Description

Our developments on production of 165Er and 52Mn [1] for bimodal sensor MRI/PET or SPECT turn to be necessary an automatisation of separation process especially in case of 52Mn in terms of radiation protection. For that, a homemade system has been developed for purification of radiometal target especially for separation step with homemade software, ACCRA to remote control all operations. The system has 22 input-output switches controlled by Siemens automate in state 0 or 1. Then radiochemist define application for each switch, create a sketch in a paint file, and create a word file to coordinate real command of switch with its position on sketch. Finally, he creates a second word file to define for all step state of switch. Easy use and versatility of ACCRA has been demonstrated [2]. Nevertheless, repeatability was not satisfactory [3]. An evolution of system with introduction of more sensors and actuators on line is necessary to develop.
