Global Direct Collider with Immediate Consequences

Abstract

The International Linear Collider (ILC) is a significant upcoming particle accelerator designed for electron-positron collisions, with a target energy exceeding 1 TeV. It is a key complement to CERN's LHC accelerator complex and provides crucial opportunities for furthering high-energy physics research. In contrast to the ILC, the Compact Linear Collider (CLIC) at CERN, with a planned collision energy of 3 TeV, offers an alternative approach. The ILC is projected to be at least 30 kilometers long, potentially extending to 50 kilometers, with the use of advanced superconducting microwave resonant cavities made from ultrapure niobium or Nb3Sn. These cavities will operate at gradients exceeding 35 MV/m, with some designs targeting 50 MV/m. Construction of the ILC is scheduled for Japan, spanning from 2016 to 2026, and if successful, Japan will emerge as a global leader in accelerator technology, joining CERN and the United States. Polish research teams from institutions like IFJ-PAN, AGH, UJ, NCBJ, UW, PW, PWr, and INT-PAN are actively involved in this global endeavor, contributing to the design and development of systems for the ILC.
