Lecture in High Energy Physics II (Astroparticles Detection)


Speaker:Dr. Eduardo de la Fuente Acosta
Affiliation:Instituto de Astronomia y Meteorologia, Universidad de Guadalajara
Date:September 13, 2017 (Wednesday)
Time:3:00 p.m.
Venue:Room 522, 5/F, Chong Yuet Ming Physics Building, HKU

Abstract
 

In this second lecture, tying into the topics presented in my previous lecture, I will give an overview of Astroparticles, including how they are detected and how the physical studies are performed after their detection (e.g. sky maps). In fact, thanks to current technology, it is possible to produce unprecedented maps and obtain results that were previously unattainable. The detection of Astroparticles is complicated and it is very different to Optical and Radio astronomy techniques. I will present a short summary of the different techniques used by existing instruments but will focus on the Cherenkov Radiation Effect. In this technique, unlike other areas of Astronomy, we do not use "secondary mirrors" or similar devices, therefore it is very important to use simulations (e.g. Monte Carlo) and link them with the instrument. Finally, it is not possible understand how the Astroparticles are detected without knowledge of what an Extensive Air Shower (EAS) is, and how it is produced in the Earth's Atmosphere. In this lecture I will give a short summary of EAS and will end with a summary of the current status of the field and what is in store for the future.  

Coffee and tea will be served 20 minutes prior to the lecture.
Anyone interested is welcome to attend.
