New Isolde Synoptic project


The On
-
Line Isotope Mass Separator ISOLDE is a
facility

dedicated to the production of a large variety
of radioactive ion beams for a great number of
differe
nt experiments, e.g. in the field of nuclear and
atomic physics, solid
-
state physics, life sciences and
material science. At ISOLDE, radioactive nuclides
are produced in thick high
-
temperature targets via
spallation, fission or fragmentation reactions. The

targets are placed in the external proton beam of the
PS Booster, which has an energy of 1.4 GeV and an
intensity of about 2µA.


The aim of the New Isolde Synoptic project is to
develop a synoptic
-
like graphical user interface
(GUI) application for the mo
nitoring of the Isolde
accelerator complex. The main idea is to have it
completely configurable by the Isolde machine
supervisors.


The project is structured in three main parts: the
editor, the server and the client applications, as
shown in figure 1.





Fig. 1 Software project scheme


The editor application, also called “Synoptic
Builder”, is used to create, edit and modify a
synoptic. Figure 2 shows the user
-
friendly GUI,
which allows any users to drag and drop new
devices and define custom threshold s
ettings for the
visualization (Fig. 3). All elements can be grouped,
resized and rotated.

Fig. 3 Configuration of a device


Once the synoptic interface has been finished, it is
saved in form of a XML
file. This File is then
automatically loaded onto the server.

The server
software is the core process of the project. It is
written in Java and running on a BE
-
CO server rack.
The server process monitors every device specified
by the synoptic files. The se
rver uses JAPC
-
Monitoring in order to manage the data acquisitions
efficiently via subscriptions for all the numerous
devices.


Every 1.2 seconds the server retrieves the settings
and acquisitions of all the devices specified in the
synoptic files. The dat
a is then distributed to all
connected clients either via a TCP/IP socket or via
xml files (web
-
clients).


The status of each device is computed in different
ways depending on their type. For instance, all the
vacuum valves and the Isolde beam diagnostic
d
evices return their state (CLOSED/OPEN &
IN/OUT). The status of all the other devices, e.g.
quadrupoles, kickers and dipoles, are calculated
according to the comparison of the acquisitions
(AQN) vs. the settings (CCV) and their tolerance
(relative: TOLR &
absolute: TOLA). For those

devices the status is considered to be good, if |AQN
-
CCV|<TOLA or ||AQN
-
CCV|/AQN|<TOLR.


There are two client java applications. The “viewer
application” runs only on the technical network and
can access directly to the server, s
ee figure 4. It
refreshes all the data every 1.2 seconds and can be
started from the Isolde console manager.

The second one is a web
-
client application, which
shows the synoptic on a web page, see fig
ure 5.It
combines HTML5 with JavaScript code. The web
-
client has a refresh period of 10 seconds and offers a
history graph for each monitored device.




Fig. 5 Web
-
client application


The client applications display the status
informations and the current

values of each
monitored device. Whereas the status of each device
respects the following colour scheme:

GREEN:

device tolerance respected as previously
described or beam diagnostic OUT or Vacuum valve
OPEN.

RED:

device tolerance not respected or beam
diagnostic IN or Vacuum valve CLOSED.

GRAY:

device OFF.


For the moment this project has been developed for
Isolde, but in the future we would like to merge it
with the “Inspector” software written by Bertrand
Lefort (BE
-
OP
-
AD). This will be done in order to
give the operators more powerful tools like
customized

graphics, images and other widgets, as
well as offering an easier way to make new schemes.

Nivellement rapide dans le LHC


Dès le début du LS1, la section Survey (SU) a
entamé une campagne

de «

nivellement rapide

» sur
les 27 km du LHC. L’objectif de cette opération est
double

:




déterminer la hauteur des aimants avant
l’ouverture des interconnections, pour pouvoir
comparer avec la position précédente mesurée
pendant l’arrêt machine 2008
-
20
09 et avoir des
statistiques sur les mouvements des aimants à
cause de l’instabilité des ouvrages
.



Avoir une nouvelle position absolue des
références installées profondément dans la
molasse 25 m plus bas que le niveau du tunnel
LHC, la mesure initiale fai
te en 2004 ayant été
perturbée par des conditions environnementales
mal maitrisées
.


Le nivellement est l’opération qui permet de mesurer
des dénivelées entre des points puis d’en déduire
leur altitude. Elle s’effectue à l’aide d’instruments
appelés nivea
ux, qui matérialisent très précisément
un plan horizontal. Ils peuvent être optiques, la
lecture sur la mire graduée étant faite par
l’opérateur, ou digitaux, dans ce cas la lecture est
faite par une caméra CCD incorporée dans
l’instrument.

Colonne Sécurité

Faites
-
vous remarquer en tout temps avec votre vélo


Pour être en sécurité de jour comme de nuit, il faut
deux choses :

1.

Voir correctement

2.

Etre vu correctement


Pour
voir correctement
, nous vous conseillons
d’utiliser une lampe frontale fixée sur le casque avec
un faisceau bien concentré sur la route.
L'avantage
principal de la lampe frontale est de suivre les
mouvements de votre tête.

Pour
être vu correctement
, n'hésitez pas à porter des
vêtements clairs pourvus de bandes réfléchissantes.

Quel est le minimum requis par la loi ?

Un feu blanc à l’avant
et un feu rouge à l’arrière non
clignotant.

Au minimum, deux catadioptres (c’est
-
à
-
dire un
dispositif qui permet de réfléchir les rayons lumineux)
-

dirigés l’un vers l’avant, l’autre vers l’arrière.

Catadioptres sur les pédales, à l’avant et à l’arrièr
e.

Et bien sûr toujours le casque et le gilet jaune avec
des bandes réfléchissantes pour une sécurité
optimale ! Ceux
-
ci peuvent être commandés via votre
superviseur.

Be seen any time when biking


To bike safely day or night, you need 2 things:

1.

See properly

2.

Be seen properly


In order to

see properly
, you are invited to use a
head lamp attached on your helmet and directed to
the road. The main asset of head lamps is that they
follow every move of your head.

In order
to be seen properly
, do not hesitate to
wear light
-
colored clothes with reflective st
rips.

What does the law require?

You must have a white front lamp and a red non
-
flashing back lamp.

You must have a minimum of 1 front and 1 rear
retro reflectors.

You must also have retro reflectors set on the front
and the back of your pedals.


And
of course, you must always wear your helmet
and the yellow vest with reflective strips which
will ensure your total protection! You can order
these items via your CERN supervisor.

Pedestrian and
cycle entrance

A second entrance for pedestrians and cyclists on
Route du Maroc will be opened and the existing
entrance on Chemin du Moulin
des Ponts will be
re
-
opened:



for the period 2 April to 31 October 2013,




from 7.00 a.m. to 9.00 a.m. and from 5.00 p.m.
to 7.00 p.m. on working days
.



IMPORTANT
: all users
must

show their access
cards to the security guard as a matter of course
when passing through the gates, both on entering
and leaving the site.





Human Resources Advisors

provide advice to
the departments, individual supervisors and
members of the personnel, whilst ensuring the
implementation and coherent application of
policies and procedures. At the same time, they
contribute to the policy
-
making process.
