HITRAP is an RTD network of European research teams. It started on November 1st, 2001 and is scheduled for four years. The goal of the network is the development of novel instrumentation for a broad spectrum of physics experiments with heavy Highly Charged heavy Ions (HCI) up to bare uranium (U⁹²⁺) at low energies (<1 eV/u) which can presently not be performed at any other institution using light or medium-heavy HCI or heavy HCI at MeV energies.
In the planned GSI future facility , HITRAP is an essential part of the SPARC and FLAIR collaborations.

The HITRAP RTD network is closely related to the European RTD networks NIPNET and IONCATCHER.

The three networks have a common Mission Statement:

Ion and atom traps have become spectacular tools for precision measurements. Three European RTDs, IONCATCHER, NIPNET and HITRAP, have as common mission to make the trapping techniques available at the large accelerator facilities of Europe. This will allow important questions to be answered related to fundamental interactions and the determination of fundamental constants. Examples are the search for deviations from the Standard Model in the electroweak interaction and the determination of the electron mass, respectively. This research requires the production and trapping of rare ions and atoms, using Europe's large-scale accelerator facilities. They are either heavy elements with all or nearly all electrons removed (HITRAP), or short-lived nuclides produced in nuclear reactions (NIPNET). The use of accelerators implies rapidly moving ions, which require deceleration and stopping before trapping can take place, to make this process effective is the task of IONCATCHER. The common aims and efforts have lead to an agreement between the three collaborations to have joint collaboration meetings to effectively share knowledge and know-how. In addition they aim for a common education of the group members, in particular the graduate students.

The research objectives of HITRAP include the development of novel instrumentation and prototypes:

• Linear decelerator for deceleration of HCI from high energies (few MeV/u) down to rest
• Cooler Penning trap for capturing, cooling and accumulation of HCI at low energies (< eV/u)
• Experimental set-ups and detectors for investigation of the interaction of low-energy HCI with photons, atoms, molecules, clusters, surfaces, microstructures and solids
