1.1 Perspex Tank
The moving mechanism as well as several ancillary
devices (refer to section 2) are attached to the Per-
spex tank. The tank (Figure 4) is filled with water. The
water level should remain approx. 20 mm below the
top edge of the tank. Horizontal and vertical lines on
the tank allow it to be easily leveled. As an alternative,
you can use the circular bubble level that is part of the
MP3-PL accessories.
Additional marks at the bottom and on the walls of the
tank allow it to be aligned, using the accelerator laser
system.
The Perspex plates are glued together. On the inside
of the tank, a special sealing agent protects the glue
from penetrating water.

1.2 Moving Mechanism
CAUTION
Improper handling.
Risk of injury!
Do not reach into the Perspex tank while the
moving mechanism is working.
Pay attention that hairs or cloths of the user and
other persons involved do not touch the rotating
spindle.
The moving mechanism is made of stainless steel
and is permanently installed on the tank. It consists
of three arms with the following designations:
A = horizontal arm, fixed,
B = moving vertical arm and
C = moving horizontal arm with slider.
The moving mechanism is suitable for both horizon-
tal and vertical radiation. Holding devices for detec-
tors to move in the field are screwed to the slider of
the C-arm. The slider and the arms are moved by
stepper motors that permit a minimum step width of
0.1 mm. The reproducibility of the geometric posi-
tioning is also ± 0.1 mm.
The moving range limits can be adjusted for each
axis and stored in the control unit to ensure that the
detector does not hit the Perspex walls.
The components of the moving mechanism, particu-
larly the guides and moving parts, are not adversely
affected by water. Bending or contortion due to
water absorption or corrosion are thus excluded.

1.3 Positioning Device
The positioning device allows the Perspex tank to
be aligned, using the laser system of the accelera-
tor and the lines on the walls of the tank.
The positioning device has three adjustable legs
that allow the height to be adjusted by ± 10 mm.
Additionally, the three adjusting screws allow the
tank to be adjusted horizontally by ± 10 mm, or by
approx. 1° on a vertical axis (micro-adjustment). A
mechanism allows the tank to be rotated by
45°or 90° (refer to Figure 6 for center of rotation).
Horizontal alignment of the tank is easy when it is
filled to the horizontal lines and the water surface is
used as a level.

Reservoir
CAUTION
Improper handling.
Equipment damage!
If you are pumping water, you must not remove
the plastic hose between SCANLIFT and Per-
spex tank.
The positioning device is screwed together with the
chamber cable holding device and the Perspex tank
to the triangle holder of SCANLIFT (refer also to
section 2). For mounting and handling of SCANLIFT
please refer to the user manual of SCANLIFT.
1.5 Control Unit and Control
Pendant
The MP3-PL system is operated via the control unit
and the control pendant.
The control unit (TBA CONTROL UNIT ) is an
interface that connects the MP3-PL water phantom
to the computer. It supplies the power for the step-
per motors and controls the detector movement.
The control pendant (TBA CONTROL PENDANT)
can be connected either to the control unit or to the
junction box (at the Perspex tank). The control pen-
dant indicates the detector coordinates A, B and C
and allows the detector to be moved at two different
speeds (10 mm/s and 50 mm/s). Additionally, the
limits for the detector movement, the null point in
the central beam and the reference points can be
determined via the control pendant. Please note
that some of the control pendant functions are
available only when it is directly connected to the
junction box at the Perspex tank (refer to the user
manual of the control unit and the control pendant).
Therefore it is recommended to connect the control
pendant to the junction box.
NOTE
During adjustment work with the TBA CONTROL
PENDANT the TBA CONTROL UNIT can be
disturbed by a simultaneous communication
between the control unit and the COM-Server
via the RS232 interface or
with the control unit via the COM-Server via
the TCP/IP interface.
Disturbances are for instance that determining
the limits or switching the speed from FAST to
SLOW is not functioning properly.
In order to avoid disturbances during adjustment
work you have to disconnect the RS232 connec-
tion or the TCP/IP connection to the COM-
Server.
