A 50 cm wide by 41 cm tall, 0.8 cm thick, brass, plate cast as a duplicate of the “official opening” plaque of the TASCC facility and modified for use at the entrance of the vault housing the superconducting cyclotron. This duplicate of the “master plaque” (artifact 2022-021) was altered by simply removing a 6 cm wide slice referring to the “official opening”. This modified unit was mounted near the cyclotron itself. It also differs in colour from the master as it was painted blue on the unraised sections to match the colour of the cyclotron.
