  • Exploring the Nature of Matter

    Plans and proposals for the next, great physics machine for studying the intrinsic bits of everyday matter are starting to form. The proposed Electron-Ion Collider could ensure that the cutting-edge science that has kept Jefferson Lab and the United States at the frontier of nuclear physics research for 25 years will continue for decades to come.

  • The next large nuclear physics research facility being proposed to the DOE for construction is an Electron-Ion Collider (EIC). An EIC could provide unique capabilities for the study of Quantum Chromodynamics (QCD), the theory that describes how quarks and gluons build protons, neutrons and nuclei. In March 2013, NSAC ranked an EIC as “absolutely central” in its ability to contribute to world-leading science research. Two facilities, Jefferson Lab and Brookhaven National Lab in New York, are developing facility concepts.

  • A Jefferson Lab EIC would accelerate two beams of sub-atomic particles to nearly the speed of light before slamming the beams together. A stream of electrons and a stream of protons or ions would collide at two interaction points. These interaction points will be surrounded by large detectors, which will record the results of these interactions for scientists to interpret.

  • Building an Electron-Ion Collider at Jefferson Lab would capitalize on the lab’s existing Continuous Electron Beam Accelerator Facility and on the lab’s expertise in designing and building particle accelerators. The essential new elements of an EIC facility at Jefferson Lab would include an electron storage ring and an entirely new, modern ion acceleration and storage complex that would be constructed in a large-scale civil engineering project.

  • The Electron-Ion Collider is considered to be essential to the United States’ ability to contribute to world-leading scientific research. Researchers hope such a machine can help answer fundamental questions about ordinary matter, revealing for the first time and in detail how matter’s smallest building blocks and nature’s universal forces combine to build our visible universe.

  • How to use Superscripts, Subscripts, and Greek Characters, EIC2 Ω

    To add Super or Sub Scripts to the page body:

    1. At the bottom of the text editor, make sure Text format is set to "Full HTML"
    2. Use the Superscript and Subscript button in the editor (2nd line, 5th and 6th button)
    3. Example:   EIC2 H2O

    To add Super or Sub Scripts to the page title:

    1. To use sub script in the title, Use <sub> tag. For Eg: "This text contains <sub>subscript</sub> text."
    2. To use super script in the title, Use <sup> tag. For Eg: "This text contains <sup>subscript</sup> text."

    To add Greek Characters to page body: 

    1. To greek characters, copy past from the URL: https://www.w3schools.com/charsets/ref_utf_greek.asp   Ex, Ω β ψ

    To add Greek Characters to page Title: 

    1. Copy and paste the characters into the title just as the above step. 

     

     

     

     

     

  • Detector Testing Capabilities in Hall B

    Detector testing capabilities in Hall B (Summer 2020)

    Space available is indicated on the drawing: https://www.jlab.org/sites/default/files/eiccenter/HallBTesting.png

    - Area A and B are non-invasive or minimally invasive which can run with CLAS12 simultaneously. Area A is for small setups. Area C is for dedicated tests which cannot run simultaneously with CLAS12.  

    - For parasitic noninvasive or minimally invasive tests.

    Small setups can be placed upstream of CLAS12 target at the location of BAND. If BAND is used they can be placed just upstream of it or just downstream. They will see particles coming from the target at large angles. In principle some small detectors can be placed in front of  FTOF where we don't have LTCC or RICH installed, at the edges of the sector.

    - Larger setups can be installed on the platform between the forward carriage and downstream alcove with some modifications of the downstream beam line. In this case they will see what is going at small angles and/or additional scattering chamber with thin target could be installed there.

    - For dedicated test in addition to this location we can use space between the tagger and the solenoid.

    - Space downstream of the CLAS12 detectors. For example, behind the calorimeters, we have enough space to test any type of muon detectors (small ones can be mounted directly on the forward carriage, large ones on some platform downstream of the forward carriage). Another good space we have is between R3 drift chambers and FTOF for sectors that do not have LTCC or RICH. In both places, we know particle type and momentum before the detector. Nice place for a tracking detector test.

    Some caveat:

    - In location A the composition of particles is not really known. This place can be used if they want to test detector operation in magnetic field. This place is for small detectors only.

    - In  location B the secondary target (foil or wire) can be installed. This will allow to estimate flux of particles. This place can be used for instance to test tracking detectors.

    - Space between CTOF/CND PMTs and BAND. It is a high magnetic field area, and close to sensitive SVT electronics. Not so simple to do tests of a detector that may require frequent access or may generate electronic noise. 

    Engineering support: Bob Miller can provide engineering support and design support stands for these experiments.  We do have a couple of stands left over from CLAS that may be useful.  

    DAQ: Hall-B staff could provide  full support for daq/trigger. Depending on actual setup we may need to buy some hardware

    HV power supplies to operate PMT-based detectors: we can provide some if number of channels is not too large
