= Preliminary data sets =

Data sets generated for the initial evaluation of the ion-acoustic response of beams consisting of 10^4^ particles entering a 30cm x 30cm x 30cm water phantom.

||= Parameter =||= Definition =||
|| X-position || Mean initial position about which the particles are distributed on the x-axis (horizontal) ||
|| Y-position || Mean initial position about which the particles are distributed on the y-axis (vertical) ||
|| Normalised x-momentum || Mean initial x-component of momentum, normalised with respect to the total particle momentum of particles ||
|| Normalised y-momentum || Mean initial y-component of momentum, normalised with respect to the total particle momentum of particles ||
|| Energies || Mean initial mean particle energy ||
|| Temporal spread || Mean particle entry time relative to time = 0 ||

Each "batch" refers to a group of runs which vary one parameter or the distribution of a parameter. For example, Batch 1 varies the mean initial energy of particles entering the phantom.


The "input file" specifies the initial positions and momenta of particles and should be read as:


`x-position [mm] | normalised x-momentum | y-position [mm] | normalised y-momentum | particle energy [MeV] | particle entry time [mm] |`


The "output file" gives a complete history of energy depositions due to the 10^4^ particles as they travel through the phantom. Each initial particle is assigned an `EventNum` between 0 and 9999. At each point where the particle (or a derivative particle radiated as a result of energy deposit of the initial particle) deposits energy as it travels in the phantom, the total energy deposit and the `x-` `y-` and `z-position` of this deposit is recorded. The `Global Time` at which the particle deposits the energy is recorded, relative to t = 0 when the first particle enters. `Delta time` refers to the time step between this energy deposit and the previous deposit by this particle. `Particle Name` specifies the type of particle responsible for this deposit. The header row of these files denote the meaning of each column.
