National Physical Laboratory

The National Physical Laboratory is the National Metrology Institute (NMI) of the United Kingdom which has the most experience worldwide in light-ion beam dosimetry. NPL has a strategic interest in light-ion beam dosimetry given the metrology support requested by the proton-therapy community within the UK. NPL’s experience in the field of light-ion beam dosimetry includes the development of dedicated graphite calorimeters, the characterization of ionization chambers and other dosimeters, such as alanine, the development of dedicated phantom materials and the use of Monte Carlo simulations in support of developing dosimetric capabilities
