Blazars are among the largest and most energetic objects in the universe. Jets of matter (“jets”) shoot from the cores of these active galaxies shoot, which are accompanied by huge bursts of gamma rays. An international team led by Lars Fuhrmann from Bonn’s Max Planck Institute for Radio...
Where is gamma rays located on the electromagnetic spectrum? What part of the electromagnetic spectrum is an electromagnetic wave with a wavelength of 0.00015 m? Where do the waves from the electromagnetic spectrum come from? What is the electromagnetic radiation spectrum?
not available for EP0174671of corresponding document: US4682033 A gamma camera (1), has a scintillation block with an entrance window (10) constituted by a mechanically stiff supporting structure which very slightly absorbs X and gamma rays. The entrance window (10) supporting the scintillation ...
Beta-decay is one of the three main types of radioactive decay, the other two being alpha decay, and gamma decay. This type of decay is characterized by the emission of beta rays. Beta rays are nothing but a collection of fast moving beta pa...
One of the more popular candidates for dark matter is Weakly Interacting Massive Particles, otherwise known as WIMPs. Underground detectors are currently hunting for WIMPs and debate has raged over whether gamma rays streaming from the galactic center come from WIMPs annihilating one another...

A source of gamma rays is glued onto a non-magnetic tube (7) located in a ring gap provided by the coils, and tube (7) is fixed to a non-magnetic disk keyed onto the shaft of a small electric motor, so the tube can be rotated in the ring gap. The pref. generator consists of...

The carbon matrix is mounted between two dense materials (3) such as Densimet(RTM: tungsten alloy), so as to stop beta rays, X rays and gamma rays. The materials with good heat conductivity enclose the carbon matrix and the paraffin matrix for stopping the neutron radiation. The dense ...
