Room is fixed by holder.Connect ionization chamber and measure system.Adjust two grades of pole article carrying platforms and three grades of poles
Article carrying platform position so that (cross laser center is i.e. X-ray main beam center at cross laser center
Position) impinge upon the sensitive volume center of ionization chamber.
Open X-ray ray machine afterwards, X-ray machine parameter is set, rotate additional filtration rotating disk required in experiment
At specification.Carried out X-axis by motor software control one-level article carrying platform and move to operating position.Then
Proceed by ionization chamber ionization current to measure, measure complete under this specification, preserve data.Adjust X-ray again
Machine parameter, adjusts X-axis position, measures different specification.
Due to the difference of the type kind of ionization chamber, the specification of measurement is different, it is therefore desirable to penetrate in distance X
The various location of spool measures, and that is to say the X-axis position adjustment needed during measuring.By
In the difference of the size of ionization chamber, for making the sensitive volume of ionization chamber be positioned in X-ray main beam
Heart position, the most different ionization chambers needs to carry out the position adjustment of different Y-axis and Z axis.
Moving with Z axis eventually through completing Y-axis, the sensitive locations carrying out ionization chamber is in X-ray beam
Center.Moved by the position of X-axis, complete the measurement of different ionization chamber different specification.
