A 50 cm wide by 47 cm tall, 0.8 cm thick, brass plate cast to commemorate the official opening of the Tandem Accelerator SuperConducting Cyclotron (TASCC) facility on 1986 October 03 by Robert Despres, Chairman of the Board of AECL. The plate features the stylized depiction of the cyclotron and the “tascc” logo on a background of a stylized periodic table. The plaque stood on the outside of the facility. On the back it featured four bosses with setscrews that allowed it to be held to 1 cm posts imbedded on the wall. The facility featured a High Voltage Engineering MP model tandem accelerator and a superconducting cyclotron built at Chalk River by the Accelerator Physics Branch. The facility was decommissioned in 1997 due to financial constraints and largely dismantled for recycling.
