All charged up!

Beams of energetic charged particles are vital for scientific research. In this "Up close with Science" session we'll be live at the TIFR-BARC Pelletron LINAC facility - the particle accelerator systems at TIFR. These machines accelerate ions to very high energies, and beams of such ions are then directed to towards “targets”, where they interact with atomic nuclei, allowing scientists to probe the nature of nuclear matter. The LINAC is a superconducting linear accelerator that boosts the energy of heavy ion beams delivered by the Pelletron accelerator to even higher energies. The radiations emitted in these high-energy interactions are sensed by arrays of detectors. We’ll see INGA - the Indian National Gamma Array - a powerful state-of-the-art detector setup to study structure of atomic nuclei at high spins. Join us for an amazing online tour of this mega experimental facility!

Thank you

Difficult to understand.

Here's a summary for you. He is giving tour of Pelletron, a particle accelerator in TIFR, Mumbai. Here ions (charged nuclei) are accelerated to a few MeV energy and the beam of ions fall into different target material (with target nuclei). The accelerator itself is made in a tower that is n meters (think 7 floor tall)... At the ground floor in the tower there are experiment halls where different experiments are done. In the experiment hall you can see the beam pipe through which accelerated ions travel. Whenever there is a bend in the path of the beam line, to bend the ions there are bending magnets. To focus the ions focusing magnets are used. (This field is called beam optics btw). In one of the experiments that he is working on, the accelerated ions will be bombard on fixed target. This will form "compound nucleus" which will decay into "excited states" which will decay into gamma rays (photon). Around the target gamma ray detectors are kept.
