We have measured the mass of Z boson to be 91.11±0.23 GeV/c2, and its width 1.61+0.60−0.43 GeV. If we constrain visible standard-model value, find partial invisible decay modes 0.62±0.23 GeV, corresponding 3.8±1.4 neutrino species.Received 24 July 1989DOI:https://doi.org/10.1103/PhysRevLett.63.724©1989 American Physical Society
This report presents a brief summary of the science opportunities and program polarized medium energy electron-ion collider at Jefferson Lab comprehensive description conceptual design such based on CEBAF electron accelerator facility.
A conceptual design is presented of a novel energy-recovering linac (ERL) facility for the development and application energy recovery technique to linear electron accelerators in multi-turn, large current regime. The main characteristics powerful experiment (PERLE) are derived from Large Hadron Collider, an beam upgrade under study LHC, which it would be key demonstrator. PERLE thus projected as investigate efficient, high (HC) (>10 mA) ERL operation with three re-circulation passages...

In the past decade, nuclear physics users of Jefferson Lab's Continuous Electron Beam Accelerator Facility (CEBAF) have benefited from accelerator advances and machine improvements. As early 2011, CEBAF operates routinely at 6 GeV, with a 12 GeV upgrade underway. This article reports highlights CEBAF's scientific technological evolution in areas cryomodule refurbishment, RF control, polarized source development, beam transport for parity experiments, magnets hysteresis handling, breakup,...
Cooling of hadron beams is critically important in the next generation storage rings for delivery unprecedented performance. One such application electron-ion collider presently under development US. The desire to develop electron coolers operation at much higher energies than previously achieved necessitates use radio-frequency (RF) fields acceleration as opposed conventional, electrostatic approach. While cooling a mature technology low energy utilizing DC beam, RF requires beam be...
Beam quality preservation during transport of high-brightness electron beams is general concern in the design modern accelerators. Methods to manage incoherent synchrotron radiation (ISR) have been place for decades; as beam brightness has improved coherent (CSR) and microbunching instability (uBI) emerged performance limitations. We apply compensation analysis diMitri, Cornacchia, Spampinati - previously used by Borland systems use with low-emittance beams, find that appropriately...

This paper describes the design and implementation of a beam loss accounting system for CEBAF electron accelerator. samples current throughout path measures accurately. Personnel safety machine protection systems use this to turn off when hazardous losses occur.
A successful GeV scale energy recovery demonstration with high ratio of accelerated-to-recovered energies (50:1) was recently carried out on the CEBAF recirculating linear accelerator. Future (multi-GeV), current (hundreds milli-Amperes) beams would require gigaWatt-class RF systems in conventional linacs - a prohibitively expensive proposition. However, invoking alleviates extreme power demands; required becomes nearly independent beam current, which improves linac efficiency and increases...
