The '''Uni'''versal '''L'''inear '''Ac'''celerator is a [[heavy ion]] [[linear particle accelerator | linac]] based at the Heavy Ion Research Centre ([[Gesellschaft für Schwerionenforschung|'''GSI''']]) near [[Darmstadt]], [[Germany]]. It can provide beams of accelerated [[ion]]s of elements from [[Carbon]] to [[Uranium]] with energies up to 20 [[MeV]] / [[atomic mass unit | u]]. The UNILAC is used both to send beams of heavy ions to experiments and to load the '''SIS''' Heavy-Ion Synchrotron (Schwer-Ionen-Synchrotron) with high-energy ions.

Collisions between heavy-ion beams and stationary targets can be made to generate superheavy [[transactinides | transactinide elements]].

Experiments using beams from UNILAC have produced, in the past 20 years, elements [[unnilseptium|107]] to [[ununbium|112]].

The main branch consists of two ion source terminals followed by a [[Radio Frequency Quadrupole]] and by an Interdigital linac [[IH linac accelerator]] resonating at 36&nbsp;MHz up to the energy of 1.4&nbsp;MeV/Da. The main part then is operated by a classical [[linac]] of the Alvarez type which resonates at 108&nbsp;MHz. Final energy adjustment can be performed in the last section consisting of a series of single-gap resonators. This solution was proposed for maximum flexibility in beam energy.

The UNILAC is used both to send beams of heavy ions to experiments and to load the [[SIS18]] Heavy-Ion Synchrotron (Schwer-Ionen-Synchrotron) with high-energy ions.

poooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo bum willy nose

Experiments using beams from UNILAC have produced, in the past 20 years, have produced elements [[unnilseptiumBohrium|107]] to [[ununbiumCopernicium|112]].
