The detector system consisting of a light-tight gray PVC phantom, a transparent acrylic inner tank filled with liquid scintillator, and a CCD camera. The dashed lines represent the camera’s field of view.
A consecutive series of images of the LS detector system exposed to a 120 MeV proton beam. Each image represents the total light output seen within a 100 ms time interval.
Depth scintillation light profile measured from single images with acquisition times of 100 and 50 ms.
(a) Scintillation light profile measured with the LS detector system along the depth of the beam and compared to ion chamber depth dose curve measurements (Advance Markus chamber perpendicular to the beam direction). (b) Lateral profiles taken at 2 cm depth with the LS detector system and compared to ion chamber measurements (Pinpoint ionization chamber). All measurements were averaged over an acquisition period of 100 MU.
Scintillation light profile measured with the LS detector system compared to depth dose measurement with an ion chamber and Monte Carlo simulations (all the curves were normalized at 2.0 cm).
Physical characteristics of the liquid scintillator BC-531 compared to the BC-400 plastic scintillator, polystyrene, and water.
