ISOTRACE cyclotrons

ISOTRACE cyclotrons are generating a 80 µA / 12 MeV beam which is used to manufacture isotopes, key elements of tracers for biomolecular imaging.

Their specific design makes them easy to install and operate in restricted environment such as hospitals.

Thermodynamic solar power plants

The ALSOLEN company develops medium power thermodynamic solar power plants (up to 20 MWe) using the technology of Fresnel mirrors. These power plants called ALSOLEN use oil as heat-transfer fluid. This oil is heated at 300°Celsius and transfers its thermal energy to an Organic Rankine Cycle (ORC), which generates electricity via a turbine.

High definition cameras
and mega-pixels

These compact video cameras are endowed with rugged simplified structures offering a quality of image far above CCIR standards. Designed with an architecture including a single small size board (HEMERA HD, supporting sensor types from 1/6" to 2/3") up to three boards (HEMERA MEGA with 11 MPx sensor), they incorporate on-board software to improve image quality, such as contrast improvement and noise reduction. They are used in all scientific, industrial, safety and military applications when observing details in real time become important.

Airspeed sensor

AER with the technical support of ONERA has developed a new probe measuring a pressure on a winglet profile. Particles, due to their mass and relative speed, are ejected away from the probe and do not have any tendency to enter into the pressure measurement holes. Many solutions have been analyzed and tested in ONERA wind tunnels. Prototypes have been successfully tested on the ground and in-flight. The AER probe offers a strong signal giving accurate and valid information regardless of the flight conditions (high altitude, very severe icing conditions, heavy rain, etc.)

Propellant valves

AER has a range of flow-control valves for satellite propellant subassemblies.

These sturdily designed and tested valves are Flight Proven. The present range covers requirements for engines with a thrust of 1 to 500N, in mono-propellant or bi-propellant. They are used in apogee boost motors on geostationary satellites (telecoms), in propulsion for small low-orbit satellites for altitude control and for specific space applications.

Lithium-ion
cells ans battery systems

The system architecture is completely designed by PROLLiON:

  • use of existing PROLLiON cells or development of specific ones
  • mechanical, thermal, electronic and electrotechnical system architecture
  • specifically designed energy management (SOC, SOE, SOP, SOH), protection and communication functions
  • modularity: parallel and series configuration of modules and battery packs

ALCEN believes that inside control over technologies is an essential element for maintaining an enduring innovation policy.

As a result, unlike  to normal trends, it has decided to integrate itself into numerous different laboratories working on a wide range of subjects.

Even so, it is open to cooperation with outside research centers.

With the wide range of knowledge acquired in this way, it can lay claim to being an innovative designer even in complex products and systems that incorporate various functions.

ALCEN works in four domains: defence & security, energy, medical and aeronautics.

Its ambition is to establish a constant innovation policy in these domains, primarily applied to its own products and services.

Wherever possible, they offer innovative solutions.

It organizes its teams in structures that are both independent and coordinated, set up around top-level, fully accountable members of staff.
