The Cen­tro Nazionale di Adroter­apia On­co­log­i­ca (CNAO) is the Ital­ian cen­tre for deep hadron­ther­a­py, name­ly an in­no­va­tive type of ra­dio­ther­a­py using hadrons. The wide range of beam pa­ram­e­ters (i.e., en­er­gy and in­ten­si­ty) at pa­tient level to­geth­er with the ad­van­tages of hadron-ther­a­py with re­spect to tra­di­tion­al ra­dio-ther­a­py nour­ish­es the hopes for more ef­fec­tive pa­tient re­cov­ery. After the LEBT and the RFQ com­mis­sion­ing, the IH com­mis­sion­ing is now in progress. First pa­tients are ex­pect­ed to be treat­ed in 2010. The pre­sent paper sum­ma­rizes and eval­u­ates the Low En­er­gy Beam Trans­fer (LEBT) line com­mis­sion­ing, which has been car­ried out be­tween July 2008 and Jan­uary 2009.
