From Research to Market Leadership

It all started in 1989

1 January, 1989

AIT starts to develop Liquid Metal Ion Sources

AIT starts to develop Liquid Metal Ion Sources

At the Austrian Institute of Technology (AIT), the first Liquid Metal Ion Sources are developed, producing a precice beam of high energy Indium ions.

LOGION - Worlds first LMIS tested in microgravity


The 0.22 gram, solid needle is the first Liquid Metal Ion Source (LMIS) to be tested in microgravity.  This test consisted of 24 hour continious firing and resulted in....

10 June, 1991


The 1.2 gram LMIS was used for spacecraft charge potential control in a mass spectrometer for the Russian space station MIR. The Indium plasma beam is operated for a total of 120h between 1991 and 1994.

11 February, 1992


8 Indium emitter are being operated in space for a total of 600 hours of operation, as part of the GEOTAIL Mission.  These emitters primary function is for spacecraft potential control.

9 October, 1996


32 Indium Emitter are being launched as part of the CLUSTER Mission. After the launch failure, one instrument is being collected and the emitter are still functional!

19 August, 1998


8 Indium emitter are being operated in space for a total of 250h as part of the EQUATOR-S Mission

9 October, 2000


32 Indium emitter are being operated in space for a total of 6516h as part of the CLUSTER-II Mission

9 October, 2008

The Porous Tungsten Crown Emitter is being developed

The Porous Tungsten Crown Emitter is being developed

The development of the porous tungsten crown emitter marks the tipping point of the commercial success of the Field Emission Eelectric Propulsion (FEEP) technology. This emitter allows for high repeatability in a mass production of multi-emission site ion sources and is the basis of all current FEEP products of ENPULSION.

1 January, 2011


FOTEC buyes the department of Space Propulsion and Advanced Concepts from AIT and is inheriting all Know-How, People and Infrastructure related to FEEPs.


13 March, 2015


2 Indium emitter are being operated in space as part of the mass spectrometer that is investigationg the comet's surface.

1 February, 2016


32 Indium emitter are being operated on a cluster of four spacecrafts as part of the NASA MMS Mission

1 March, 2016

Foundation of ENPULSION

Foundation of ENPULSION

ENPULSION is being founded (first under the name of AMR Propulsion Innovations) as a Spin-Off from FOTEC to commercialize the FEEP technology.

Serial Production


ENPULSIONs production runs two Thruster per week

"Blue Canyon Technologies needed a compact and reliable solution for small satellite propulsion, and found the solution with Enpulsion. We have procured many thruster units to support a variety of spacecraft programs. The assemblies were delivered on time, and the technical support was excellent. We found that Enpulsion was an outstanding supplier, and we are looking forward to a long relationship with them."
