Design of Hydrogen Ion Concentration Measurement System
This paper presents an application for measuring the concentration of hydrogen ion by using ion selective electrodes. By this research we hope to provide useful information and verify the feasibility of measuring the concentration of other ions in the same way for sensing sweat. In this research, a pH electrode is used to generate an electrical potential which reflects the concentration of hydr...

Blocking: Reduction of detector signal rate when aligned with a crystal axis or plane. Channeling: Guided trajectory of incident ions between crystal axes or planes. Collision cascade: Series of atom-atom collisions initiated by an ion-atom collision. Cross section: Effective area presented by each atom or nucleus for a specific type of interaction with an incoming ion. lmplantation: Addition o...
متن کاملMulti-mev Ion Beams from Terawatt Laser Thin-foil Interactions
We have conducted investigations of a collimated beam of fast protons, produced by a 10TW laser with frequencies of either ω0 (corresponding to 1.053 micron light) or 2ω0 (corresponding to 532 nm light) focused to an intensity of more the 3x10 W/cm onto the surface of a thin-film target. Energies as high as 10 MeV and total number of 10, confined in a cone angle of 40°±10° have been observed. T...
متن کاملEffective Point of Measurement in Cylindrical Ion Chamber for Megavoltage Photon Beams
Introduction For dose measurement in Megavoltage (MV) photon beams with ion chambers, the effect of volume occupied by the air cavity is not negligible. Therefore, the result of measurement should be corrected with a displacement perturbation correction factor (Pdis) or using an effective point of measurement (EPOM). The aim of this study is to calculate the EPOM for cylindrical ion chamber and...
متن کاملMeasurement of MeV Ion Track Structure in an Organic Solid.
Ion tracks, formed by the interaction of energetic charged particles with matter, have played an important role in the development of modern physics. More recently, MeV-GeV ion track production has been used to modify materials in a controlled manner [1,2], being a potential tool to engineer material properties in the nanometer to micrometer scale. MeV-GeV ions are finding recently wider use in...
