The antiproton program at FAIR requires a dedicated proton linac to be used as injector for the SIS 100 synchroton. This 325 MHz linac will accelerate up to 70 mA proton beam to the injection energy of 70 MeV. This linac will be the first machine based on CH-DTL's, the novel cavity developt by Frankfurt University and GSI. This new cavity is characterized by the lack of internal focusing elements which allows the construction of very compact cavities resulting in a higher shunt impedance when compared to conventional RF structure. The proton linac is based on 6 coupled CH-DTL followed by three standard CH's for a total length of around 25 meters. A complete description of the beam dynamics together with the general status of the project is presented and discussed,
