Description

Take a working macros for simulation for EXP1904. It may be found in

expertroot/macro/EXP1904_H7/sim

branch

406_exp1904_h7_sim

Step by step employ following changes:

  1. delete the central telescope;
  2. change the thickness of veto detector (third layer of side telescopes) to 10 cm;
  3. introduce the reaction 6Li + p --> 6Be + n with subsequent decay 6Be --> 4He + p + p;
    • the decay occurs in the point of the reaction;
    • beam cross-section is infinitely small;
    • beam direction coincidences with the Z-axis in laboratory system;
  4. delete the beam detector (ToF system and MWPC's)
  5. reconstruct the 6Be invariant mass under conditions:
    • only one particle per telescope was registered;
    • beam energy and size is constant and known;
  6. replace the third layer of telescopes by CsI detector;

Provide results of steps mentioned above in individual comments.
