance graduate level; and the USPAS course Fundamentals of Accelerator Physics and Technology with Simulations and Measurements Lab or equivalent familiarity with accelerators at undergraduate or graduate level are required. It is recommended that students have general familiarity with physics of particle passage through machine components both through their aperture and outside in presence of electromagnetic field as well as modern codes allowing to do accurate modeling of all underlying physics. It is the responsibility of the student to ensure that they meet the course prerequisites or have equivalent experience. Objectives On completion of this course, the students are expected to understand the physical principles and techniques that make high energy particle colliders function, become familiar with leading operational and near-future colliders (LHC, SuperKEKB, EIC, muon colliders etc); Credit Requirements Students will be evaluated based on the following performances: Homework assignments (60% course grade), Final exam (40% course grade) 4 N.
