Please, click here to see the table!


Please note:
A. The table assumes:  

  1. a terminal voltage of 14 MV of the XTU-Tandem;
  2. the maximum available accelerating field of medium and high beta sections of ALPI at their power dissipation reference value (7 W per cavity)
  3. Intensity limitations may derive from radiation protection requirements, Tandem stripper lifetime and maximum current through the superconducting RFQs.

B.  Values obtained with 2 stripping foils are underlined.

C.  The isotopes that requires enriched source target materials are marked with (*) Users who select a beam marked with (**) are kindly advised to contact the Accelerator Division ( for technical information before submitting a proposal with this beam.

D.  In each reported case, lower-than-maximum energies do not imply higher currents on target.

E.  Possible accelerator configurations are:  T-A (Tandem or Tandem-ALPI), T-A with low b (Tandem-ALPI including ALPI low beta section), P-A (PIAVE-ALPI).


Values updated in January 2020.
Please consider the following:

  1. With respect to the previously published table, the accelerating field of the resonators - on which the attainable energies are based - are more realistic and trustworthy;

  2. The values are based on a maximum available Tandem voltage of 14 MV instead of the previous 14,5 MV, with some conservatism due to the recent profound maintenance on this accelerator.
