1. A monitoring system is under discussion with BI. The details will be finalised in the future and reported back.

2. As a follow up of the previous vacuum studies, the option of installing a NEG pump beneath the dummy septum has been considered. This option would provide enough pumping capacity and would be easy to implement. The cost is of 12kCHF. It is decided to foreseen a vacuum flange in the tank design in order to enable installing the pump in case of need. The dose delivered to the pump will be estimated. It is stressed that the device should undergo vacuum acceptance tests prior to installation.

3. Studies of shadowing have been launched

   • the reduction of radiation field and the resulting activation associated with MTE operation by a factor of 5-10 in the whole environment of SMH16 Concerning the shielding.

   • Radiation field and resulting activation associated with future MTE operation lower by a factor of 3 than present CT operation in the whole environment of SMH16.

   • The studies will be pursued to refine the figures and optimise the scheme. Furthermore, tracking in the rest of the PS circumference will be performed to detect possible hot spots.
