Because of the compact structure, the magnetic field in the extraction area is complex and there is no room for the focusing elements, the methods to control beam envelope in extraction area are needed. In this paper, the influence of envelope caused by the angle between the foil and the beam has been studied, the experiment on a 14 MeV compact cyclotron that construct in CIAE (China Institute of Atomic Energy) has been done, the result is well agrees with the theoretic design. For the small medical cyclotrons, this method can be used to adjust the beam spot on the liquid target which installs on the exit of the cyclotron.
