Abstract
This paper presents a method for characterizing electric field profiles of radio frequency rf quadrupole ion trap structures using sensors based on slab coupled opticalfiber sensor SCOS technology The alldielectric and virtually optical fibersized SCOS fits within the compact environment required for ion traps and is able to distinguish electric field orientation and amplitude with minimal perturbation Measurement of the fields offers insight into the functionality of traps which may not be obtainable solely by performing simulations The SCOS accurately mapped the wellknown field profiles within a commercially available threedimensional quadrupole ion trap Paul trap The results of this test allowed the SCOS to map the more complicated fields within the coaxial ion trap with a high degree of confidence as to the accuracy of the measurement
