Answers for life.

SILAC®
Siemens Industrial Linear Accelerator
The SILAC® Linear Accelerator System is designed for
special Non Destructive Testing (NDT) applications and for
usage in scanning devices for cargo and vehicles in the
security sector.
Stationary and mobile types are available with a variable
set of energies in the range of 1 to 9 MeV photon radiation.
The SILAC® System is a compact module, which includes
all necessary components like linear accelerator, shielding,
magnetron, high frequency modulator, power supplies,
interfaces.
Additional and optional components such as external
supplies for hot and cold environment, or a collimator, are
available.
General information
The system can be equipped with 2 types of linear accelerator
for a wide energy range (6 MeV, 9 MeV maximum
Energy). The actual energy level can be varied by means
of software.
The energy is defined by the maximum electron energy of
the selected mode and generates a spectrum of photons
according to the corresponding Bremsstrahlung.
The modular design allows customized installations in a
stationary environment in bunkers or control areas as well
as mobile setups on trucks and non-stationary equipment.

Three main components are combined in one module
design:
◾ An accelerator section
◾ An HF-generation section
◾ A control and interface section
On request, it’s possible to include collimators or additional
low leakage shielding.
Control of the entire system is possible by an external
user interface. This system software can be operated on
any standard Windows-computer or by SPS system on
customer site.
It is possible to vary many parameters at the software
control console like electron energy, pulse width, repetition
rate or beam current.
The integrated sensors for temperature, dose rate or
water flow and the predefined software and mode tables
supervise the status of the system at all times and produce
warning messages or trigger system interlocks to avoid
hazardous situations.

Technical data
A. Power parameter
The system is equipped with a linear electron accelerator,
which accelerates through 3 GHz radiofrequency standing
waves until the maximum electron energy from 1 to 9 MeV
is reached, depending on the type of accelerator (other
energies on request) (Figure 1).
B. Cone beam 6 MeV
The following dose values characterize the beam angle:
15°: Dose ~ 50 % of center beam line
45°: Dose ~ 9 % of center beam line
C. Image quality
Distinguishable wire diameter and distance of the
double-wire penetrameter Phantom 5D are 320 µm,
which corresponds to an image blur of 640 µm
(Figure 2).

ASTM E1742-00:
The following unit mold is placed between 2 plates made
on 80 mm thick steel (Figure 3).
The diagram shows the result which is generated with the
6 MeV SILAC® (Diagram 1).
D. System interface
Control of the whole system is possible via an external
user interface. This system software can be operated on a
standard Windows computer at the customer site or by
SPS System (24V TTL).
All relevant parameters like energy, dose, repetition rate
or pulse length are variable within the system limits.
In order to start the beam pulse the user can choose
between external triggering and internal trigger control.
The system control is fully integrated and shows the
user all status messages regarding time stamps, status of
system and safety loops and system errors (Figure 4).
E. Safety circuits
The “beam off“ safety switch is realized by an emergency
stop switch of cat. 4, which has to be lined in the radiation
safety loop at the user site.
The system has an interlock system. When activated
the errors are shown on the user monitor and the affected
components stop operation.
After solving the problem, the beam operation can be
continued.

F. Mechanical design
The main design elements are made of aluminum
or stainless steel.
The standard configuration can be operated in the
horizontal position only.
Cooling system
The system needs a DI water supply. This can be provided
at the user end or by the supplier. The recommended
indoor cooling system has the following dimensions:
Width 480 mm, length 510 mm, height 560 mm
