Figure 43-6. Pristine Beam Tool - B
EAM SETTINGS SCREEN
The beam settings which need to be specified before performing an irradiation with
the Pristine beam tool are the following:
Nozzle Beam Current (nA): this parameter indicates the proton beam current as
measured in the nozzle (note that this is not the same as the cyclotron current).
It can be modulated in order to avoid saturation of the dosimetry equipment
used to perform the measurement.
Range (MeV or mm): this parameter characterizes the depth of penetration,
which is specified in g/cm², corresponds to the penetration depth of the proton
beam in a water equivalent material. As such, the range may be measured as a
linear distance in water (mm). When measuring the depth dose distribution, the
range corresponds to the depth of the distal 90% isodose in water. Conversely,
the beam may be characterized by the proton beam energy (MeV).
Irradiation time (minutes): this parameter is used to limit the irradiation time, as
an irradiation which is excessively long could be harmful for the ICs.
Beam Spot ID
Snout extension (mm)
Gantry angle (degrees)
By clicking the Prepare button on the
BEAM SETTINGS SCREEN, the PREPARATION SCREEN
appears. This screen allows the user to prepare the nozzle and monitor beam
allocation in preparation for irradiation.
