Course Description:

At first glance, building an electromagnetically shielded room seems to be just another construction project. It is far from that. Shielded rooms involve a unique combination of construction and electronic assembly skills that only a few firms possess. Without some background in this unique technology, purchasers can find themselves with shielded rooms which, while they may have a good appearance, also have many electromagnetic leaks. Finding and fixing those leaks can be a slow and expensive proposition.

The objective of this course is to help participants avoid the most common technical and contractual pitfalls that are involved in the acquisition, use, maintenance, and life-cycle management of electromagnetically shielded rooms. This course will help buyers obtain well designed, long lasting shielded rooms quickly and economically. All participants will gain the knowledge necessary to make rational and intelligent management decisions regarding the design, contracting, construction, testing and maintenance of these unique structures.

This course is technical in nature, but no extensive engineering education or experience is required. Those in government or industry whose responsibilities involve the acquisition, installation or management of shielded rooms will find that this course will save them many times its modest cost.
