McMaster University Tandem Accelerator Lab

Back to case studies

The Centre for Electrophotonic Materials and Devices at McMaster University does research in nearinfrared and mid-infrared optical materials and devices, and contains apparatus such as Gas Source Molecular Beam Epitaxy for the growth of compound semiconductor crystals, and Plasma Enhanced Chemical Vapour Deposition for the deposition of dielectric films. 

The new addition consists of two storeys and a partial basement. The structure uses precast concrete slabs to provide unobstructed lab and mechanical room spaces and to expedite the floor construction. Adjacent building floor slab on grade required soldier pile shoring to permit column foundation installation. 

The mechanical system consists of central air handling units designed to provide ventilation, steam heating and chilled water air conditioning. 

Dedicated exhaust systems were designed for the toxic machinery, general lab ventilation and general lab exhaust. Nitrogen, compressed air and chilled water piping circuits were also designed to service custom made equipment and machines in the Laboratory. Energy Management System was also designed and implemented to control and monitor all the mechanical equipment and systems. 

New addressable fire alarm system was designed to provide adequate fire protection in the new addition as well as to replace antiquated fire alarm panel in the existing building. Energy efficient fluorescent “T8” lighting with instant start electronic ballasts provides level of illumination required for conducting experiments in the new laboratory.
