Location:  ISACII Conference Rm

Speaker:   Jürgen Duppich (Paul Scherrer Institute)

Title:     The first 1.5 years of clinical operation of the SC cyclotron and the beam lines at PSI - From a parasitic user to a stand-alone facility.

Abstract: The new proton therapy system PROSCAN at Paul Scherrer Institute started to treat patients in February 2007 at the existing Gantry-1, with beams from the world's first 250 MeV super-conducting cyclotron (ACCEL/Varian) for proton therapy. A second new Gantry-2, a new area for eye treatments (OPTIS2) and an area for experiments have been connected. The eye treatment line is being prepared for patient treatments, due to start this year and at Grantry-2 the commissioning of 3D beam scanning started. A continuous patient operation with no shut down longer than three days has been performed. The number of treatments per day has been ramped up steadily until about 15 patients in a continuous 5 days/week treatment program have been reached. For the  cyclotron and beam lines a very good availability of 97.79% has been obtained during the planned machine operation hours.
