Positive impulse $(1.2/50 \mu s)$ breakdown voltage measurements were carried out in carbon dioxide $(CO_2)$ under different electric field conditions by varying the sphere diameter in sphere-plane geometry. $CO_2$ gas pressures up to 1 MPa were used, with the gap distances varying between 5 and 20 mm. It was observed that there exists a critical field (corresponding to the sphere diameter of 20 mm) at which the breakdown voltage is a maximum over the entire range of pressures investigated. This phenomenon is similar to the corona stabilization effect and could be due to presence of negative ion space charge.
