LIS Technologies is on the road to transforming nuclear fuel enrichment through advanced laser techniques, ensuring a sustainable and cost-effective approach to energy production.

For simple low-power applications, beam dumps made of black velvet or flock paper are used, whereas for high power applications gas or water beam dumps are used. Beam dumps are an important part of linear colliders, energy recovery systems. This datasheet will elaborate on the construction, working and applications of beam dumps.

It's a zoom to focus. With the Source Four Fresnel, you get that timeless Fresnel light in a 21st-century fixture. ETC's innovative mechanical design has simplified the focusing for you. Whatever physically awkward spot you're working in, we make it easier for you to adjust the fixture from spot to flood, with a full-sized zoom knob you can get a real grip on. We've also engineered the fixture-housing to eliminate light leaks and minimize spillage.

A beam dump maybe defined as a device used for absorbing the energy from photons or other particles. A beam dump in the context of optics can be described as an optical element that absorbs a beam of light. Selecting a beam dump for the application depends on factors such as power, back-reflection and heat.

With the Source Four Fresnel, you choose the lamp wattage that best suits your particular application and energy requirements - from 375W to 575W to 750W lamps. And when you need to relamp a Source Four Fresnel, ETC's smart new design makes your work easier than ever. Our innovative socket and access door let you change out the lamp from underneath the fixture -- without having to break focus -- saving on work, time and trouble.

We've combined the best of our acclaimed Source Four HPL lamp technology with the unique optics of a traditional Fresnel. (And that means you can further streamline your fixture lamp inventory with a single source - the HPL.) ETC's Fresnel gives you the high-performance light output and energy savings of a Source Four and the lighting characteristics that only a Fresnel optical system can provide. We've combined that classic system with a special ETC dichroic reflector design, enabling the HPL 750W Source Four Fresnel to equal the light output of 1000W Fresnel fixtures.

For efficient energy absorption, a beam dump must be made of material with high conductivity. They must also have high melting temperature and yield stress. Some of the materials used for beam dumps are beryllium, carbon, aluminum and copper. Water and gas dumps are also used for high power applications. Gas dumps are made of noble gases.
