Pre-clinical evaluation of a drug candidate’s risk of inducing psychiatric adverse side effects in patients
The ALCEN Group has developed an extensive expertise and understanding of RNA editing, a key epigenetic mechanism involved in a large number of pathologies.

Development, Manufacturing & Maintenance of Heat Exchanger-Reactors with high levels of thermal and safety performances
The ALCEN Group provides disruptive Heat Exchangers-Reactors (HERs) based on the mastering of the Hot Isostatic Pressing (HIP) assembly process.
This compact Heat Exchanger-Reactor with superior performance is equipped with at least two series of interlocking channels:
A first series of channels is the site of the chemical reaction. Depending on the reaction, this series of channels can be functionalized by integrating the catalyst;
A second series of channels extremely close to the first series of channels, but with the same mechanical strength and sealing guarantees, is used to circulate the thermal control fluid.
It provides optimal mechanical strength, coupled with an excellent thermal performance, regardless of whether the reaction is highly exothermic or endothermic.
Alcen has the capacity to perform:
Design & testing of HERs for highly thermal demanding chemical reactions, for either the energy or chemistry sectors
Reverse Engineering of old chemical reactors to propose high-performance solutions
Material knowledge to reach the best solution according to the use, either for handling thermo-mechanical constraints or for chemical neutrality constraints
Functionalization of the HER by depositing a catalyst within reactive channels to increase the kinetics of the reaction. This functionalization is mastered to improve the developed surface of the catalyst as well as to improve the reactant mass flow through each individual reactive channel
Designing and manufacturing of adapted thermal insulation according to the operating temperature and power consumption budget
Commissioning and decommissioning of the HER
AI performance management
On-site maintenance and off-site retrofit according to the performance target (MTBF, MTTF…)
Life-cycle management of the HER to be environmentally responsable
Some examples of applications include
This new Heat Exchanger-Reactor is a real «game-changer» in fighting CO2 fossil fuel emissions as well as in going from batch chemistry to continuous intensified green chemistry. The infinite modularity provided by the Heat Exchanger-Reactor is a major asset in reaching the large production capacities targeted, with total flexibility. The Heat Exchanger-Reactors can be adapted directly to an existing process or can equip an installation ex nihilo.
When used in the Energy sector, the HER allows for CO2 to be recycled into synthetic molecules such as methane, methanol or kerosene as well as allowing for the synthesis of green hydrogen.

RF Component Designing, Scaling and Manufacturing
The ALCEN group has historical expertise in the design, manufacturing and assembly of radio-frequency components used in various applications. This know-how allows the group to work on new designs as well as existing ones:
For new designs: RF scaling with HFSS (high frequency structure simulator) software, Thermal simulation including the choice of material involved, prototyping (low- and high-level RF testing) and manufacturing
For adaptive designs: adapt an existing design to manufacturing constraints while maintaining RF performance and improving performance by redesign
Due to its mastery of RF component designing, scaling and manufacturing, the ALCEN group manufactures components for beamlines and high-power RF couplers for large scientific instruments.
Some examples of applications include
Accelerating Waveguides
Designing and manufacturing a range of S to X band accelerating waveguides using different modes. They accelerate electrons generated by the gun, via the injected RF field.
The entire manufacturing process takes place internally due to a strong vertical integration (machining, brazing, RF tuning, TIG and laser welding, leak tests).
The RF calculations and thermal and dynamic beam simulations are also done in-house.
This is used for a wide range of different types of Linac.
Radio-Frequency Window
ALCEN controls all of the manufacturing stages, from design to final testing.
RF windows allow the RF power to pass from the source to the RF device (accelerator waveguide, antenna, etc.) while isolating the ultra-high vacuum area from the SF6 atmosphere. The isolation is done via ceramic brazed in a metallic part.
For higher powers, a layer of TiN is deposited on the blank side of the ceramic to avoid the effects of multipactoring.

Radiofrequency coupler
