MP3 Phantom Tank
- Largest 3D water tank on the market with up to 600 mm detector moving range
- Includes a precision 3D stainless steel moving mechanism
- Includes three stepper motors for a detector positioning speed of 50 mm/s and a positioning accuracy of ± 0.1 mm
- Stable 20 mm thick acrylic walls and etched lines for precise tank alignment
The large MP3 water tank is suitable for very large field measurements. Beam incidence may be vertical, horizontal or oblique. The horizontal detector moving range is 600 mm x 500 mm and the vertical range is 407.5 mm. The 20 mm thick acrylic walls and bottom do not bulge during prolonged period of use and feature etched lines for precise tank alignment. Precision stepper motors are mounted close above the tank making it possible to adjust distances between the LINAC head and the water surface as small as 120 mm. They provide for high detector moving speed of 50 mm/s and high positioning accuracy of ± 0.1 mm. In contrast to analog drives, stepper motor drives do not require regular recalibrations. Stainless steel drive mechanics are used to minimize water perturbation and to preserve positioning accuracy during movement. They do not disturb or affect the measurement accuracy. The tank is supplied with a quick release coupling to connect the water reservoir T43163 easily. The delivery includes a cable connection box mounted to the tank, a spirit level and an ion chamber-adjusting device. To operate the tank, MEPHYSTO software and TBA electronics are required.
