TOF Response

In order to calibrate the TOF energy response it is necessary to compare the data to Monte Carlo (MC) simulations. Only through the comparison with MC data can we find the conversion from ADC integral to Energy in units of GeV or MeV. Because the TOF is close to the forward calorimeter (FCAL) it is necessary to use tracking to define a good sample of minimum ionizing particles with defined impact angle that cause hits in the TOF. This is shown below using MC data for paddle 1, 5, 10, 15 and 18 where paddle 1 is the furthest away from the beam and paddle 15 closest of these four paddles.
