In collaboration of GSI, HIM and Goethe University Frankfurt new designs for the CH-GTL cavities of the proposed Helmholtz Linear Accelerator (HELIAC) are developed. The cw-mode operated linac is intended for various experiments, especially with heavy ions at energies near the coulomb barrier for super-heavy element research. Currently eleven cavities are considered which will be split into four different cryostats. Each cavity will be equipped with dynamic bellow tuners. More detailed designs the cavities CH 3 and CH 4 more are given and compared to the specifications of the given beam dynamics. A closer look of the strain of the bellow tuners under mechanical stress is done, the behaviour of multipacting is investigated and the geometry of the cavities is so optimized that the peakfields are minimized.
