TABLE OF TANDEM-PIAVE-ALPI REPRESENTATIVE BEAMS
A. The table assumes:
- a terminal voltage of 14 MV of the XTU-Tandem;
- the maximum available accelerating field of medium and high beta sections of ALPI at their power dissipation reference value (7 W per cavity)
- 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 (email@example.com) 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:
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;
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.
