A new heavy ion superconducting linac at
TRIUMF is being installed to boost the final
energy of radioactive beams from ISAC from
1.5MeV/u to above the Coulomb barrier. A
first stage of 20MV consisting of five medium beta cryomodules each with four quarter wave bulk niobium cavities
and a superconducting solenoid is being commissioned in early 2006. The cavities (Beta0=0.057, 0.071) operate cw
at 106MHz with design peak fields of Ep=30MV/m, Bp=60mT while delivering an accelerating voltage of 1.08MV at
∼4W power consumption. The report will summarize the commissioning results and early operating experience.

The new Spiral 2 facility will deliver high intensity
rare isotope beams for fundamental
research in nuclear physics, and high neutron
flux for multidisciplinary applications.
Based into the ISOL and in-flight isotope production methods this facility will cover broad areas of the nuclide chart.
The driver accelerator must deliver CW beams of deuterons (40 MeV, 5 mA) and heavy ions (q/A=1/3, 15 MeV/
A, 1 mA). The injector is composed of two ion sources (deuterons and heavy ions) and a common RFQ cavity (88
MHz). The Superconducting Linac is composed of two sections of Quarter Wave Resonators (beta 0.07 and 0.12,
frequency 88 MHz) with room temperature focusing devices. After two years of preliminary study, and following the
recent decision to launch the construction phase, a complete design of the Driver Accelerator is presently completed.
Important results have been obtained during the initial R&D phase, in particular on ion sources, RFQ and superconducting
resonators prototypes. Status report on both the design and the prototype performances will be given in this
contribution.
First Stage of a 40MeV Proton Deuteron Accelerator Commissioning Results
In 2006 the first stage of a 40MeV super-
C. Piel, K. Dunkel, M. Pekeler, H. Vogel, P. vom Stein (ACCEL) conducting linear accelerator for protons and
deuterons will be commissioned at SOREQ.
This paper will present commissioning of the ECR source after final assembly. First results of the 1.5MeV/u cw RFQ
are expected, further test results of the beta=0.09 half wave superconducting resonators are presented, and resonator
geometry improvements with respect to electron multipacting behaviour will be discussed. An outlook on the project
with respect to achieve the final energy of 40MeV will be given.
