National laboratories throughout the world rely on our interconnect systems for trouble-free operation under frequently harsh conditions and in radiation environments. We are knowledgeable with regard to these systems and we can intelligently communicate with physicists and engineers in the various disciplines.

Resulting from our close association with the high energy physics industry, we are often called upon to provide unique solutions to a variety of problems.

One significant and continuing line of products that have evolved from these efforts is useful to those experimenters in the neutron scattering community.

Neutron Detectors

The Brookvine division of Essex X-Ray, a sister company of DSI and a member of the HVT Group, designs and manufactures fiber optically coupled scintillating neutron detectors. These units are currently installed at the Rutherford Appleton Reasearch Laboratory on both ISIS and NIMROD.


DSI is the developer and manufacturer of ZHIP (Zero Hydrogen In Product) Mix, a composite material of boron carbide (B4C) and a non-hydrogenous binder used for shielding the interior of neutron scattering equipment such as neutron sources and detectors. ZHIP Mix has superior characteristics to “crispy mix”; the open matrix structure results in lower outgassing and pumpdown time and the absence of hydrogen yields a lower albedo. ZHIP Mix is provided in premolded shapes, typically panels, which are either self- supporting or backed by a supporting aluminum sheet. Tubular forms for pipe lining and a variety of custom shapes are also available.
