El motor de la Nebulosa del Cangrejo

El púlsar en el corazón de la Nebulosa del Cangrejo bulle de energía. Los telescopios MAGIC en la isla canaria de La Palma lo han confirmado tras detectarlo en rayos gamma de 25 a 400 gigaelectronvoltios (GeV), una banda de energías que estaba prácticamente inexplorada hasta la fecha. Ahora MAGIC se ha encontrado con que las señales que emite esta estrella llegan hasta energías tan altas como 400 GeV, entre 50 y 100 veces más de lo que predice la teoría. Esto ha dejado perplejos a los científicos, porque podría apuntar a un proceso astrofísico aún desconocido.

La estrella de neutrones que alberga la Nebulosa del Cangrejo es uno de los púlsares más famosos. Rota alrededor de su eje 30 veces por segundo y tiene un campo magnético de 100 millones de teslas. Este campo magnético es un billón de veces más intenso que el de nuestro planeta. El púlsar, que está a 6.000 años-luz de la Tierra, en la constelación de Tauro, es el motor de la Nebulosa del Cangrejo que le rodea. Tanto el púlsar como la nebulosa son los restos de una explosión de supernova que tuvo lugar el año 1054, y que llegó a ser tan brillante que se veía durante el día.

New refresher training in the use of self-rescue masks

Photos of the training session for self-rescue mask instructors held on 21 March 2012 – 10 new instructors followed the coursePhotos of the training session for self-rescue mask instructors held on 21 March 2012 – 10 new instructors followed the course

 

A refresher course in the use of self-rescue masks has been added to the CERN training catalogue.

Sign up!

More than 3500 people have followed the course since it was introduced in 2009.

Taking account of the forthcoming long shutdown, requests for follow-up training from course participants and recent changes in the course content, the HSE Unit has decided to place a three-year limit on the validity of the initial training and to introduce a refresher course.


The new refresher course is open to all personnel having completed the initial course at least 2 years ago.

The course, "Recyclage Formation masque auto-sauveteur » / "Refresher course Self-Rescue Mask Training", (code No. 077Y00R) is already available from CERN's training catalogue.
The first sessions are scheduled for April 2012.
The course will be offered in French and English and, like the initial course, will comprise both theory and practical sessions, including simulations under real conditions.

The Safety Training team anticipates a significant increase in requests for training before and during the first long shutdown known as LS1. You are therefore recommended to sign up for a course well in advance of the start of the shutdown if the validity of your training expires within the next year.

Please note that the Safety Training Service will send a reminder to all those whose initial training is due to expire during LS1.

If you are unsure when you followed the initial course, you can find the date in the HRT application (https://hrt.cern.ch/hrt/Training).

Academic Training Lecture: Statistical Methods for Particle Physics

2, 3, 4 and 5 April 2012
Academic Training Lecture 
Regular Programme

from 11:00 to 12:00 -  Bldg. 222-R-001 - Filtration Plant

Statistical Methods for Particle Physics
by Glen Cowan (Royal Holloway)


The series of four lectures will introduce some of the important statistical methods used in Particle Physics, and should be particularly relevant to those involved in the analysis of LHC data. The lectures will include an introduction to statistical tests, parameter estimation, and the application of these tools to searches for new phenomena.  Both frequentist and Bayesian methods will be described, with particular emphasis on treatment of systematic uncertainties.  The lectures will also cover unfolding, that is, estimation of a distribution in binned form where the variable in question is subject to measurement errors.
