  • HALL D INFORMATION

    Hall D is dedicated to the operation of a large-acceptance detector for experiments with a broad-band, linearly-polarized photon beam produced by ~12 GeV electrons from CEBAF.

  • 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
