5.2 Experiment chamber (
1
)
The experiment chamber (Fig. 4) includes the following func-
tional elements:
5.2.1 Sliding door (A)
Made of lead-containing acrylic glass. The door is perma-
nently monitored by a safety circuit and it is either locked or
released via an actuator.
For monitoring the position of the sliding door (open/closed),
two independent encoders are connected to the central
safety unit of the XR 4.0 X-ray expert unit. If the sliding door
is closed and the unit is in a safe state, the operator can lock
the sliding door via the control panel. The position of the ac-
tuator for this purpose is monitored by two additional inde-
pendent encoders that are also connected to the central
safety unit.
In order to open the sliding door,push it first against the stop
on the right-hand side.The S-Lock is now unlocked and the
door can be opened.
X-rays can only be generated when the door is locked.
5.2.2 X-ray outlet (B)
The X-ray outlet is located on the left-hand side of the ex-
periment chamber. It is used to hold metal tubes with circular
double-apertures for generating a beam of rays that is suited
to the experiment in question.
5.2.3 Socket panel in the experiment chamber (C)
Socket panel for the connection of devices that are located
inside the experiment chamber, e.g. a goniometer. The sock-
ets connect the devices either with the X-ray unit itself or they
lead to the external socket panel that is located on the right-
hand side of the unit (looping-through). This enables, for ex-
ample, the control or read-out from the outside of a digital
camera that is located inside the experiment chamber.
5.2.4 Working channel (D)
The working channel is located on the back wall of the ex-
periment chamber, at the bottom on the right-hand side. It
ends on the right-hand side outside of the unit and, thereby,
forms a connection through which, for example, a contrast
medium can be fed into the experiment chamber through
hoses during the operation of the unit. The shape and cross-
section of the working channel ensure that no X-radiation can
escape.
5.2.5 Optical bench (E)
An optical bench is fastened to the bottom of the experiment
chamber along the optical axis of the X-rays. The adapters
that are required for the experiments can be attached to, and
shifted on, this optical bench.
5.2.6 Temperature monitoring system
The temperature of the air inside the experiment chamber is
monitored and controlled via a fan system.
5.2.7 Interior lighting
The linear LED lighting for illuminating the experiment cham-
ber can be activated as required.
5.2.8 Holder for the goniometer
The goniometer 09057-10 is magnetically secured inside the
experiment chamber via magnetic foil and has an electrical
connection to the XR 4.0 X-ray expert unit (plug & measure).
5.3 Control panel at the front of the unit (
2
)
The control panel at the front of the unit is shown in Fig. 5
and described in Table 1.
5.4 Tray for accessories (
3
)
The lower part of the XR 4.0 X-ray expert unit includes a tray
with moulds for the following components (for example):
Geiger-Müller counter tube
X-ray
energy
detector
Diaphragms
