  2. Aim of Previous Week • The focal points of our studies are: • Electric Field Studies • Signal / Energy Deposition Studies • Magnetic Field Studies A lot of progress in all three fronts!

  3. Geometry of LIC

  4. Electric Field Studies • Implemented a new field map (thanks to Juan again) for the Electric field between the electrodes • Created some nice images of the field using that data • Re-drew the historams for the signal when shooting in the center, at the edge and just outside of the electrodes of LIC

  5. Field for z=0.5 mm

  6. Electric Field Studies

  7. Signal Studies • We are interested in comparing the signal of LIC in three different cases: • Ionization processes only • All EM processes • Full EM plus hadronic processes

  8. Include hadronic processes • For the hadronic case, found the best library for the energy range of interest [0-10 GeV]: Bertini

  9. Signal with EM only

  10. Signal with hadronics

  11. Signal Studies • The signal when the hadronic processes are added is stronger (~10%) than with only EM • Also, its shape gets Landau-like instead of almost gaussian (EM-only case) • Some very energetic events with a huge signal

  12. Magnetic Field Studies • Added a magnetic field in the entire volume of LIC • Verified that both the B-Field and the E-Field in LIC co-exist peacefully • Ran simulations with a constant magnetic field of values: 0 tesla, 0.01 tesla, 0.1 tesla and 1 tesla with a relatively narrow beam ( beam width: 0.5 mm) aiming at the center of the electrodes

  13. Magnetic Field Studies • When shooting at the center of the electrodes, no difference in the signal with a magnetic field up to 1 tesla. • What would happened if the beam was as wide as the electrodes (37.5 mm)?

  14. Work still in progress • Get a map for the E-field in the entire gas-filled volume of LIC to see if we get extra signal from the feedthrough • Run some many-event runs for better statistics • …
