The AIACE experiment summary



Our Mission

AIACE participates into a vast program to probe the nuclear matter using high energy electrons and photons. It's main goal is to fully investigate the following areas:

  •  Elementary and nuclear excitations of N* resonances;
  •  Spin structure functions of the nucleon;
  •  Inclusive electron scattering on nuclei;
  •  Elementary and nuclear hyperon production and decays;
  •  Structure of the few body systems (3 quark and few nucleon systems);
  •  Nuclear medium effects (modification of the nucleon properties, correlations);

For detailed information refer to the Program Advisory Committee page.

The Experimental Site

The Jefferson Lab (Newport News, Virginia, USA) was formerly known as CEBAF: Continuous Electron Beam Accelerator Facility. It is a world class nuclear physics research facility managed by the DOE (US Dept. Of  Energy) and SURA (South-Eastern Universities Research Association).

The Jefferson Lab electron accelerator has a maximum energy of 6 GeV and nearly 100% duty cycle. The primary beam is divided to the three experimental Halls equipped with complementary detector setups in order to allow the widest range of scientific investigations.

The Hall B physics program was outlined above and is carried out at the using the CEBAF Large Acceptance Spectrometer (CLAS) installed in the Hall B.


Hall-B: The CLAS Detector

is a large acceptance spectrometer equipped with  6  superconducting coils which generate a toroidal magnetic field. Its primary goal is to carry out experiments which require the detection of several, only loosely correlated particles in the hadronic final state, and measurements at medium and high luminosity.

AIACE contributions to the Hall-B

AIACE to the CLAS collaboration concerns both the data analysis effort and the experimental equipment since AIACE has provided several components of the CLAS detector such as:

Future Plans

The energy of the continuous electron beam serving the JLab experimental Halls will be raised from 6 to 12 GeV and an additional experimental hall will be built (Hall-D). Information regarding the physics program of the upgrade and the CLAS detector improvements connected to the accelerator energy upgrade can be found here.
