Workshops 2019

Each workshop requires an individual registration. Registrations open usually late June, beginning of July, once all summer students have arrived. The exact date and time will be announced by email. To familiarize yourself with the registration visit our Indico: https://indico.cern.ch/category/6274/

Please pay special attention to the workshops requirements, some workshops may require a dosimeter.

How to get a dosimeter

Follow the online training "RP Training for CERN Supervised Radiation Areas" available at https://sir.cern.ch
Go to 55/1-001 (open only from 08:30 - 12:00) and ask for a dosimeter specifying that you're a Summer Student and you need it for a workshop
Last but not least: Please do not forget to bring the dosimeter back after the workshop!

How to attend

Please keep in mind that there is only a limited number of places available. The Summer Student Team will send you all the important information by email.

Characterisation of scintillating fibres

Measure the attenuation length of a scintillating fibre
Measure emission spectrum of a scintillating fibre and the wavelength dependence of the attenuation length
Demonstration of Scintillation Light Yield measurement with a SiPM
Visit of scanner for fibre diameter and cladding quality

Contact: Lukas Gruber
Number of places: 9 students - 3 groups of 3 students
Location: 304-1-004

This laboratory session provides an introduction to the technology of Silicon Photomultipliers (SiPM). We use a measurement setup for the characterization of single SiPM assemblies. Basic properties such as the value of the quenching resistors, the breakdown voltage, the noise rate, the cross talk and the gain are extracted.

Characterization of a simple particle detector using cosmic particles

Hands-on experience with classic photomultipliers, oscilloscopes, scintillators, light guides, wavelength shifters and monochromators.
We start by characterizing the 1 photoelectron signal from the photomultiplier. With that knowledge we then measure the light yield of a plastic scintillator hit by a cosmic particle. We modified the setup to experience the advantages and disadvantages of introducing a wavelength shifter between the scintillator and photomultiplier.
To disentangle the different efficiency involved we measure the quantum efficiency of the photomultiplier as a function of the wavelength.

Data Acquisition / Trigger

The LHCb data acquisition will be explained on a thorough guided tour. Then we will use a test-setup to demonstrate and (compete to) solve some common problems in networked data acquisition systems as they are used by the LHC experiments. We will have fun with switches, network analyzers and data-flow control.

Requirements:

You must wear hard shoes that completely cover your feet: no sandals, no flip-flops, no high-heels.
Bring your CERN badge, ID-card (during the workshop you will go to Point8 in France).

Contact: Niko Neufeld, Tommaso Colombo, Sebastien Valat
Number of places: 16 students - 4 groups of 4 students

MadGraph

Discuss the various aspects of a hard-hadronic collision using a FLASH simulation.
Develop cutting edge Monte Carlo techniques necessary for simulating these collisions.
Use MadEvent’s new web-based capabilities to produce event simulations for processes important to LHC physics.

Requirements: Note that you will need to bring your laptop in order to attend this workshop.

ROOT

ROOT is a tool kit for data analysis, storage and visualization. It is widely used in High Energy Physics and other disciplines.

This three hours tutorial comprises a front lecture and hands on exercises. It will be driven by slides which will present to the students all the basic concepts and tools ROOT provides. They will also guide them through many interactive examples and exercices largely extracted from the "ROOT Primer" handbook.

The attendees will need their laptop to profitably take part in the hands-on sessions during the workshop.

The hands-on sessions will be carried out in two ways: mainly online with the platform offered by the SWAN service (swan.web.cern.ch) and with local ROOT installations on the laptop. Usage of the CERN Lxplus cluster will be also possible. All participants should have a CERNBox before the tutorial: this can be created connecting to https://cernbox.cern.ch (link is external) . The SWAN service can be then reached at the address https://swan.cern.ch (link is external) .
The ROOT version which will be used during the training is ROOT 6.16, available at https://root.cern/content/release-61600). If the student cannot install ROOT on the laptop, they can log in to the lxplus7 cluster, which has a pre-installed ROOT. Please make sure that you can log in to lxplus7.cern.ch using your CERN account and ssh.

This indico page also provides more material which will be used during the exercices. The https://root.cern.ch/drupal (link is external) ROOT web site is a very good source of documentation and help. We will spend some times explaining the various headings one can find there, and will constantly refer to them during all the lesson.

Scintillating Crystals

New Scintillating Crystals are being developed for bio-medical applications, which were first developed for high energy physics or material science. With a new generation of photodetectors being made available for the same applications (HPMTs, APDs, SDCs, etc.), these gamma detectors (crystal + photodetector) represent an important contribution in the evolution of instrumentation for physics and non-physics applications.

CANCELLED FOR THE SUMMER OF 2019

Silicon Sensors

We will investigate how radiation damage is influencing the silicon tracking detector in the LHC experiments. The following properties of irradiated and non-irradiated silicon detectors will be measured: Reverse current, detector capacitance, depletion voltage and charge collection efficiency.
This will give you an impression on how much detectors in the LHC will suffer from radiation damage. In a concluding discussion we will look at some possibilities on how to make detectors radiation harder.

Requirements: a dosimeter is required to attend this workshop.

Web application security penetration testing

In order to protect computers and networks from malicious attacks, we need to find and fix any vulnerabilities before they are identified and exploited by the bad guys (Black Hats). One of the ways to achieve it is to do penetration (security) testing. To do this efficiently, the good guys (White Hats) have to think and act as the bad guys - but with the ultimate goal of securing the target rather than abusing it. In this 4-hour workshop, you will learn the tools, the techniques - and the ethics - of a White Hat penetration tester. We will focus on web applications, as these are the most common targets in any organisation.

The workshop will consist of:

an introduction to web security and penetration testing (1h)
a hands-on part: finding and exploiting vulnerabilities in a simple web application (2h)
a debriefing, discussing the most common types of web application vulnerabilities (1h)

Requirements: The participants will need to bring their laptops to profit from the hands-on part of the workshop.

Working with a Beam Line in the North Area

In this workshop you will, after a short theoretical introduction, work with a test beam in the North Experimental Area at the CERN SPS. You will learn how to steer the beam, study the effect of collimators as a function of their location in the beam optics (momentum slit and acceptance collimators) and measure the beam composition with different methods.

Every participant will be asked to attend a preparatory lecture on Wednesday, 2nd August at 15h00 in 774-R-013 .
