| MOPL004 | Beam Dynamics Simulations and Code Comparison for a New CW RFQ Design | 188 |
|
||
|
Research and development of CW applications is an important step in RFQ design. The RF potential should be limited by 1.3-1.5 of Kilpatrick criterion for the CW mode. A 2 MeV RFQ is under development for the compact CW research proton accelerator, as well as for planned driver linac* in Russia. The maximum beam current is fixed to10 mA; the operating frequency has been set to 162 MHz. The new RFQ linac design will be presented and beam dynamics simulation results will be discussed. Calculations of beam dynamics are provided using the codes BEAMDULAC (developed at MEPhI for linac design) and DYNAMION. A comparison of the software performance is presented.

| TUAM7Y11 | High Current Uranium Beam Measurements at GSI-UNILAC for FAIR | 319 |
|
||
| In the context of an advanced machine investigation program supporting the ongoing UNILAC (Universal Linear Accelerator) upgrade program, a new uranium beam intensity record (10 emA, U29+) at very high beam brilliance was achieved last year in a machine experiment campaign at GSI. The UNILAC as well as the heavy ion synchrotron SIS18 will serve as a high current heavy ion injector for the new FAIR (Facility for Antiproton and Ion Research) synchrotron SIS100. Results of the accomplished high current uranium beam measurements applying a newly developed pulsed hydrogen gas stripper (at 1.4'MeV/u) will be presented. The paper will focus on the evaluation and analysis of the measured beam brilliance and further implications to fulfil the FAIR heavy ion high intensity beam requirements. | ||

| THPM9Y01 | An Advanced Procedure for Longitudinal Beam Matching for SC CW Heavy Ion Linac With Variable Output Energy | 571 |
|
||
| A multi-stage programm for the developmnet of a heavy ion superconducting (SC) continuous wave (CW) linac is in progress at HIM (Mainz, Germany), GSI (Darmstadt, Germany) and IAP (Frankfurt, Germany). The main beam acceleration is provided by up to nine multi-gap CH cavities. Due to variable beam energy, which coud be provided by each cavity separate, a longitudinal beam matching to each cavity is extremely important. The linac should provide the beam for physics experiments, smothly varying the output particle energy from 3.5 to 7.3 MeV/u, simultaneously keeping high beam quality. A dedicated algorythm for such a complicate matching, providing for the optimum machine settings (voltage and rf phase for each cavity), has been developed. The description of method and the obtained reasuts are discussed in this paper. | ||
