A next generation all electric storage ring has been proposed by the Julich electric dipole investigation (JEDI) group to make a measurement of the proton's electric dipole moment with a statistical sensitivity of approximately 10−29ecm. Due to the large number of breakthrough and emerging technologies that would be needed for such an experiment, it has been suggested that a smaller scale prototype ring should first be developed. This smaller prototype will store protons at a different energy to the final experiment meaning the current polarimeter designed to monitor beam polarization would not be suitable.A polarimeter based on high voltage CMOS (HV-CMOS) and low gain avalanche diode (LGAD) is designed to effectively measure the polarization of protons in the range of 30-45 MeV. This polarimeter uses a split carbon foil fixed target and the asymmetry at 22-40◦ and 48-65◦ scattering angles is used to determine the polarization of the beam. A time of flight region is used to measure the energy of the scattered particles allowing selection cuts removing inelastic events to be made. Simulations to reinforce the polarimeter design are conducted to assist the design of the polarimeter for optimum performance and set limits upon detector dimensions such as sensor thickness.Measurements are made to characterise the sensor technologies proposed for this experiment and a test beam telescope is constructed for measurements of protons at the Birmingham MC40 facility. Results of proton measurements from a several layer LGAD system are presented.
