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 [[proton]] to [[Uranium]] with energies up to 11.4 [[MeV]] / [[atomic mass unit | u]].

The main branch consists of two ions sources terminals followed by a [[Radio Frequency Quadrupole (RFQ)]] and and by an Intergidigital linac [[IH linac accelerator]] resonating at 36 MHz up to the energy of 1.4 MeV/u. The main part then is operated by a classical [[linac]] of the Alvarez type which resonates at 108 MHz. Final energy adjustmnet can be performed in the last section which consists of a series of single gap resonators. This solutions was proposed in order to achieve the 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.
