Abstract:
A method of making a radiation sensing system for detecting electromagnetic radiation and transmitting a sensory signal therefrom, comprising the steps of:forming a body from an inexpensive material, the body including an outlet portion and an inlet portion;forming a radiation sensor;inserting the radiation sensor substantially into the outlet portion of the body;forming a plug from material resistant to radiation damage, the plug including an inlet, an outlet, and a bore therethrough, whereby electromagnetic radiation travels through the plug via the bore;inserting the plug substantially into the inlet portion of the body;placing a lens over the inlet of the plug;forming a cap including a top plate and a side wall extending outwardly from the top plate; andsecuring the cap over the inlet portion of the body, comprising the steps of:forming a scraping notch in the side wall, the scraping notch engaged with the body;forming an annular cavity defined by the sidewall of the cap and the body as the sidewall is placed over the body;positioning the scraping notch against an aggregation of sealing material in a substantially solid phase to define a first position;deforming the aggregation of sealing material;inserting the cap further along the body from the first position to a second position;directing the deformed aggregation of sealing material with the scraping notch from the first position across a ridge from the body to a second position, whereby the aggregation of sealing material collects in the annular cavity; andresolidifying the aggregation of sealing material within the annular cavity thereby wedging the cap to the body.
