Commissioning of Ih-rfq and Ih-dtl for the Gsi High Current Linac

چکیده
The new 1.4 MeV/u front end HSI (HochStromInjektor) of the Unilac accelerates ions with A/q ratios of up to 65 and with beam intensities in emA of up to 0.25 A/q. The maximum beam pulse power is up to 1300 kW. During the stepwise linac commissioning from April to September 1999 the beam behind of each cavity was analysed within two weeks. A very stable Ar beam out of a volume plasma source MUCIS was used mainly. The measured norm. 80 % emittance areas around 0.45 π mm mrad are close to the results from beam simulations. Up to 80 % of the design intensity at the linac exit were achieved. In February 2000 an U beam from the MEVVA source was accelerated for the first time.

The Italian hadron-therapy centre CNAO (Centro Nazionale di Adroterapia Oncologica) [1] is designed for the treatment of tumours with proton and light ion beams and to clinical and radiobiological research. The design consists of two ECR ion sources, a 7 MeV/u injector linac identical to the linac of the Heidelberg ion therapy centre HIT [2][3] and a 400 MeV/u synchrotron. GSI delivers technica...
متن کاملThe Low Energy Beam Transport System of the New GSI High Current Injector
The UNILAC was improved for high current performance by replacing the Wideröe prestripper accelerator by an RFQ and an IH-type DTL. In addition, one of two ion source terminals was equipped with high current sources of MUCISand MEVVA-type. Therefore, a redesign of the LEBT from the ion source to the RFQ entrance was necessary. The new LEBT was installed at the beginning of 1999. The commissioni...
متن کاملCOMMISSIONING OF THE 1.4 MeV/u HIGH CURRENT HEAVY ION LINAC AT GSI
The disassembly of the Unilac prestripper linac of the Wideröe type took place at the beginning of 1999. An increase of more than two orders of magnitude in particle number for the most heavy elements in the SIS had to be gained. Since that time the new High Current Injector (HSI) consisting of H-type RFQ and DTLstructures for dual beam operation was installed and successfully commissioned. The...
