	Ion Source Hydrogen Positive (ISHP) is a 2.7 GHz microwave discharge installed at ESS Bilbao in Spain. This source will be employed in future application of high proton current in the field of research projects and for industrial processes. ISHP produces over 30 mA of pulsed proton beam by operating at 2.7 GHz. The magnetic field is produced by two independently movable coil pair and the extraction system is composed of a plasma electrode at high voltage platform potential, two ground electrodes, and a negatively biased screening electrode inserted between the ground electrodes. The last three electrodes are contained in the extraction column, and can be moved as a group by stepper motors, to change the distance between the plasma electrode and first ground electrode. Measurements with different extraction system setups will be described to show the improvement of the beam intensity and beam emittance.
