The popular understanding of a particle beam as a threadlike one-dimensional strand of energy isn’t wrong, but from the point of view of accelerator scientists, it’s a bit simplistic. Particle beams are nearly always carefully formed structures, especially in the space surrounding the point of their collision. Pinched here, stretched there, particle beams are crafted […]
Onward and upward into the terascale
The 1-TeV upgrade challenges scientists develop better beams at lower rates of power
The technical design of the International Linear Collider is nearing completion, and it comes with a stipulation: If the Large Hadron Collider should direct scientists to an energy range beyond what the ILC accommodates, they should refer to its 1-teraelectronvolt contingency plan. Over the next several months, researchers will complete a preliminary study of the […]
Extending the energy reach of the ILC
The GDE design for the ILC as presented in the Reference Design Report (RDR) is for an electron-positron colliding beam facility having a maximum centre-of-mass energy of 500 gigaelectronvolts (GeV). No design or upgrade path to 1 teraelectronvolt (TeV) was presented in the RDR. However, the option to upgrade to higher energies was explicitly maintained […]
Energy Upgrade
Director’s Corner 23 February 2006 Barry Barish Energy Upgrade "Independent of the results from the first few years of running there are several reasons for an energy upgrade. Examples include higher sensitivities for anomalous gauge boson couplings, measurement of the Higgs boson self coupling, the coupling of the Higgs to the top quark, production thresholds […]
