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.

The ICTR-PHE 2012 conference : alliance between the physics and medical communities

The ICTR-PHE 2012 conference, which closed its doors on March 2 after five busy days, sealed the alliance between the physics and medical communities. Some of the most futuristic research in medical physics was presented at the conference. Special emphasis was placed on medical imaging devices, currently used for diagnosis but with the potential to provide crucial real-time monitoring of treatment in the future. Radio-oncologists and radiotherapists represented a large proportion of the doctors and clinicians who attended the conference. With them were also biologists and doctors of nuclear medicine. They presented the state of the art of their research that touches on the genetics and biology of tumours as well as on futuristic drugs that selectively target malignant cells. The future of cancer treatment seems to lie in the personalised approach.

Las Estrellas Enanas Rojas de la Vía Láctea tienen Miles de Millones de Planetas Rocosos en sus Zonas de Habitabilidad

Nuevos resultados del cazador de planetas HARPS, de ESO, muestran que los planetas rocosos no mucho mayores que la Tierra son muy comunes en las zonas habitables en torno a estrellas rojas débiles. El equipo internacional estima que debe haber decenas de miles de millones de planetas de este tipo sólo en nuestra galaxia, la Vía Láctea, y probablemente haya cerca de una centena en las vecindades del Sistema Solar. Esta es la primera vez que se mide de forma directa la frecuencia de súper-Tierras en torno a enanas rojas, las cuales suponen el 80% de las estrellas de la Vía Láctea.

En el CERN ya se trabaja en sucesores del LHC

Si el LHC no revela signos de una nueva física de este año, su posible descubrimiento deberá esperar por lo menos hasta 2015, cuando las colisiones se produzcan allí de nuevo a más altas energías. En cualquier caso, los sucesores del LHC tienen como horizonte 2040, incluyendo un gran colisionador de protones y electrones, que ya está bajo consideración.

http://teknociencia.es/videos/experimento-seis-mil-millones-por.flv

Durante el año 2012, se producirán colisiones a 8 TeV en los detectores ATLAS y CMS en el LHC. Esperábamos la revelación de la existencia del bosón de Higgs, y más signos de la nueva física (especialmente en forma de partículas de materia oscura), ya sea a través de las características del bosón de Higgs. De lo contrario, es probable que tengamos que armarnos de paciencia, porque al final de 2012, las colisiones se pararán durante dos años.

Data Protection for All

What a stir… was caused by two articles in the last issue of the Bulletin, on “New Snail Mail Scanning Service” and “CERN meets Facebook”!

 

Indeed, respondents were completely correct that opening letters addressed to others and scanning such letters violates basic privacy rules. Also, giving your photo, address, computing accounts, personal files and documents to a third party - especially an external party - is a NO-NO, as CERN considers some of this data to be personal. For example, your CERN mailbox and your “private” folders on AFS and DFS are 100% yours. Neither your supervisor, the AFS/DFS/mail service administrators nor the Computer Security Team have any right to access this data. Strict procedures have been established for the rare cases where such access is necessary, and these require the approval of the CERN Chief Information Officer (CIO), the Legal Service and the DG.

But did you know that CERN is currently developing a data protection policy and the role of an appointed CIO (currently assumed by a combination of the head of the IT department and the Computer Security Officer)? Apart from Administrative Circular No. 10, data protection currently relies on the awareness and care of the individual. Not one of your problems? Indeed, CERN thrives on an open culture, so it is tempting to assume “we have nothing to hide”. Losing physics data might be a nuisance, but isn't that all? Still, there are your personal files, mailbox, financial and contractual data, confidential notes and minutes, passwords and credentials, and your medical records. These have to be protected in a consistent and clear way!
 
So we are set for change. In collaboration with the Legal Service and the GS, HR and IT departments, the computer security team is drafting a comprehensive data protection policy for storing, accessing and transferring data. Currently, the focus is on the proper definition of classification levels, i.e. “public”, “internal”, “restricted” and “sensitive”, and an exhaustive list of examples for each level (see here). This policy will be supplemented by policies on data storage, transfer and access. The list of examples will help to clarify classification and avoid incorrect classification within a data store. Finally, the data protection policy includes a policy on data destruction that has already been deployed (see here; see also our article in the Bulletin 10-11/2012).

However, the best way to protect data is still by being conscious and cautious! If you think some documents, files or data should be protected, make sure that they are. We are ready to help you with that.
